Functions
An optical module provides optical-to-electrical and electrical-to-optical conversion functions.
It is connected to an optical fiber to transmit signals.
Appearance
Optical modules can be classified into the following types by encapsulation type: small
form-factor pluggable (SFP), enhanced SFP (eSFP), small form-factor pluggable plus (SFP+),
10-GB small form-factor pluggable transceiver (XFP), and quad small form-factor pluggable
plus (QSFP+). The optical module appearance varies according to the encapsulation type.
Figure 2-3 shows an SFP/SFP+ optical module. Figure 2-4 shows a QSFP+ optical module.
