optical power and the lower limit is the maximum receiver sensitivity. When two optical
modules are connected, the receive optical power on one end determines the range of
transmit optical power on the other end.
Minimum average input optical power that the receiver of an optical module can receive

the maximum receiver sensitivity on one end determines the minimum value of transmit
optical power on the other end.
within a range of bit error rate (BER = 10
the overload optical power on one end determines the maximum transmit optical power
on the other end.
Minimum ratio of the average optical power with signals transmitted against the average
optical power without signals transmitted in complete modulation mode. The extinction
ratio indicates the capability of an optical module to identify signal 0 and signal 1. This
parameter is a quality indicator for optical modules. Optical modules with a large
extinction ratio may not have good quality. Qualified optical modules should have an
extinction ratio complying with IEEE 802.3.
