MetroWAVE Fibre TAP

MetroWAVE is a series of passive CWDM devices which can dramatically simplify your network infrastructure. Metrodata Optical Fibre TAPs are unpowered passive devices for highest possible reliability that support full line rate throughput supporting network speeds from 10Mb to 10Gb and provide monitoring per port.

  • 24 Port Single-mode or Multimode 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 Fibre TAP is a high port density Single-mode or multimode 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 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 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.

What is a TAP?

A TAP (Traffic Analysis Point or Traffic Access Port) is a hardware device that provides access to traffic flowing on a physical connection between two or more points within a network. The TAP usually is located in the link between network devices, so the connection from point A connects to the TAP and then from the TAP to point B. The TAP provides a mirrored output of the data flowing between to network ports.

Three important features of a TAP:

  • The TAP provides a mirrored output of the data passing through the device
  • The data passing through the TAP cannot be modified or degraded by the monitor
  • The TAP doesn't affect the passing data, so monitoring is done without disruption, requires no power and no electrical components.

When installed correctly a TAP can provide access to data flowing across the network, does not allow data to be modified or corrupted and do not represent a point of failure.

Why use a TAP?

A TAP is used for network monitoring and analysis, it provides the necessary access to the data for network monitoring equipment. Often when a device begins to fail, corruption to data is often the start, however network protocols can mask problems by automatically retrying on errors. A TAP allows monitoring to detect network errors and potentially warn about failing devices, a TAP is not only important for monitoring but can provide details not available from other network components - Link Layer access. Many network devices strip away Link Layer information which often contains error information - the information accessed through a TAP presents all layer data, from Physical to Application.
