Product Overview

FC Connector SM is part of the fiber optic connector range built by Ever Expresslink Limited in Ningbo, China. It is built on the FC (Ferrule Connector) interface.

FC fiber products and FC fiber optic connectors are widely used on the equipment and cable assemblies, especially on the test equipment interface. FC is designed with cylindrical metal coupling nut with keyed sleeves, it is used in long haul and local network connections. FC fiber optic connector use 2.5mm ceramic ferrule and the FC ferrule are with pull-proof mechanism for durability.

Generally we use FC fiber optic connector the housing made by metal. Totally there are three types FC fiber connectors: single mode FC UPC FC fiber connector, single mode FC APC fiber connector and multimode FC UPC fiber connectors. UPC type connector boot usually is black color, APC boot is green color. We supply the FC fiber connectors which are compatible with IEC 61 754-143 standards, these products are good compatibility to use in telecommunications, CATV, LAN, WAN, medical and on test and measurement fiber optic devices.

The screw coupling keeps end-face contact stable when the rack is vibrating or when technicians work on neighboring ports, which is why FC stayed the default on test sets, monitoring gear and older carrier equipment. FC needs the alignment key to seat in the adapter slot before the nut is tightened. Cross-threading a keyed FC is the single most common cause of high loss on an FC link.

Single-mode fiber carries one propagation mode in a 9 µm core, so pulse spreading stays low and the link budget is set by loss rather than dispersion. Use it for access, metro and long-haul spans, for PON distribution and for anything that has to survive a future speed upgrade.

Key Benefits

Supplied as FC Connector SM, so the part you receive matches the designation you ordered against
Single Mode at 9/125 µm: Use it for access, metro and long-haul spans, for PON distribution and for anything that has to survive a future speed upgrade.
Consistent ferrule bore and geometry so polish recipes stay stable
Full connector range from one supplier and one order
Component-level pricing for volume assembly
Bulk packing suited to production rather than single repairs

Problems It Solves

Repair benches held up waiting for a single component type
Ferrule bore variation that shifts the polish result between batches
Housings that do not seat consistently in a given adapter brand
Spring force drift that changes physical contact under the same mating load

Application Scenarios

Optical test and measurement ports
Producing patch cords and pigtails on an assembly line
Re-terminating damaged cords on a repair bench
Integrating optical ports into OEM equipment
Practice terminations in a fiber training program

Who It Is For

Cable assembly houses producing their own cords and pigtails
OEM equipment makers integrating optical interfaces
Repair and refurbishment benches
Training centers and technical schools

Compared With Other Options

SC	SC seats faster with a push-pull motion; FC holds up better where the cabinet vibrates or ports get bumped
ST	ST twists on with a bayonet in a quarter turn; FC's threaded nut takes longer but resists loosening
Multimode version	Multimode is cheaper to drive over short in-building distances but cannot carry the reach or the upgrade headroom of single mode.

Use Guide

Handling FC Connector SM

Before You Order

Match ferrule bore to the fiber you are terminating
Follow the epoxy manufacturer's mix ratio and cure schedule
Polish in stages, inspecting the end face between stages

In Service

Verify geometry on an interferometer before the assembly is released
Measure insertion loss and return loss on the finished assembly
Store unused bodies capped and dry

FAQ

Questions About FC Connector SM

What do you need from us to quote FC Connector SM?

The quantity, the destination and anything that has to match on your side: connector and polish at each end, fiber mode and core size, and length where the item is an assembly. If you are matching a part you already buy, send the sample and we will quote against it.

Can FC Connector SM be supplied with a different connector interface?

Yes. FC (Ferrule Connector) is what this designation carries, and the same family is stocked across the other mainstream connector standards. Tell us the port you have to mate with and we will confirm the equivalent part.

Is FC Connector SM available in the other fiber mode?

This item is single mode. Single-mode alignment tolerance is tight. End-face cleanliness matters more here than on any multimode link. The corresponding version in the other fiber mode is available; confirm the installed plant at both ends before ordering.

What are the minimum order quantities at component level?

Component-level items are normally sold in bulk packs. Send us the connector type and your annual usage and we will quote the pack size and price break that fits.

Do connectors ship as complete kits?

Yes, the body is supplied with its crimp sleeve and strain-relief boot so an assembly bench has everything needed apart from fiber, epoxy and polishing film.
