Spec sheet
Spec sheet
Overview
Purpose-built construction OTDRs for everyday field testing in any access network. With an intelligent Optical Link Mapper (iOLM) application for both singlemode and multimode testing, this is the most automated and intelligent troubleshooting tool for FTTA, LAN and data centers.
FTBx-720D - LAN/WAN access OTDR

Key features

  • Dynamic range of up to 38 dB in singlemode and 30 dB in multimode
  • Quad singlemode/multimode version
  • FTTx in-service testing at 1650 nm with optional in-line GPON/XGS-PON power meter
  • Swap-Out connector, replaceable whenever necessary for optimal performance over time without undue service cost and downtime
  • iOLM-ready: one-touch multiple acquisitions, with clear go/no-go results presented in a straightforward visual format
  • OTDR, light source and power checker through single port to optimize the fiber handling process.

Applications

  • Access network construction and troubleshooting
  • FTTx/PON testing though splitters (up to 1x32)
  • FTTx service activation: GPON, EPON, XGS-PON, 10GE EPON
  • Central office link certification
  • Data center and private networks
  • LAN/WAN characterization
  • Fronthaul/backhaul
