SMUGDESK 2Pack 16Core MPO/UPC Female OM3 50/125 Loopback Adapter

SKU CH-ZK9V-QG9KA

Two-pack of 16-core MPO/UPC female loopback adapters using OM3 50/125 µm fibre for 40G/100G QSFP testing

  • 2-pack supply streamlines multi-port testing and data centre deployment
  • 16-core MPO/UPC female design matches high-speed QSFP ports precisely
  • OM3 50/125 µm multimode fibre supports stable 40G/100G transmission
  • Loopback function enables fast port diagnostics and QSFP transceiver verification
  • Plug-and-play compatibility with 40G/100G data centre and telecom systems

2Pack 16Core MPO Loopback Adapter

This 2Pack provides 16Core MPO/UPC female loopback adapters built for 40G/100G network environments. They suit data centre engineers, telecom installers and enterprise network teams who need quick port validation on QSFP modules. Each adapter returns the optical signal to its source so technicians can verify transceiver health and link integrity during deployment or troubleshooting. The OM3 multimode 50/125m fibre supports the high bandwidth these speeds demand.

Check QSFP Port Gender and Fibre Type

Before ordering confirm that the target QSFP ports accept an MPO/UPC female connector and that the installed cabling uses OM3 multimode 50/125m fibre. The adapters only function when the transceiver and patch cables share the same core size and polish type. They are not suitable for single mode links or for equipment that requires an MPO male interface. Verify the port density and lane count match the 16core layout to avoid misalignment during testing.

Compact PlugAndPlay Build for Daily Rack Use

The adapters arrive as a ready to use pair with no drivers or configuration required. Their low profile moulding sits flush against dense QSFP cages so adjacent ports remain accessible during multiport sweeps. The UPC polish keeps insertion loss low for repeatable loopback measurements across 40G and 100G lanes. Technicians can carry the 2Pack in a tool pouch, plug in, run diagnostics and move to the next rack without extra cables or cleaning kits.

Questions about this item

What comes in the 2Pack and do I need any extra cables or transceivers?

The 2Pack supplies two 16Core MPO/UPC female loopback adapters ready for immediate testing; QSFP transceivers and patch cables are separate purchases.

Which version should I pick for 40G or 100G QSFP ports?

Both adapters are OM3 50/125 multimode and built for 40G and 100G networks, so either unit works for those speeds.

What does the 16Core OM3 rating mean when I plug it into a live QSFP link?

The 16Core OM3 50/125 fiber returns the optical signal directly back into the port, letting you verify 40G or 100G link integrity without a far-end device.
