Product Overview
SC Withdrawal Adapter is part of the fiber adapter range built by Ever Expresslink Limited in Ningbo, China. It is built on the SC (Subscriber Connector) interface.
SC pairs a 2.5 mm ferrule with a square push-pull housing that clicks into the adapter and releases by pulling the body straight back. 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 18 items in this range. A typical application is populating an optical distribution frame during a build-out. What the range is built to give you there: dust caps fitted so ports stay clean until they are commissioned.
The problem it addresses is sleeve wear after repeated matings, which shows up as slowly rising loss. A practical note that applies across this range: keep dust caps on both sides until the port is commissioned. Specifications for a particular configuration are confirmed on the quotation rather than assumed from the designation.
Key Benefits
- Supplied as SC Withdrawal Adapter, so the part you receive matches the designation you ordered against
- Precision alignment sleeve sized for the ferrule and fiber mode
- Flanged and flangeless versions to suit existing panel cut-outs
- Dust caps fitted so ports stay clean until they are commissioned
- Color coding by polish type, so APC ports are visible at a glance
Problems It Solves
- Mixed single-mode and multimode adapters in the same field with no visual difference
- Loose panel mounting that lets the adapter move when a cord is pulled
- Sleeve wear after repeated matings, which shows up as slowly rising loss
- Panel cut-outs that do not match the adapter flange being supplied
Application Scenarios
- Enterprise backbone links
- Populating an optical distribution frame during a build-out
- Replacing worn ports found during a maintenance sweep
- Building faceplates and terminal boxes on an assembly bench
- Creating temporary cross-connects on a test bench

Handling SC Withdrawal Adapter
Before You Order
- Confirm the panel cut-out before ordering flanged or flangeless
- Keep dust caps on both sides until the port is commissioned
- Clean both ferrules before every mating, not only the first one
In Service
- Replace rather than clean a sleeve that has visible wear
- Keep APC and UPC ports physically separated and color coded
- Torque panel screws evenly so the body does not sit skewed
Questions About SC Withdrawal Adapter
What do you need from us to quote SC Withdrawal 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 Withdrawal 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.
Can an adapter be used to join UPC to APC?
No. Mating UPC to APC leaves an air gap that costs a large amount of loss and can damage both end faces. If you have to cross polish types, the correct part is an attenuator or a converter assembly, not an adapter.
How often should adapters be replaced?
Replace when a port shows rising loss that cleaning does not fix, or when the sleeve is visibly worn. In a heavily re-patched field this is a consumable, not a permanent fixture.
Do adapters come with dust caps?
Yes, adapters are supplied with caps on both sides. Leave them in place until the port is actually patched, because an open port in a dusty building will need cleaning before first use.
