SFP (Small Form Factor Pluggable) is a compact, hot-swappable transceiver module that converts electrical signals into optical signals (and vice versa), enabling long-distance communication between devices. One of the main advantages of SFP modules is their hot-swappable nature, which allows them to be inserted or removed without powering down network devices.
The biggest difference between 100M module, Gigabit module and 10G optical module is the transmission rate. The packaging form of 100M and Gigabit optical modules is SFP, and the packaging of 10G optical modules is SFP+ and XFP. The transmission speed of 100M module is: 155Mb/s and 622Mb/s;
40G optical modules can provide high-density and low-power 40G Ethernet high-speed interconnection for data centers, high-performance computing networks, and telecom operators. Common packaging forms of 40G optical modules are CFP, QSFP, and QSFP+ optical modules.
Generally, optical modules have two ports, TX is the transmitting port and RX is the receiving port; while single-core optical modules use WDM technology to achieve bidirectional transmission of optical signals on one optical fiber. Single-core optical modules have many nicknames: single-fiber bidirectional optical modules, BIDI optical modules, single-mode single-core optical modules, single-core bidirectional optical modules, single-fiber bidirectional transmission modules, etc.
For enterprises with high demand for network bandwidth, such as finance and high-frequency trading, as the business expands, the surge in concurrent network traffic will inevitably lead to network congestion and have a great impact on the business, so bandwidth upgrades are inevitable.
