Combines with the FG-750 Node iOLM as part of the first practical FTTx line quality assessment solution from the node.

Key features

  • Combines OTDR wavelength(s) 1625 and/or 1650 nm with OLT/ONT/Tx/Rx traffic signals up to 1614 nm
  • 24-channel WDM kit
  • Dense construction, only 1U height, less than 300 mm deep
  • SC-APC front access ports, left to OLTs, right to network/ODN
  • Pigtailed at the rear for direct connection to test equipment, saving one jumper and one connection–3 m long
  • Rear pigtail models for SC, LC, 12-fiber MTPs and 8-fiber MPOs


TAM Couples OTDR to Line

Test access module (TAM) is the common and standard name given to a fiber-optic coupling element, which is used in remote testing and monitoring applications to combine the OTDR signal with traffic.

The device used to perform this function is typically a coupler. Some are broadband-type, others are WDM-type or wavelength-division multiplexers, which are spectrally sensitive combiners.

24-WDM TAM Kit

This kit allows 24 transmit/receive ports to be coupled with an OTDR test signal with the lowest loss possible, compared to other tapping techniques. These WDMs also isolate Tx/Rx circuits from any OTDR signal coming back from the network in excess of 30 dB.

MTP/MPO 48-Channel Fanout or Patch Panel (Without WDM)

If you own EXFO test equipment or opt for an optical switch terminated with 12-fiber MTPs or 8-fiber MPOs, and need an SC-APC termination, EXFO also offers the same footprint and assembly, without the WDMs. Similarly to the TAM kits, 3 m-long multifiber pigtails at the rear can connect to the front/rear of the test equipment that is terminated with a multifiber connector. This is used to transfer from multifiber to single-fiber cabling, close to the test equipment.
