Excellent receiver sensitivity on high-attenuation fiber paths! We installed this BiDi SFP optical module on an older single-mode fiber run with high cumulative attenuation and numerous field splices along a 62km path. The high-sensitivity receiver locks onto the 1490nm signal effortlessly, and our bit error rate testing reported zero defects over a continuous 24-hour test period, proving the overall quality of the hardware.

Excellent product, held up at customs for days. The optics themselves are top-tier and the DDM readings are incredibly accurate. The only downside was the package getting stuck in local customs for almost three days, which delayed our scheduled network deployment.
