Micro-OTDR Fiber Fault Monitor

New Micro-OTDR Technology Lets You Quickly and Accurately Detect Faults

Avoid outages caused by fiber faults by Early Detection

More and more companies are using fiber these days, but aren't taking the necessary precautions to avoid costly outages. The key to avoiding outages caused by fiber faults is early detection. With advanced notification of broken links and faults, you'll instantly get the upper hand in preventing outages.

Micro OTDR in action
Traditionally, many fault detectors were plagued with poor performance and operational problems. First, they would occupy an entire optical shelf, which is inefficient. Secondly, they were sensitive to the noise caused by the return reflections.

Micro OTDR

However, a new "reflection immune" design overcomes these previous limitations by using special firmware to make these single fiber, single wavelength (SFSW) SFP Transceivers immune to reflections. This transceiver is also capable of CWDM data transport in normal use. You won't have to dedicate an entire fiber for monitoring, nor will you sacrifice a CWDM channel, so you'll have more optical fibers for revenue generation.

The bottom line is: you're instantly notified of faults in your fiber transports. This saves you operational expense dollars and helps you quickly get back online during outages (such as disaster-recovery situations).

  • Monitors optical fiber links for fault detection
  • Pulses of light measure distance to reflection of broken fiber
  • Reflection immune operation (RIO)
  • Single mode fiber (SM)
  • Minimum 20 dB optical link budget for data transport
  • Minimum 55 db dynamic range for micro-OTDR
  • Up to 27 dB optical link budget
  • Full-dupliex, single wavelength (1471nm to 1611nm)
  • Reduces Mean-Time-To-Repair (MTTR)
  • SNMP alarm reporting
  • Alarm notifications via email, text messaging, or voice dial-outs

T/Mon collects SNMP traps from micro-OTDRs and displays fiber cuts on an intuitive multi-user map. Fiber cuts are generally best displayed as line segments. When fiber is cut, the segment can change color and blink. Drilling down to SNMP trap detail will tell you the OTDR-measured ranges.
