The AFBR-57R5APZ is environmental requirements. AFBR-57R5APZ devices hot-pluggable, allowing the module to be installed while provide real-time access to transceiver internal supply the host system is operating and on-line. Upon insertion, voltage and temperature, allowing a host to identify the transceiver housing makes initial contact with the potential component compliance issues. Received host board SFP cage, mitigating potential damage due optical power is also available to assess compliance of to Electro-Static Discharge (ESD). a cable plant and remote transmitter. When operating out of requirements, the link cannot guarantee error free Digital Diagnostic Interface and Serial Identification transmission.
