2G6
OR4160 -FA Application 4 Optical to electrical conversion of four return path signals in hybrid fiber coax (HFC) networks
Features 4 Four independent optical receivers 4 Bandwidth 5…160 MHz 4 Each of the 4 receivers can be switched to the -20dB test port on front 4 Pilot tone and optical input power controlled AGC to keep the RF level independent from the optical input power 4 Wide optical input power range 4 Each receiver section can be disabled separately 4 Optical power detection on all inputs 4 Sleep mode for the unused receiver 4 RS485 remote supervision and control interface 4 SC/APC or E2000 connector as standard 4 Requires 1 slot in 2G6 rack
