Cisco Receive-Only WDM GBIC [Cisco Transceiver Modules]

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.

Table 1 describes the electrical power interface details, and Table 2 describes optical parameters.

Table 1 Electrical Power Interface Data

Parameter	Symbol	Minimum	Typical	Maximum	Units
Supply current	Is		250	300	mA
Surge current	ISurge			+30	mA
Input voltage	Vmax	4.75	5.0	5.25	V

Table 2 Optical Parameters

Parameter	Symbol	Minimum	Typical	Maximum	Units	Notes/Conditions
Receiver optical input power (BER <10^-12 with PRBS 2^-7-1)	Pin	-29.0		-7.0	dBm	1.25 Gbps
Receiver optical input wavelength	lin	1450*		1620	Nm	See Note a)

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.
