This fixed-wavelength SFP emits at 1538.98 nm, ITU channel 48 on the 100 GHz grid. The 100 GHz grid puts channel 48 at 1538.98 nm, with channel 49 at 1538.19 nm on one side and channel 47 at 1539.77 nm on the other. It is one of 40 fixed channels, numbered 20 to 59, and this one is the 1538.98 nm channel in that span of 1530.33 to 1561.42 nm. It carries Gigabit Ethernet or Fibre Channel at 1 Gbps and 2 Gbps. Transmit power is 0 to 4.0 dBm average into single-mode fibre, with the centre wavelength held to within 100 pm of nominal.
It uses a dual LC/PC connector; only PC or UPC patch cords are supported, not APC. Receiver input is -28.0 to -9.0 dBm when power-limited, and the receiver damage threshold is +5 dBm. Spectral width is 0.2 nm at most, side-mode suppression is at least 30 dB, and extinction ratio is at least 8.2 dB.
A coarse-grid 1490 nm option is the 1490 nm CWDM SFP. The body measures 8.5 x 13.4 x 56.5 mm and typically weighs under 75 g.
Further transceivers are available from Cisco interface cards.
