Overview
A copper-based, pluggable fiber-optic transceiver is a compact, hot-swappable device
that both transmits and receives functions in full duplex mode. It includes optical
transmitter and receiver pairs. The pair number depends on the transceiver type, and the
pairs can be with or without a clock and a data recovery integrated circuit.
If a fiber-optic transceiver is part of the installed configuration, it receives optical signals
from the client equipment or network fiber at the wavelength that is specific for the
transceiver. Then the transceiver performs optical-to-electrical conversion and transfers
the electrical signals to the relevant circuits on the board for further processing and
transmission. Conversely, the fiber-optic transceiver receives electrical signals from the
relevant circuits and performs electrical-to-optical conversion. Next it transmits the
optical signals at the wavelength that is specific for the transceiver over optical fibers to
the client or network interfaces.
Modules with interchangeable interfaces use pluggable transceivers. The system uses
these types of pluggabletransceivers:
l Quad SFP (QSFP) transceivers for applications with data rates up to 4x xxGb/s
