Operating a regional ISP network requires getting maximum performance out of every single-strand fiber lease. We installed these 20km BiDi SFP28 optical modules across multiple remote aggregation nodes to double our available backhaul bandwidth. Compatibility was flawless across our multi-vendor router fleet, with all boards loading the SFP28 MSA compliant settings instantly. Even over our longest 18.5km span, the DFB laser punched through attenuation effortlessly. Internal temperatures stayed around 40°C under heavy traffic, making this an ultra-reliable optics transceiver for high-capacity telecom links.
