  • 1.25G-SFP-550D is Multi-Vendor MSA Compatible SFP (Small Form factor Pluggable) Transceiver, operating over Double Fiber Multi-Mode Fiber (MMF) optical cable. It has minimum guaranteed optical budget of 7.5 dB, with in most cases is enough to reach about 550 m distance.

    However, distance is just indicative parameter calculated for comfort of identification. Eventually we calculate distance taking in account minimal optical budget and average attenuation of optical cabling in industry. This transceiver use top quality VSCEL Laser transmitter with operating at nominal wavelength 850 nm. and 850 nm. PIN Photodiode receiver.

    It support DDM/DOM optical diagnostics, with provide diagnostic information about the present operating conditions. 1.25G-SFP-550D operates in Standard 0°-70°C temperature range and has Double LC interface.
