7.2.3 Parameter Description
Transmit optical power
Output optical power of an optical module when it is working properly. When two optical
modules are connected, the transmit optical power of one end must be within the range
of receive optical power on the other end.
Receive optical power Average input optical power that the receiver of an optical module can receive within a
range of bit error rate (BER = 10
-12
). The upper limit of this parameter is the overload
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.
Maximum receiver
sensitivity
Minimum average input optical power that the receiver of an optical module can receive
within a range of bit error rate (BER = 10
-12
). When two optical modules are connected,
the maximum receiver sensitivity on one end determines the minimum value of transmit
optical power on the other end.
Overload optical power Maximum average input optical power that the receiver of an optical module can receive
within a range of bit error rate (BER = 10
-12
). When two optical modules are connected,
the overload optical power on one end determines the maximum transmit optical power
on the other end.
Extinction ratio 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.
