Network test access points (TAPs) are hardware tools that allow you to access and monitor your network. The modular passive fiber chassis system supports 1G, 10G, 25G, 40G and 100G network speeds. 

This high density and high performance monitoring solution accommodates growing data center and enterprise needs for Ethernet networks up to 100G. The passive fiber modular chassis system features a scalable design allowing you to meet the demands of today’s and tomorrow’s network, while supporting the investment in existing monitoring tools.

FMC Chassis accommodates 16 to 24 network TAP modules, based on configuration (24 LC TAP Modules, 16 MPO/MTP® TAP Modules, 16 BiDi LC TAP Modules)

  • Durable, all steel construction for chassis and TAP network modules
  • No power, no heat, no IP address, no MAC address – 100% passive
  • Customize network TAPs to your networks needs
  • Change network TAP modes on-the-fly or in the future
  • Mix and match modules by media and/or speeds
  • Supports single-mode: OS1/OS2 and multi-mode: OM1/OM2/OM3/OM4/OM5 media for long range and short range environments
  • OM5 fiber supports SWDM (Short Wavelength Division Multiplexing), this enables 40/100G-SR to be run on LC-duplex fibers giving networks a clear path to migrate to 40/100G
  • Supports Cisco BiDirectional optical technology
  • Supports split ratios of: 90/10, 80/20, 70/30, 60/40, 50/50, 33.3/33.3/33.3
  • Supports Passive Replication
  • Designed, manufactured and supported in the United States
  • Made, tested and supported in the USA
