We compared this module against other 155M BiDi SFPs on the market. The DFB laser maintained a tighter wavelength stability over temperature, and the PIN receiver had a lower noise floor. At 80 km, the signal-to-noise ratio was superior, allowing reliable communication even with marginal fibre quality. The firmware is fully MSA compliant, so no proprietary handshake issues arose. For long‑haul 155M applications, this is a top-performing optical transceiver.

Field deployment involved connecting two industrial sites separated by 70km of underground fibre. The SFP operated without a single flap through seasonal temperature swings from -10°C to 55°C. DOM reported stable TX power (-3dBm) and RX power (-27dBm) throughout the test period. The integrated digital diagnostics helped us quickly identify a loose connector during installation. This module is a workhorse for critical infrastructure backbones.

We deployed these SFP modules for a 155Mbps SCADA backhaul over a single-strand SMF. The BiDi design cut our fibre usage in half, and the Simplex LC connector simplified patching. With TX at -2dBm and RX sensitivity at -32dBm, the link budget supported our 76km run with multiple patch panels. The module performed consistently across humidity and vibration tests. It’s a no‑nonsense solution for legacy industrial networks.
