SMUGDESK 2Pack OM3 12Core MPO/UPC Female Loopback Tester Cable
A two-pack of 12-core OM3 multimode MPO/UPC female loopback cables for 40G and 100G QSFP port testing and network diagnostics
- Cost-effective 2-pack for multiport testing and backup
- 12-core high-density MPO/UPC female matches QSFP ports
- OM3 50/125µm multimode fiber for 40G and 100G networks
- Precise loopback enables quick port diagnostics and fault detection
- Wide compatibility with 40G/100G switches routers and optical modules
2Pack 12Core MPO Loopback Tester
This 2Pack of OM3 multimode loopback cables provides twelve cores in each MPO/UPC female connector for 40G and 100G network testing. They are built for data centre engineers and installers who need to verify QSFP and QSFP28 module ports quickly during deployment or maintenance.
Sustained Signal Integrity
The 50/125µm fibre maintains stable optical transmission across all twelve cores during extended test sessions, allowing repeated port diagnostics and transceiver verification without signal degradation. Each tester returns the transmit path directly to the receive path so that hardware performance and system stability can be confirmed under continuous load.
Passive Thermal Profile
As passive fibre components they draw no power and generate no heat or noise, making them suitable for dense rack environments where active test gear would add thermal load. The compact MPO/UPC female form factor fits directly into module ports without adapters, keeping insertion loss low during normal use.

Questions about this item
Does the 12Core MPO/UPC loopback generate noticeable heat or draw extra power during continuous 40G/100G testing?
The passive OM3 multimode loopback contains no active electronics, so it produces no heat and consumes no power during extended QSFP port diagnostics.
What equipment must already be in place for the 12Core MPO/UPC female tester to function?
A 40G or 100G switch, router or optical module with a QSFP/QSFP28 port is required to mate with the MPO/UPC female connector.
Can the OM3 50/125m loopback validate legacy 10G or 25G SFP+ ports in the same rack?
The 12Core MPO/UPC interface is built for QSFP/QSFP28 transceivers; it does not connect to SFP+ or other legacy form factors.
