Description Precision Optical Transceivers PRE-SFP10G-LRM, 10Gb/s SFP (SFP+), transceivers support 10-Gigabit Ethernet links up to 220 m at 1310 nm wavelength over Multimode fiber. PRE-SFP10G-LRM module electrical interface is compliant with SFI electrical specifications. The transmitter converts 10Gb/s serial PECL or CML electrical data into serial optical data compliant with the 10GBASE-LRM standard. The receiver converts 10Gbit/s serial optical data into serial PECL/CML electrical data. Rx_LOS when high indicates an optical signal level below that specified in the relevant standard. This typically indicates to missing, broken cables or a disabled, failing or a powered off transmitter at the far end of the system. System Application:
