MTP Loopback

MTP loopback

MTP loopback modules route the transmit lanes of a parallel optical port straight back into its receive lanes inside a sealed housing. Engineers use them to verify transceivers, switch ports and cabling segments without a remote partner device.

Versions are available for 8, 12, 16 and 24 fiber MTP interfaces in single-mode and multimode grades. During testing the loopback reveals transmit power problems, receiver sensitivity faults, port mapping errors and polarity mistakes in 40G QSFP+, 100G QSFP28, CXP and CFP environments. The enclosed design protects the internal fiber so the module survives daily use in production lines, data centers and field maintenance kits.
