With the development of optical communication technology, the scale of optical transceiver market is growing, and 400G QSFP-DD package has become one of the most popular optical transceivers for hyperscale data centers with the advantages of low power consumption, small size and high rate.
At present, the types of 400G QSFP-DD optical transceivers in the market are 400G SR8, 400G DR4, 400G FR4, 400G LR4, 400G LR8, etc.
In this issue, let’s take a look at 400G QSFP-DD FR4 first. ETU-LINK’s 400G QSFP-DD FR4 optical transceiver products can effectively enhance network capacity and meet users’ needs, which is the preferred solution for 400G data centers in medium and long distances. Next, let’s learn more about the 400G QSFP-DD FR4 optical transceiver.
Product Features
The 400G QSFP-DD FR4 is a channel full-duplex transceiver optical transceiver in a hot-swappable QSFP-DD package, compliant with QSFP-DD MSA and IEEE 802.3cu 400GBASE-FR4 Ethernet standard, with dual LC optical ports, transmission distance up to 2km over single-mode fiber (SMF), and maximum power consumption less than 10W.
Working Principle
The 400G QSFP-DD FR4 optical transceiver uses four uncooled EML lasers at CWDM wavelengths, which are DEMUX/MUXed to achieve a single-fiber 400G transmission rate. The transceiver converts eight 53.125Gb/s electrical signals into four 106.25Gb/s optical signals and multiplexes them into a single circuit for 425Gb/s optical transmission. Similarly, it demultiplexes a 425Gb/s input optical signal into a 4-channel optical signal and converts it into an 8-channel output electrical signal at the receiving end.
Application Scenario
With the increasing demand for higher speed optical transceivers in data centers, 400G PAM4 modulated products become the future trend in the data center market. 400G QSFP-DD FR4 optical transceivers are widely used in 400G Ethernet, data centers and cloud computing scenarios as long distance transmission solutions in 400G QSFP-DD optical transceivers.
