There are two types of the receiver module: Standard Input Optical Receiver and
Low Input Optical Receiver.
Low Input Optical Receiver.
The optical input range for the low input receiver is 0.1 w to 0.63 w (-10 dBm to -2
dBm). Compared to the standard input optical receiver (the optical input range is -6
dBm to +2 dBm (0.25 w to 1.58 w)), the low input optical receiver can work with
lower optical input level, in order to support fiber deep applications.
