When it comes to 100G optical module, you may first think of the earliest CFP optical module. However, with the development of the network, CFP optical modules have gradually failed to meet the requirements of high density and low power consumption in data centers. Under such a development trend, 100G QSFP28 optical module came into being. 100G QSFP28 LR4 optical module is one of the models of QSFP28 optical module, which is widely used in 100G Ethernet. It uses WDM technology to multiplex optical signals with different wavelengths from four optical fiber channels into one optical fiber for transmission, which meets the requirements of long-distance transmission in data centers. So what's the difference between it and CFP LR4 optical module? How to apply 100G QSFP28 LR4 optical module? The following Moduletek will give you a detailed answer.
100g the difference between qsfp28lr4 optical module and CFP LR4 optical module.
100G QSFP28 LR4 optical module and CFP LR4 optical module are both 100G single-mode optical modules, with wavelength 13 10nm and maximum transmission distance 10km. What is the difference between them?
1. Their volumes are different.
The volume of 100G QSFP28 LR4 optical module is smaller than that of CFP LR4 optical module.
2. The power consumption is different.
The power consumption of 100G QSFP28 LR4 optical module is lower than that of CFP LR4 optical module, which is generally between 6 ~ 6 ~ 24W, while that of 100G QSFP28 LR4 optical module is generally within 3.5W
3. Their application ranges are different.
CFP LR4 optical module supports dual rate and can be applied to 40G and 100G Ethernet, while 100G QSFP28 LR4 optical module can only be applied to 100G Ethernet. Since the size of 100G QSFP28 LR4 optical module is smaller than that of CFP optical module, 1000 is generally used in high-density wiring environments such as data centers.
4. The price is different.
At the same transmission distance, the cost of CFP LR4 optical module is slightly higher than that of 100G QSFP28 LR4 optical module. For details, please contact 0755-25867895.
