There are many types of optical modules, each suitable for different application scenarios and requirements. The following are some common optical module types:
Optical transceiver module (Transceiver Module):
SFP (Small Form-Factor Pluggable): A small, pluggable optical module, widely used in standards such as Gigabit Ethernet (GbE) and 10 Gigabit Ethernet (10GbE).
SFP+ (Enhanced Small Form-Factor Pluggable): Similar to SFP, but supports higher data transmission rates and is mainly used for high-speed networks, such as Ten Gigabit Ethernet (10GbE) and Forty Gigabit Ethernet (40GbE).
QSFP (Quad Small Form-Factor Pluggable): Integrated four-channel optical module for high-density, high-bandwidth applications, such as Forty Gigabit Ethernet (40GbE) and One Hundred Gigabit Ethernet (100GbE).
XFP (10 Gigabit Small Form Factor Pluggable):
A small optical module used in 10GbE networks, which is more common in data centers and enterprise network environments.
GBIC (Gigabit Interface Converter):
An earlier large-scale optical module suitable for applications such as Gigabit Ethernet (GbE) and Fast Ethernet. Due to its large size, it is gradually replaced by small modules such as SFP.
CFP (C Form-Factor Pluggable):
A large optical module used in high-speed networks such as Hundred Gigabit Ethernet (100GbE) and Four Hundred Gigabit Ethernet (400GbE).
CXP:
An optical module used in high-speed networks, typically used for high-density, high-bandwidth connections such as Hundred Gigabit Ethernet (100GbE) and Four Hundred Gigabit Ethernet (400GbE).
XENPAK, XPAK, X2:
These are some of the earlier large optical modules used in 10GbE networks, but due to their larger size, they are gradually replaced by small modules such as XFP.
Each optical module type has its specific specifications and applicable scope. Choosing the appropriate optical module depends on network requirements, data transmission rate, and application environment.
