Keep optical links serviceable with a compact module built for fast replacement and dependable fiber connectivity. The CyberData 011236 is a hot-pluggable SFP transceiver intended for single-mode optical networking, making it a practical fit for environments where uptime and maintenance speed matter. Its LC duplex interface and SFP form factor support straightforward integration into compatible network equipment. For teams managing fiber runs, the ability to replace a module without disrupting the entire system can reduce maintenance windows and simplify spares planning. That is especially valuable in access layers, aggregation points, and other locations where fiber continuity is critical. This module is designed for optical network and data networking applications, with support for single-mode fiber and a nominal 1310 nm wavelength in the source data. It is the kind of component chosen when the network needs precise, serviceable connectivity rather than a generic transceiver. For infrastructure teams, that means a cleaner path to stable fiber links and less time spent on avoidable downtime.
