In a 25G dark fiber service offering, we needed modules that could guarantee performance over long distances. The LS-BL273125-40I’s 40km reach and APD receiver make it ideal for this use case. We tested with 25G traffic generators and saw no packet loss or jitter issues. The DOM data is accurate and stable, which helps our operations team monitor the links. Our customers see full 25G performance, and we’ve had zero complaints since deploying these modules.

We use these 25G BiDi optical modules in an industrial environment with extreme temperature swings. The operating range of -40 to 85°C is critical for our outdoor cabinets and unconditioned telco rooms. We monitored the modules through a full seasonal cycle: from -35°C winter nights to +70°C internal enclosure temps in summer. The link remained stable, with no flaps or SFP alarms. The TX power and receiver sensitivity stayed within spec, and the DDM temperature readings were accurate compared to our external sensors. For 25G SFP28 BiDi in harsh environments, this is one of the most reliable options we’ve tested.

We integrated these modules into a 25G ring topology for a municipal fiber network. The ring uses 25G BiDi links of varying reaches (10km, 20km, 40km) to connect different nodes. The LS-BL273125-40I handles the longest spans without problems. The DDM alarms allow us to detect fiber degradation early, and the industrial temperature rating ensures stability in outdoor cabinets. The 25.78Gbps data rate supports both Ethernet and CPRI traffic, which is exactly what we need for our converged network.
