CWDM-SFP-1530 Cisco 1530 nm CWDM SFP Transceiver

This SFP transmits at a centre wavelength of 1530 nm and is colour-coded green; its transmit window runs 1526 to 1537 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. 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. 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. On short single-mode runs an inline optical attenuator may be needed to keep the receiver from overloading. Side-mode suppression is at least 30 dB and extinction ratio at least 9 dB.

Dispersion penalty over 100 km is up to 2 dB at 1.25 Gbps and up to 3 dB at 2.12 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. The SFP is hot-swappable. A shorter-wavelength sibling in the same family is the 1510 nm CWDM SFP, which is coded differently and shares the optics above.

Other transceivers are listed in Cisco interface cards.
