FAQ:

What is 1.25 g SFP?

1.25G-SFP-2D 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 13 dB, with in most cases is enough to reach about 2 km distance.
 

What is compatible with 1.25 g SFP?

1.25G-SFP-10D SFP is fully compliant to SFP Multi Source Agreement INF-8074i. Consequently, it means that module is compatible with 80% of networking equipment, where is not implemented a special algorithm for protection against third party modules.

1.25G Dual Fiber SFP transceiver module
The SFP transceivers are high-performance, cost-effective modules supporting dual data-rate of 1.25Gbps/1.0625Gbps. The transceiver consists of three sections: a laser transmitter, a photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit. All modules satisfy class I laser safety requirements. The transceivers are compatible with SFP Multi-Source Agreement (MSA) and SFF-8472. For further information, please refer to SFP MSA.
