Product Overview

SC Bare Adapter is part of the bare adapter range built by Ever Expresslink Limited in Ningbo, China. It is built on the SC (Subscriber Connector) interface.

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.

It is one of 7 items in this range. A typical application is fiber training and practical assessment. What the range is built to give you there: reusable across many fibres in a single session.

The problem it addresses is terminating a fiber purely to verify continuity, then cutting the connector off. A practical note that applies across this range: clean the guide bore between fibres. Specifications for a particular configuration are confirmed on the quotation rather than assumed from the designation.

Key Benefits

Supplied as SC Bare Adapter, so the part you receive matches the designation you ordered against
Compact enough to live in a splicing kit
Square and standard body versions for different panel and bench mounts
Measure without spending a connector and a termination cycle
Reusable across many fibres in a single session

Problems It Solves

Slow fault-finding on a partly built link
Damaged fiber from improvised clamping methods
Test kits that cannot reach bare fiber in a splice tray
Needing a measurement on fiber that has not been terminated yet

Application Scenarios

FTTH terminal boxes and splice closures
Fiber training and practical assessment
Continuity checking before a splice closure is sealed
Power measurement on an unterminated distribution cable
Laboratory characterisation of fiber samples

Who It Is For

Laboratories characterizing fiber samples
Training programs teaching splice verification
Maintenance teams fault-finding on a partly built link
Splicing crews verifying continuity before closing a tray

Use Guide

Handling SC Bare Adapter

Before You Order

Cleave the fiber square with a precision cleaver before insertion
Clean the fiber with lint-free wipe and solvent
Insert to the stop and close the clamp without forcing it

In Service

Treat the reading as indicative rather than as a certified link measurement
Release the clamp before withdrawing the fiber to avoid scoring it
Clean the guide bore between fibres

FAQ

Questions About SC Bare Adapter

What do you need from us to quote SC Bare Adapter?

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 Bare Adapter 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.

Do I still need to cleave the fiber?

Yes. The adapter aligns the fiber but cannot fix a bad cleave. A square, clean cleave is what makes the reading meaningful.

What fiber sizes does a bare adapter accept?

Versions are available for 250 µm coated fiber and for 900 µm tight-buffered fiber. Confirm which one your splice tray presents before ordering.

Is a bare adapter measurement as accurate as a terminated one?

It is repeatable enough for continuity and relative loss checks, which is what a splicing crew needs. For certified link measurements, terminate properly or use a reference-grade test cord.
