1. Types of 10G optical modules
A 10G optical module refers to an optical module that can send and receive 10G data signals per second. According to different packages, 10G optical modules can be divided into XENPAK optical modules, X2 optical modules, XFP optical modules and SFP + optical modules.
2. Types of 40G optical modules
40G optical module refers to an optical module with a transmission rate of 40Gbps. CFP and QSFP are its main packaging forms, and 40G QSFP + optical module is one of the more widely used ones.
3. Types of 100G optical modules
According to different packaging methods, 100G optical modules mainly include CFP / CFP2 / CFP4, CXP and QSFP28. Among them, CFP / CFP2 / CFP4 and CXP are early 100G optical module packaging methods, and QSFP28 is a new generation 100G optical module Packaging method, and now has become the mainstream package of 100G optical module. The principle of the 100G QSFP28 optical module is similar to that of the 40G QSFP + optical module. It uses a 4 × 25 Gbps method to transmit 100G optical signals.

1. Application of 10G optical module
10G optical modules are mainly XFP optical modules and SFP + optical modules. Among them, XFP optical modules are relatively large due to their early appearance, and SFP + optical modules are upgraded versions of SFP optical modules. Many advantages, such as strong sex, have been widely used in data center networks.
Today, the 10G network technology and market are mature. The solution for 10G data centers is usually 10G switches with SFP + 10 Gigabit optical modules and LC fiber patch cords. Switches with different rates should match the optical modules with corresponding rates.
2. Application of 40G optical module
The main package type of the 40G optical module is QSFP +. This compact hot-swappable optical module has four transmission channels, and the data rate of each channel is 10Gbps, and this optical module conforms to SCSI, 40G Ethernet, 20G / 40G Infiniband and other standards, it greatly meets the market demand for high density and high speed.
In order to meet the demand for high-speed Ethernet and cloud computing, virtual data centers and other services, the transformation of the communication transmission network from 10G to 40G is unstoppable. In addition to adding equipment and optical cables to achieve greater bandwidth and throughput, increasing port density is also a widely accepted method for data centers to transition to 40G. 40G data center solutions usually consist of 40G switches with 40G QSFP + optical modules, MTP / MPO Fiber Jumper.
3. Application of 100G optical module
The main package type of 100G optical module is QSFP28. This QSFP28 optical module supports 4 × 25G data transmission mode, and is highly favored by data center users because of its high port density, low power consumption and low cost.
Facing the explosive growth of data services, the demand for big data transmission in the backbone network has rapidly increased. The construction of 100G, a mainstream global operator, has started. The solution for 100G data centers is usually 100G switches with 100G QSFP28 optical modules and MTP / MPO fiber jumpers.
