MetroWAVE-TAP-SM: Passive Optical Fibre TAP

Network Monitor Schematic

MetroWAVE-TAP-SM Network Monitor Schematic

  • 24 Port Single-mode in-line Optical Fibre TAP
  • Supports up to 24 duplex tapped network connections in 1U rack space
  • Supports 10Mb, 100Mb, 1G and 10Gb data traffic
  • Full line rate throughput
  • Monitor ports available for non-evasive system debug
  • Unpowered passive device for highest possible reliability

The MetroWAVE-Tap-SM is a high port density Single-mode Optical TAP, providing non-invasive monitoring for up to 24 duplex (i.e. separate Transmit/Receive channels) optical network connections within a compact 1U sized unit.

The MetroWAVE-Tap-SM passes uninterrupted data between front-panel input/output fibre ports, whilst accurately duplicating all network traffic to rear-panel ‘monitor ports’. Per-port network speeds of 10Mb, 100Mb, 1Gb and 10Gb are supported.

The MetroWAVE-Tap-SM operates by performing a 2-way passive optical split of each input fibre port at the front panel, with one path being returned to the front panel pass-through output port and the other path being directed to the rear panel monitor port. A 50/50 optical power split is normally provided between pass-through and monitor ports, optimised for short-haul fibre applications, however other split ratios are available on request.

The full MetroWAVE family comprises CWDM Multiplexer and Optical Tap products based on passive optical technology, with no optical-electrical-optical conversion. All units are unpowered and contain no moving parts, for maximum robustness and reliability.
