Cisco - Module transmetteur SFP

The Cisco GLC-BX40-D-I SFP operates on a single strand of standard SMF. The GLC-BX40-D-I SFP also supports digital optical monitoring (DOM) functions according to the industry-standard SFF-8472 multisource agreement (MSA). This feature gives the end user the ability to monitor real-time parameters of the SFP, such as optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage.
