Product Overview

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

Small form-factor transceivers are built around it, so LC is what a data-center or an access switch presents to you whether you wanted it or not. The latch is small and breaks if the cord is pulled sideways out of a dense panel. Use a boot or a push-pull tab on panels packed to 48 ports and above.

It is one of 7 items in this range. A typical application is laboratory characterisation of fiber samples. What the range is built to give you there: square and standard body versions for different panel and bench mounts.

The problem it addresses is slow fault-finding on a partly built link. A practical note that applies across this range: cleave the fiber square with a precision cleaver before insertion. Specifications for a particular configuration are confirmed on the quotation rather than assumed from the designation.

Key Benefits

Supplied as LC Square 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

Test kits that cannot reach bare fiber in a splice tray
Needing a measurement on fiber that has not been terminated yet
Terminating a fiber purely to verify continuity, then cutting the connector off
Slow fault-finding on a partly built link

Application Scenarios

Enterprise switch uplinks
Continuity checking before a splice closure is sealed
Power measurement on an unterminated distribution cable
Laboratory characterisation of fiber samples
Fault localisation during a restoration

Who It Is For

Test engineers measuring unterminated cable
Laboratories characterizing fiber samples
Training programs teaching splice verification
Maintenance teams fault-finding on a partly built link

Use Guide

Handling LC Square 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 LC Square Bare Adapter

What do you need from us to quote LC Square 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 LC Square Bare Adapter be supplied with a different connector interface?

Yes. LC (Lucent 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 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.

How many times can one adapter be reused?

They are designed for repeated insertion across a working session and beyond. Replace when the clamp no longer holds the fiber firmly or the guide bore shows wear.

Which connector types are available?

SC, FC, ST and LC interfaces are the common ones, in both standard and square-body form. Tell us your test set's port type and we will match it.
