SMUGDESK 5Pack SC/UPC OM4 Multimode Duplex Fiber Loopback Adapter 50/125m
Five-pack of SC/UPC OM4 multimode duplex loopback adapters for 50/125 µm fibre testing and port diagnostics
- Five-pack bulk supply simplifies multi-port testing and spare stock
- OM4 multimode 50/125 fibre supports high-speed short-distance transmission
- Standard SC/UPC connector works with switches, routers and test equipment
- Loopback function enables quick port diagnostics and fault detection
- Compact plug-and-play design suits enterprise networks and lab scenarios
Five-pack loopback adapters for fibre testing
This set contains five SC/UPC duplex loopback plugs built with OM4 multimode 50/125µm fibre. They are intended for technicians who need to verify multiple ports quickly in data centres, enterprise networks or laboratory environments.
Check connector type and fibre grade before ordering
Ensure the equipment under test uses SC/UPC interfaces and is designed for OM4 multimode fibre. The adapters will not mate with LC, ST or FC connectors, nor are they suitable for single-mode links that require a different core size.
Compact plug-and-play construction for daily use
Each plug is a small, self-contained unit that inserts directly into a transceiver or panel port without tools. The duplex housing keeps transmit and receive fibres aligned, so repeated insertions during routine maintenance or fault finding remain reliable.

Questions about this item
What comes in the 5-pack and do I need any extra cables or tools?
The pack contains five SC/UPC duplex loopback adapters with OM4 50/125 µm fiber. They plug directly into SC ports on switches, transceivers or test gear — no extra cables or tools required.
Should I pick OM4 50/125 µm or another grade for my short-reach multimode links?
OM4 50/125 µm is the grade supplied; it matches OM4 multimode infrastructure and transceivers used for high-speed short-distance runs. Choose this version when your network specifies OM4 fiber.
What does the 50/125 µm figure tell me about loss and distance in a live link?
The 50/125 µm core/cladding size identifies OM4 multimode fiber, which supports the higher bandwidth and reach specified for OM4 short-range optics in your equipment.
