Channel 35 on the ITU grid belongs to the DWDM-SFP-4931, a pluggable optic in the Cisco interface cards range that emits at 1549.32 nm. Its optical port is a dual LC/PC type, matched to single-mode fiber plant.
On the receive side the input power window runs from -28.0 to -9.0 dBm when the link is power-limited and from -22.0 to -9.0 dBm when it is noise-limited. The receiver can be damaged by an input level of +5 dBm.
Operating temperature spans 0 to 70 C, while storage is rated for -40 to 85 C. The module weighs typically less than 75 g, and its supply current is 200 mA typical and 300 mA maximum on a 3.3 V rail.
Traffic types covered are Gigabit Ethernet and Fibre Channel, each at 1 Gbps or 2 Gbps. The optical link budget is 28 dB, and transmit power is 0 to 4.0 dBm, while patch cords fitted with APC connectors are not supported.
