Fiber Optic Connector Manufacturer

Connector Families: Specs, MOQ and Lead Time

Every connector family this fiber optic connector manufacturer builds is listed below with the two numbers buyers ask first - MOQ and lead time. Lead time runs from deposit and includes polishing, 100% optical testing and packing.

Family	Options	MOQ	Lead time
SC connectors	UPC / APC, SM or MM, 0.9 / 2.0 / 3.0 mm boots, simplex or duplex clip	500 pcs	5-8 days
LC connectors	UPC / APC, SM or MM, 0.9 / 2.0 mm boots, simplex or duplex clip	500 pcs	5-8 days
ST / FC connectors	Metal body, UPC, SM, 0.9 / 2.0 / 3.0 mm	500 pcs	6-9 days
Connector kits	Zirconia ferrule + full part set, color-matched	200 sets	6-10 days
MPO / MTP kits	Push-pull boot, 2.0 / 3.0 mm, male or female	200 pcs	8-12 days
Hybrid conversions	LC-SC female-to-male and mixed heads	500 pcs	6-9 days
Pigtail-type 0.9 mm	For splicing into closures and ODFs	1,000 pcs	5-8 days

MOQ and lead-time figures are standard production windows; Chinese New Year peaks can add 5-7 days. Fixed dates are confirmed in writing on the proforma invoice.

What buyers order most from this shelf

• SC/UPC 2.0 mm single-mode: the FTTH workhorse - closure splices and ONT pigtails both draw from this line.
• SC/APC 2.0 mm single-mode: green boots for RF-over-glass and CATV networks.
• LC/UPC 0.9 mm multimode: OM3 and OM4 patch cord lines buying ferrules and kits by the thousand.
• Connector kits: field crews and cord workshops order parts sets to stop juggling seven vendors.
• MPO push-pull kits: data center trunk builders fitting 2.0 mm and 3.0 mm boots.

These five SKUs cover most purchase orders. The full shelf sits in the product grid above - every build runs to your boot color, cable size and polish spec.

Anatomy of Our Connector: Parts That Decide Performance

A connector is seven parts doing one job. Buyers who know the parts also know why prices differ between suppliers:

• Ferrule: zirconia ceramic, 2.5 mm (SC/FC/ST) or 1.25 mm (LC) - the part that holds the 125 µm fiber to sub-micron alignment. We use ceramic only; plastic ferrules never enter the line.
• Body: brass or zinc alloy housing that clamps the ferrule without stress.
• Spring: stainless, rated to keep constant end-face contact pressure across 500 mating cycles.
• Crimp tube and stop: kevlar-grip crimping and strain-limit stop for the cable size you run.
• Boot: 0.9 / 2.0 / 3.0 mm, color-coded by fiber and polish type - blue UPC, green APC, aqua OM3/OM4, rose OM4, orange OM1/OM2.

Order the full set as a kit and every part arrives matched - ferrule, body, spring, stop, crimp tube and boot in one bag, ready for the line. Kits exist because mismatched parts are the top cause of failed terminations at buyer workshops.

SC, LC, FC, ST: Choosing the Interface

Four interfaces cover 95% of orders. Pick by the equipment port and the panel density - not by habit:

Interface	Ferrule	Mechanism	Home ground
SC	2.5 mm	Push-pull latch	FTTH, ONTs, CATV - fast to handle with gloves
LC	1.25 mm	Small latch	Data centers and SFP ports - half the panel space of SC
FC	2.5 mm	Screw-on thread	Test instruments and legacy telecom - vibration-proof
ST	2.5 mm	Bayonet twist	Campus backbones and industrial cabinets
MPO/MTP	Multi-fiber	Push-pull, 8-72 fibers	40/100G trunk links and cassettes

Mixed networks are normal: SC at the ONT, LC at the switch. That is why our MOQ works per type - you order 500 of each instead of 5,000 of one.

How a Connector Is Made: Seven Steps in Our Cell

Buyers who see the process understand both the price and the yield of a working fiber optic connector manufacturer. One connector passes seven steps before it reaches the bag:

1. Fiber prep: the 125 µm glass fiber is stripped, cleaned and cut to length for the ferrule bore.
2. Epoxy fill: adhesive injects into the ferrule bore so the fiber bonds with no air gap - voids kill return loss later.
3. Cure: the loaded ferrule cures in a precision oven at set temperature and time.
4. Coarse polish: the cured fiber tip grinds down on lapping film - 9 µm, then 3 µm, then 1 µm grits.
5. Fine polish: the final pass sets the geometry - radius, apex offset and fiber height, UPC or the 8-degree APC angle.
6. Inspection: a 400× scope checks the end face against IEC 61300-3-35, and interferometer sampling reads the geometry.
7. Assembly and test: body, spring, stop and boot go on, then 100% IL and RL on the bench before packing.

Each step has a reject gate. Lots that miss the geometry window never reach assembly - the scrap stays in our bin, not in your patch panel.

Factory Polish vs Field Termination

Connectors reach the field two ways, and the right one depends on the job:

• Factory-polished connectors (this page): cured, polished and tested under controlled optics. Best for patch cord lines, closure work with splicing, and any build that wants measured return loss on paper.
• Field-installable connectors: pre-polished stubs crimped on site in about a minute, no oven or polish table. Best for last-mile drops where a splicer cannot reach.

Many crews run both: factory connectors on the frame side, field-installable units at the drop. Our fast connector - the patented design from our own R&D - covers the field side, so one factory serves the whole termination plan.

Six Termination Failures and the Part That Stops Each

Field failures trace back to parts more often than to skill. Match the failure to the part:

• High return loss after install - epoxy voids behind the ferrule. Our bore-fill step and cure spec remove the void.
• Chipped fiber tip - over-polish on cheap film. Grit sequence and film change intervals are fixed in our cell.
• Loss that drifts with temperature - plastic ferrules. Zirconia ceramic holds geometry from -40°C to +70°C.
• Cable pull-out - weak crimp tube grip. Our crimp tubes bite kevlar and jacket, rated for 50 N pulls (draft spec).
• Dusty end faces - storage without caps. Kits ship with dust caps seated at assembly.
• Wrong boot on site - color confusion. Boots arrive color-coded to fiber and polish on every order.

Six failures, six parts - and each part in our kits carries the spec that closes it. That is the quiet argument for buying kits from the factory instead of parts from a shelf.

Ferrule Geometry, Decoded

Three numbers on an interferometer sheet decide how two ferrules mate. Read them like this:

• Radius of curvature (ROC): how round the polished tip is. Too sharp and the fiber crushes under contact force; too flat and the pair loses contact. UPC typically sits in a 10-25 mm window (draft).
• Apex offset: how far the polish peak misses the true center. Offset pushes contact to one edge - the cause of "loss that changes when you re-seat the plug."
• Fiber height: how proud or sunken the glass sits versus the ceramic. Proud scratches the mating face; sunken creates an air gap and a return-loss spike.

Our interferometer sampling reads all three per shift, per lot. Buyers building cords on their own lines receive the geometry data with ferrule and kit orders - it feeds straight into their polish recipes.

Polish Quality: The Numbers on Our Test Sheets

Polish decides the return loss at every port a fiber optic connector manufacturer serves, and return loss decides signal quality. Our bench numbers, tested on every batch:

• Insertion loss: ≤0.3 dB typical, ≤0.5 dB maximum.
• Return loss: ≥50 dB UPC, ≥60 dB APC (single-mode); ≥20 dB multimode.
• Ferrule geometry: radius of curvature, apex offset and fiber height verified by 3D interferometer sampling within IEC windows (draft tolerances - confirm per drawing).
• Durability: ≤0.2 dB change across 500 mating cycles in design testing.

Finished connectors never skip the bench: 100% of each batch reads IL and RL before packing, and the readings ship with the goods. A connector without test data is just a plastic part - with data, it is a measured component.

OEM, ODM and Private-Label Capability

As an OEM fiber optic connector manufacturer, we build to your boot color, marking and packaging spec. Three service levels:

• OEM: laser marking on housings, private-label polybags and kit boxes, free artwork proofing above 2,000 pieces.
• ODM: custom boot molds, duplex clip designs and kit configurations - samples in 10-15 days after drawing approval (draft).
• OBM / JDM: exclusive part numbers and stocking terms for distributors, under NDA with locked seasonal pricing.

OEM projects we shipped (draft references - replace with your approved cases)

• European patch cord producer, 2024: 200,000+ LC/UPC 1.25 mm ferrule kits per year under a frame agreement, laser-marked with the buyer's part code.
• South Asian ISP program, 2023: 150,000 SC/APC 2.0 mm connectors for FTTH closure splicing, green boots, four shipments across the build season.
• US MPO trunk builder, 2025: push-pull MPO kits in 2.0 mm and 3.0 mm with private-labeled kit boxes, quarterly call-offs.

Connectors from this fiber optic connector manufacturer pair naturally with the rest of the line: finished patch cords and pigtails assembled in our own workshop, adapters to mate them, and the field-installable fast connector - the patented design our R&D lead developed - for crews who terminate without a splicer.

Certifications and Compliance

The factory runs under ISO 9001:2015, with CE reports covering connector families sold into the EU. Connector interfaces follow IEC 61754 footprint standards, so they mate with standard adapters and tooling worldwide. Documents are public on the certificate page and copies join every quote.

Certificate	Relevance to your connectors
ISO 9001:2015	Quality management for assembly, test and shipment
OHSAS 18001:2007	Occupational health and safety management
CE reports	Connector families shipped into the EU (UDEM issued)
Utility model patent	Fiber optic quick connector - the factory's own R&D, by Zhou Liubo

Materials: RoHS-compliant plastics and ceramics on request, with material certificates available per batch.

Custom Boots, Colors and Kit Specs: How an OEM Order Runs

Custom work follows a fixed path. Send the boot drawing or a sample connector; engineering returns a drawing for approval in 3-5 working days. First articles run in 10-15 days after approval (draft), and volume follows the standard lead-time table. The MOQ for custom boot colors starts at 2,000 pieces per color, and laser-marked housings start at 2,000 pieces. Everything stays on file - a repeat order twelve months later reproduces the same color code, ferrule spec and packaging without a new discussion.

Working with an established fiber optic connector manufacturer on custom parts also protects your line: our R&D cell holds the tooling drawings, the interferometer baselines and the boot material specs, so your replacement order in year two matches the first batch piece for piece.

Wholesale Program for Connector Buyers

Connector volumes run high and margins run thin, so the wholesale program at this fiber optic connector manufacturer is built for arithmetic:

• Tier pricing: steps at 5,000, 20,000 and 50,000 pieces per order cycle; kits count piece-for-piece.
• Mixed SKUs: SC, LC, kits and MPO parts share the container and the price tier.
• Stock call-offs: frame agreements reserve monthly production slots at fixed prices.
• Private label: bags, boxes and laser marks under your brand.
• Documentation pack: certificates, test sheets and photos for your tender file, refreshed each cycle.

Distributors typically start at the 5,000-piece tier, prove the return rate, then move to call-off terms inside two cycles.

Factory Strength: The Line Behind the Ferrule

Connector assembly shares the Yiwu compound with our cable extrusion and patch cord benches - 25 years under founder LING LI, since December 2000:

• Assembly: dedicated polishing cells for UPC and APC, with interferometer sampling at the polish stage - problems stop at the machine, not at your panel.
• Test benches: every batch reads IL and RL on calibrated equipment; interferometer geometry checks guard the ferrule lot.
• Quality: Grace Xu, Quality Director, releases every batch against the test sheet.
• R&D: Zhou Liubo, Director of R&D and quick-connector patent holder, owns new-mold development.
• Export: Peter Lin, Head of Export Sales - one contact for quote, production photos and documents. Video audits run any business day - see the factory gallery.

Why Buyers Pick HENGXANG Over Other Suppliers

Connector price differences look small per piece and huge per project. Here is where this fiber optic connector manufacturer differs:

Factor	HENGXANG	Typical trading company
Test data	100% batch IL/RL, readings in the box	Sampling at best, no data
Ferrule	Zirconia ceramic only, interferometer-checked lots	Mixed sources, plastic ferrule options
MOQ	200-1,000 pcs by family	5,000 pcs minimums
Quote speed	Within 24 hours on business days	Days
Range	Connectors + cords + cable + adapters, one container	Single category
Engineering	Patent-holding R&D for custom boots and kits	None in-house

One habit worth naming: we reject ferrule lots at incoming inspection - and we tell the buyer when we do it, because a failed lot never becomes their failure in the field.

After-sales follows the same discipline. A claim needs the batch label and the field reading; our bench re-tests retained samples from the same lot and answers with numbers. Confirmed factory faults replace in the next run - most within 10 days (draft). It is the working style of a fiber optic connector manufacturer that plans to ship to you for the next decade, not the next quarter.

Storage and Shelf Life: Keep Lots Test-Ready

Connectors age in storage more than in service. Three habits keep a lot test-ready until the day your line calls for it:

• Keep the caps on: dust caps stay seated from our bench to your polish bench - one open shelf week can cost a re-wash cycle.
• Mind the ferrule date: ferrule lots hold geometry indefinitely, but epoxy-loaded tips age; rotate stock so loaded connectors assemble within 6 months (draft guidance - confirm per your process).
• Store dry and boxed: original cartons with desiccant, off concrete floors. Jacket colors fade and housings scratch on open racking.

Warehouses that follow those three rules open a year-old carton and run it straight through the tester - which is the whole point of buying tested parts from a fiber optic connector manufacturer in the first place.

• Step 6 - Shipment: EXW, FOB Ningbo/Shanghai or CIF; documents within 3 working days of sailing.

Worked Example: A 20,000-Piece SC/UPC Program

Illustrative figures - your quote states yours. A patch cord workshop orders 20,000 SC/UPC 2.0 mm single-mode connectors for its production line:

Step	Detail
Day 0	Inquiry received; quote issued next business morning at the 20k tier price
Day 1-2	Samples airfreighted from stock for line trials
Day 3-8	Production: polish cells run the ferrule lot, interferometer sampling each shift
Day 8-9	100% IL/RL bench on all 20,000 pieces; batch file exported to the buyer's template
Day 10	Carton pack with private-label polybags; ~9 cbm, one pallet set
Day 11	Trucked to Ningbo, FOB; documents issued 2 days after sailing

Eleven days, one accountable contact, and a batch file that plugs into the buyer's QA system. That is what ordering direct from a fiber optic connector manufacturer looks like on a schedule.

One Supplier for the Whole Termination Chain

Connectors are one link in the chain your project pulls through the field. The same plant ships the cable, the cords and pigtails, the adapters, the field-installable fast connectors, the termination boxes and the ODFs that hold it all. Planning the split points? Start with PLC splitters, and read our ODF planning guide before the rack layout locks. One purchase order, one freight plan, one warranty conversation.
