We deployed this LS-DW4910-80C 10G SFP+ module on a 70km inter-building link through a passive DWDM MUX. The -1 to +5dBm TX output with the high-sensitivity APD receiver gave us plenty of margin above the -23dBm sensitivity limit. Real-time DDM readings make span loss monitoring very easy. Highly recommended for long-range networking.

Installed these C49 1538.19nm DWDM transceivers into edge aggregation switches for backhaul. Even over varying ambient rack temps between 25°C and 55°C, the transceiver maintained stable optical output without bit errors. Total throughput stays pinned at 10.7Gbps line rate. Very impressed with the build quality and heat dissipation. :-)
