Product Overview
SC/PC Adapter MM is part of the fiber adapter range built by Ever Expresslink Limited in Ningbo, China. It is built on the SC (Subscriber Connector) interface.
We supply SC fiber optic adapters; these products are various types including single mode and multimode, zirconia sleeve and bronze sleeve, simplex and duplex versions. Standard female to female SC fiber optic adapter and hybrid SC fiber optic adapters are available. Typical SC fiber optic adapters are with plastic housing and for single mode SC UPC it is blue color, single mode SC APC it is green color, multimode SC UPC is beige color. We also supply the metal housing SC fiber optic adapters. Most of these adapters come with ceramic sleeves, while there are bronze sleeve SC adapters which are generally multimode types.
SC Fiber optic adapter features: Compact design Telcordia, ANSI, TIA/EIA, NTT and JIS compliance High precision alignment Low insertion and return loss and back reflection Choice of metal or plastic housing, mount styles & flange options SC Fiber optic adapter applications: CATV Telecommunication networks Local Area Networks (LANs) Metro networks Data processing networks Industrial, military and medical
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.
Multimode fiber carries many modes in a 50 or 62.5 µm core, which makes alignment and coupling far more forgiving over short distances. Use it inside buildings, data halls and campus backbones where reach is short and low-cost VCSEL transceivers do the work.
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 Adapter MM, 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.
- Multimode at 50/125 µm or 62.5/125 µm: Use it inside buildings, data halls and campus backbones where reach is short and low-cost VCSEL transceivers do the work.
- Color coding by polish type, so APC ports are visible at a glance
- Simplex, duplex and quad bodies for different port densities
- Precision alignment sleeve sized for the ferrule and fiber mode
Problems It Solves
- 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
- Dust entering open ports between commissioning and service turn-up
Application Scenarios
- FTTH terminal boxes and splice closures
- Stocking spare ports for emergency restoration
- 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
Who It Is For
- Data-center cabling contractors
- FTTH terminal box and closure assemblers
- Maintenance teams replacing worn ports
- Distributors stocking a full adapter matrix

- Mating force and alignment verification
- Dust cap fitting and packing
Quality Control
- Sleeve inner diameter sampled per lot
- Insertion loss checked with reference cords on sample units
- Repeated mating durability test on samples
- Panel fit verified against the stated cut-out dimension
- Visual check for sleeve seating and housing flash
Customization Options
- Ceramic or bronze sleeve
- Flanged, flangeless or square mount
- Simplex, duplex or quad body
- Housing color to your polish convention
- Private-label bagging for distributors
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. |
| Single mode version | Single mode costs more at the transceiver but carries reach and upgrade headroom that multimode cannot. |
Handling SC/PC Adapter MM
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/PC Adapter MM
What do you need from us to quote SC/PC Adapter MM?
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 Adapter MM 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 Adapter MM available in the other fiber mode?
This item is multimode. Core size has to match end to end. Mixing 62.5/125 and 50/125 in one channel costs several dB at the junction. The corresponding version in the other fiber mode is available; confirm the installed plant at both ends before ordering.
How do I choose between flanged and flangeless?
It depends on the panel. Flanged adapters mount through a rectangular cut-out with screws, flangeless versions clip into a smaller aperture. Measure the existing cut-out before ordering replacements.
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.
