Build dependable long-reach 10 GbE links with a CWDM SFP+ transceiver tuned for 1350 nm operation over single-mode fiber. Rated for 20 km, it is suited to network segments where distance and optical consistency matter more than short-range convenience. DOM support helps infrastructure teams verify transceiver health, monitor optical levels, and isolate issues without guesswork. The LC duplex connector fits standard SMF plant, making this module a practical choice for backbone extensions, inter-building runs, and aggregation paths that need predictable performance. Cisco compatibility adds deployment flexibility for teams that want to standardize optics without redesigning the physical layer. For procurement and engineering teams, the value is clear: long reach, diagnostic visibility, and a compact SFP+ footprint that supports higher-confidence network builds.
