MTP Loopback

MTP loopback

Our MTP loopback line covers 8, 12, 16 and 24 fiber interfaces in single-mode and multimode versions, all enclosed in rugged housings built for daily use.

During diagnostics the loopback reveals transmit power faults, receiver sensitivity problems, port mapping errors and polarity mistakes across QSFP+, QSFP28, CXP and CFP interfaces. Loss options are available to match normal or stressed channel conditions.

MTP Loopback Features

  • Sealed rugged housing, no exposed fibers
  • Controlled, repeatable insertion loss
  • Pin and polarity options matched to the port
  • Suitable for QSFP+, QSFP28, CXP and CFP
  • Long service life in burn-in environments
  • Verified end-face geometry

Typical Applications

  • Switch and router port commissioning
  • Parallel link fault isolation
  • Polarity verification in MTP cabling
  • Receiver sensitivity measurement
