Product Overview

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

SC fiber products are commonly seen and SC fiber optic connectors are found on many equipment and cable assemblies. SC fiber optic connector features its easy operation, good accuracy and low cost. Below is a drawing for the simplex SC fiber optic connector.

SC is square shape design, with push-pull latching mechanism, its keyed, molded housing provide optimum protection. SC fiber connector adopt 2.5mm ceramic ferrule. SC fiber products are available by both single mode and multimode versions, single mode SC have two types, one is SC UPC and the other is SC APC, multimode only has SC UPC connectors. According to the industrial practice, single mode SC UPC connector is blue color, single mode SC APC connector is green color, multimode SC UPC is beige color. Each type has duplex models. We supplied all common types SC fiber optic connectors, they are fully compliant to the TIA/EIA-568A and Fiber Channel standards, Huihong SC fiber products are competitive price and good reliability.

It is the workhorse of FTTH and passive optical distribution: a technician can seat a port blind, inside a closure, wearing gloves, without rotating anything. SC bodies clip together into duplex pairs. Check polarity before you clip, because a reversed duplex clip is easy to build and hard to spot in a cabinet.

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.

PC is the baseline physical-contact polish, with a lighter dome than UPC. It appears on older plant and on multimode links where return loss is not the limiting factor.

Key Benefits

Supplied as SC/PC Connector SM, so the part you receive matches the designation you ordered against
PC end face: It appears on older plant and on multimode links where return loss is not the limiting factor.
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.
Component-level pricing for volume assembly
Bulk packing suited to production rather than single repairs
Compatible with standard epoxy and polish workflows

Problems It Solves

Sourcing separate parts for each connector type from separate suppliers
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

Application Scenarios

FTTH terminal boxes and splice closures
Re-terminating damaged cords on a repair bench
Integrating optical ports into OEM equipment
Practice terminations in a fiber training program
Building custom assemblies for a one-off project

Who It Is For

Repair and refurbishment benches
Training centers and technical schools
Distributors supplying assembly consumables
Cable assembly houses producing their own cords and pigtails

Quality Control

Ferrule bore diameter sampled from each ceramic lot
Housing dimensional checks against the applicable standard
Spring force verified on sample units
Trial termination and polish from each production lot
Packing count and kit completeness verified before dispatch

Customization Options

Single-mode or multimode ferrule bore
Ferrule length and boot style

Compared With Other Options

LC	LC is half the footprint and doubles port density; SC is easier to handle in a crowded closure
FC	FC's threaded nut resists vibration; SC is faster to patch and re-patch
APC version	APC adds an eight degree angle so reflections leave the core, which matters on PON, CATV and RF-over-glass paths. It is not interchangeable with this part.
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 SC/PC 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 SC/PC Connector SM

What do you need from us to quote SC/PC 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 SC/PC Connector SM be supplied with a different connector interface?

Yes. SC (Subscriber 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 SC/PC 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.

Can I get single-mode and multimode bore in the same connector type?

Yes. Ferrule bore is specified per order, and single-mode and multimode versions of the same connector family are available together.

Are the housings compatible with other brands of adapter?

The housings are built to the published dimensions of each connector standard, so they mate with standard-compliant adapters. If you are matching a specific installed adapter, send us the part and we will confirm before you commit to volume.
