This fixed-wavelength SFP emits at 1538.19 nm, ITU channel 49 on the 100 GHz grid. The 100 GHz grid puts channel 49 at 1538.19 nm, with channel 50 at 1537.40 nm on one side and channel 48 at 1538.98 nm on the other. It is one of 40 fixed channels, numbered 20 to 59, and this one is the 1538.19 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. The optical link budget is 28 dB.
It uses a dual LC/PC connector; only PC or UPC patch cords are supported, not APC. Transmit power is 0 to 4.0 dBm average into single-mode fibre, with the centre wavelength held to within 100 pm of nominal. Receiver input is -28.0 to -9.0 dBm when power-limited, and the receiver damage threshold is +5 dBm.
For a coarse-grid alternative at 1490 nm, see the 1490 nm CWDM SFP. Operating temperature is 0 to 70 C, with storage from -40 to 85 C.
