Table 52.     Optical Parameters for Cisco 4-Gbps CWDM SFP Modules

Parameter	Symbol	Minimum	Typical	Maximum	Units	Notes and Conditions
Transmitter center wavelength	Lambda_c	(x – 6)	x	(x + 6)	nm	Available center wavelengths are 1470, 1490, 1510, 1530, 1550, 1570, 1590, and 1610 nm
Side-mode suppression ratio	SMSR	30	–	–	dB	–
Transmitter optical output power	Pout	1.0	–	5.0	dBm	Average power coupled into single-mode fiber
Receiver optical input power (BER <10–12 with PRBS 2-23-1)	Pin	-15.7	–	0.0	dBm	140°F (60°C) case temperature
Link budget	–	17.8	–	–	dB
Receiver optical input wavelength	Lambda_in	1450	–	1620	nm	–
Transmitter extinction ratio	OMI	4	–	–	dB	–

Note:       

●      In typical point-to-point deployments, all wavelengths have a minimum reach of 24.8 miles (40 km).

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

●      When shorter distances of single-mode fiber are used, you may need to insert an inline optical attenuator in the link to avoid overloading the receiver.

●      Up to 24 Cisco 4-Gbps CWDM SFP Transceivers are supported in a single Cisco MDS 9000 Series switching module.

●      When interoperating a Cisco 4-Gbps CWDM SFP Transceiver with a Cisco 1/2-Gbps CWDM SFP Transceiver, you must manually configure the port speeds on the Cisco 4-Gbps CWDM SFP Transceiver to 1 or 2 Gbps.
