Fiber-optic receiver: LWL-EHR

Signal Processing
Fiber-optic transmitter/receiver with outdoor box for
interference-free transmission of square-wave signals
Fiber-optic transmitter/receiver with outdoor box
Features
–– Transmission length up to 1500 m
–– Converting standard square-wave signals into optical
signals
–– Reconversion of optical signals into electrical signals
and generation of status signals
–– Transmission error detection via checksum (CRC)
–– High-precision transmission of signals
(Jitter <100 ns)
–– Constant delay time <20 μs
–– Automatic channel switchover in realtime upon
failure of one fiber-optic channel
–– Outdoor box with protection IP 66, IP 67
