Data Sheet

Cisco Receive-Only WDM GBIC

The Cisco Receive-Only Wavelength-Division Multiplexing (WDM) Gigabit Interface Converter (GBIC) pluggable allows cable service providers to build optimized transport networks for video-on-demand applications. The Cisco Receive-Only WDM GBIC can be used as a pluggable receiver on any unidirectional link in a CWDM and/or DWDM transport network.

Main features of the Cisco Receive-Only WDM GBIC

  • GBIC can be used as receiver for all wavelengths supported by Cisco CWDM and Cisco DWDM pluggable transceivers
  • GBIC provides high receive sensitivity
  • GBIC is cost optimized for unidirectional links (no transmitter)
  • Hot-swappable input device that plugs into Gigabit Ethernet GBIC ports or slots of a Cisco switch/router, linking the port with the network
  • Cisco Receive-Only WDM GBIC can be used and interchanged on a wide variety of Cisco products and can be intermixed in combinations of 1000BASE-SX, 1000BASE-LX/LH, or 1000BASE-ZX on a port-by-port basis

Performance

  • Gigabit Ethernet 1.25-Gbps full-duplex links
  • Receiver Sensitivity -29 decibels (db)

Platform Support

The Cisco Receive-Only WDM GBIC is supported across a variety of Cisco switches, routers, and optical transport devices. For more details see the document Cisco Receive-Only WDM GBIC Compatibility Matrix.

Note:    Parameters are specified over temperature and at end of life unless otherwise noted.

a) Receiver sensitivity is -25.0 dB for 1270-1450 nm window

Note:    When shorter distances of single-mode fiber are used, it might be necessary to insert an in-line optical attenuator in the link to avoid overloading the receiver.

Warranty

  • Standard warranty: 90 days
  • Extended warranty (option): Available under a Cisco SMARTnet® support contract for the Cisco switch or router chassis
