Optical transceivers

Optical transceivers play a pivotal role in data transmission, and they are categorized based on various factors. One primary classification is by transmission rates, which include 400G, 100G, 40G, 25G, 10G, 1G, and 100M optical modules.

Another significant classification is by their encapsulation types. As the transmission rate of an optical module increases, so does its structural complexity. Based on encapsulation, they are differentiated into SFP, SFP+, XFP, SFP28, QSFP+, CXP, CFP, QSFP28, and QSFP-DD modules.

A notable feature of these optical modules is that they are all hot swappable, ensuring flexibility and ease of use.
