This SFP transmits at a centre wavelength of 1470 nm and is colour-coded gray; its transmit window runs 1466 to 1477 nm, using the tolerance of 4 nm below to 7 nm above centre. Gigabit Ethernet runs at 1.25 Gbps full duplex, and Fibre Channel at 1.06 and 2.12 Gbps full duplex. Optical link budget is 29 dB for Gigabit Ethernet and 28 dB for Fibre Channel.
The network side is a dual LC/PC connector on single-mode fibre; APC patch cords are not supported. Average transmit power is 0 to 5.0 dBm, and the receiver accepts -29.0 to -7.0 dBm at 1.25 Gbps. Operating temperature is -5 to 70 C on a 3.3 V supply (3.1 to 3.5 V), drawing 220 mA typical and 300 mA maximum. It is one of eight wavelengths on the ITU-T G.694.2 CWDM grid, spaced 20 nm apart from 1470 nm to 1610 nm.
It follows IEEE 802.3z for 1000BASE-X and FC-PI, and is a Class I laser product. The SFP is hot-swappable. Its receiver accepts light from 1450 to 1620 nm. A longer-wavelength sibling in the same family is the 1490 nm CWDM SFP, which is coded differently and shares the optics above.
More transceivers are under Cisco interface cards.
