DEM-311GT 1000BASE-SX Multi-Mode Transceiver is designed for
business environments with high-speed network transmission. It
supports a data rate of 1Gbps and 550m transmission distance. The
transceiver consists of a VSCEL laser transmitter, a PIN photodiode
integrated with a TIA, and an MCU control unit. All modules meet
class I laser safety requirements. Hot pluggable design can easily
switch out transceivers while the power is on, facilitating network
maintenance and minimizing downtime.
