Selection Notes

SFP993-1LH is the long-haul single-mode transceiver in the SFP993 family: choose it once the fiber run exceeds the 10 km limit of the standard single-mode variant, up to a 40 km reach. Its higher 4.5 dB minimum link attenuation means it needs a fiber-optic budget with enough loss in the path, unlike the shorter-reach variants, which tolerate near-zero attenuation. Its -4.7 to 4 dBm output and -14.1 dBm receiver sensitivity set the practical loss budget, so verify connector and splice losses against these figures before specifying the run.
