The application of 100G light modules, with the accelerated development of industries such as the Internet, cloud computing, and big data, 100G products have become wider and wider, and long -distance demand has increased. For long-range transmission application scenarios, the traditional solution needs to use DWDM devices to increase the transmission distance. Its networking is complicated, and additional equipment costs are required to maintain high cost. Reduce maintenance costs. Now, we introduce the 100G light module for everyone. 1) What is 100G light module

In simple terms, 100G light module is a light module with a rate of 100G

2) Types of 100G light module

According to the different packaging methods, the 100G optical modules mainly include CFP / CFP2 / CFP4, CXP and QSFP28. Among them, CFP / CFP2 / CFP4 and CXP are encapsulation methods of early 100G light modules. QSFP28 is the new generation of 100G light module module The packaging method, and now it has become the mainstream packaging of the 100G light module. The principle of 100G QSFP28 light module is similar to the QSFP + light module, and the 100G light signal is transmitted by 4 × 25 GBPS.

3) Standards for 100G light modules

Since the advent of 100G networks, IEEE, MSA Industry Alliance and other institutions have formulated multiple standards for the 100G light module. Among the many standards, the PSM4 and CWDM4 standards formulated by the multi -source protocol (MSA) industry organization are more suitable for the mainstream 100G QSFP28 light module on the market.

4) Parameters of 100g light module

There are many very important optoelectronic technical parameters, but we only need to understand several important parameters;

One: Central wavelength: unit nano (NM);

Two: Transmission rate: refers to the number of Bit (BIT) that transmits data per second, unit BPS;

3: Transmission distance: refers to the distance that the light signal does not require relay can be directly transmitted, the unit kilometers (also known as kilometer, KM);

There are other laser categories, losses and scattered, transmitting light power and receiving sensitivity, optical fiber interface and use temperature, etc., so that you can better choose the product that suits you.

100g light module advantage

1. The CFP optical module supports the wavelength of the full C -band, which can complete the link detection. The common light dual binary and adjustment pattern ODB is selected. The convenience arrangement, the power consumption is less than 24W.

2. The volume of the CFP2 optical module is one -half of the CFP. Its integration is twice the CFP. It can complete the stable acceptance of the stable input range according to SOA, support the comprehensive CFP optical module, and its power consumption is low. In 9W.

3. The volume of the CFP4 optical module is one -half of the CFP2, and its integration is twice the CFP2, and the density of the front port port is doubled compared to CFP2. The CFP4 optical module MSA protocol, supporting the same rate as CFP2 as CFP2S, the transmission power has increased significantly, but the power consumption has decreased significantly, only about half of the original, and the price is lower than that of CFP2. In addition, the CFP4 optical module is in the form of 4*25. Through 4 25G channels, 100G transmission is completed. The transmission power is higher and the stability is stronger.

4. The packaging style of the QSFP28 light module is smaller than the CFP4 light module. The power consumption of the QSFP28 optical module does not exceed 3.5W. The use of the QSFP28 optical module can be directly upgraded from 25G to 100G through 40G, and the cost is lower.

With the rapid development of the optical communication industry, the application of 100G light modules is becoming more and more wide. The 100G QSFP28 optical module and 100G CFP/CFP2/CFP4 optical module can meet the corresponding standards. The selectivity is wide, stable, and cost -effective. It also provides comprehensive network system solutions to help users build low -cost benefits High network system. Welcome to our optoelectronics.
