With the development of optical communication technology, the market size of the optical module has continued to increase, and the 400G QSFP-DD packaging has become one of the most popular optical modules of large-scale data centers with the advantages of low power consumption, small volume, and high rate.

At present, the types of 400G QSFP-DD optical modules on the market include 400G SR8, 400G DR4, 400G FR4, 400G LR4, 400G LR8, etc.

In this blog, let's take a look at 400G QSFP-DD FR4. ETU-LINK's 400G QSFP-DD FR4 optical module can effectively increase network capacity and meet user needs. It is the preferred solution of Mid -length transmission in 400G data center. Now, let's take a look at the 400G QSFP-DD FR4 optical module.

Product Features

400G QSFP-DD FR4 is the optical module of the channel full dual-work and transmission,using hot-inserted QSFP-DD packaging and a dual LC interface. The maximum transmission distance can be reached by up to 2km by single -mode fiber . The maximum power consumption is less than 10W, Complying with QSFP-DD MSA and IEEE 802.3CU 400GBase-FR4 Ethernet standard.

Working Principle

The 400G QSFP-DD FR4 optical module uses 4 CWDM wavelengths of non-refrigeration EML laser. The transmission rate of a single fiber 400G is reached through Demux/MUX. This module converts the 8th road 53.125GB/S telecommunications signal into a light signal of 106.25GB/s, and reused it into a single road for 425GB/s light transmission. Similarly, it uses a 425GB/s input optical signal to unbract as a 4 -channel light signal and converts it into an 8 -channel output electrical signal on the receiver.

Application scenarios

As the demand for data centers on a higher speed rate module is becoming more and more strong, 400G PAM4 modulation products have become the trend of the future data center market. The 400G QSFP-DD FR4 optical module is used as a 400G QSFP-DD optical module Mid -length transmission solution, Widely using in 400G Ethernet, data centers and cloud computing scenarios.
