MPO loopback modules fold the transmit lanes of a parallel optical port back into its receive lanes inside a sealed housing. Engineers use them to prove transceivers, switch ports and cabling segments without a partner device at the far end.
The housing protects the looped fibers from dust, bending and handling damage, giving the module a long service life in burn-in racks and field kits. Pin configuration and polarity are selected to match the port under test, and custom loss values can be built for receiver stress testing.
MPO Loopback Features
- 8, 12, 16 and 24 fiber MPO loopback configurations
- Single-mode OS2 and multimode OM3/OM4 versions
- Sealed housing with no exposed fibers or splices
- Controlled, repeatable insertion loss options
- Pin and polarity choices matched to the port under test
- Suitable for QSFP+, QSFP28, CXP and CFP interfaces
Typical Applications
- Optical transceiver production and burn-in testing
- Switch and router port validation during commissioning
- Parallel link troubleshooting in live data centers
