About optical transceiver modules
Optical transceiver modules (also called fiber transceiver modules) transmit signals over optical
fibers and are suitable for long distance transmission.
The following information explains the major specifications of a fiber transceiver module.
Data rate
Data rate is the number of bits transmitted per second. Data rate is typically measured in Gigabits
per second (Gbps).
Transmission distance
The transmission distance of optical transceiver modules is divided into short and long-range types.
Typically, a distance of 2 km (1.24 miles) or below is short-range type and a distance of 10 km (6.21
miles) is long-range type.
Transmission distances supported by optical transceiver modules are mainly limited by signal
attenuation and dispersion suffered during the transmission of fiber signals over fibers.
•
Signal attenuation occurs because of absorption, dispersion, and leakage over the media as
light travels through optical fibers. This attenuation increases in direct ratio to transmission
distance.
