In the context of the continuous progress of Internet technology and the increasing demand for network transmission speed, 400G FR4 optical module came into being and has become the key to meet the needs of high-speed network transmission in the future. This article describes the features, advantages, and application scenarios of the 400G FR4 optical modulein detail.
I. Working principles of the 400G QSFP-DD FR4 optical module
The 400G QSFP-DD FR4optical module is an optical transceiver module designed for 2km optical communication applications and complies with the 100G Lambda MSA standard. The module can convert 8 53.125Gb/s electrical signals into 4 106.25Gb/s optical signals, and reuse them into one optical signal for 425Gb/s optical transmission.
Similarly, it can optically demultiplexed 425Gb/s input to a 4-channel signal, converting it to 8-channel output electronic data at the receiving end. It is designed to meet the harshest external operating conditions, including temperature, humidity and electromagnetic interference. The module uses a duplex LC interface that provides a very high level of functionality and functional integration, accessible via a two-wire serial interface.

FAQs About 400G Transceivers
Q: What are the application scenarios of 400G transceivers?
A: 400G QSFP-DD transceiver modules are the backbone of high-performance 400G networks. 400G transceivers can be used in various scenarios. Generally speaking, it depends on the connection distance you want to cover. For example, you can use 400G DAC and AOC cables for short-reach connections between ToR switch and server. For 2km to 10km data center interconnection connections, QSFP-DD FR4 or LR4 modules are better high-quality and economical choices.
Q: What quality certifications do you have for your 400G transceivers?
A: 400G transceivers accord with a range of certifications for optical transceivers including ISO 9001:2015, RoHS, REACH, CB, RCM, FCC, and Russian TR CU certificate (EAC Certificate). Rest assured that our products will meet essential quality and safety requirements.
Q: Are 400G transceivers compatible with Cisco or Juniper brands?
A: Many of our 400G transceiver modules are compatible with Cisco, Juniper, Arista, Dell, Mellanox, etc. You can always ask for a compatibility test before the purchase to check whether our transceiver is compatible with your devices. If you’re deploying a larger network or upgrading your current data center architecture, compatible transceiver modules may come in handy as they can be immediately installed without compatibility problems and fit right into your data center infrastructure.
Q: Can I plug OSFP module into a 400G QSFP-DD port, or QSFP-DD module into an OSFP port?
A: No. OSFP and QSFP-DD are two physically distinct form factors. If you have an OSFP system, then 400G OSFP modules must be used. If you have a QSFP-DD system, then 400G QSFP-DD modules must be used.
Q: Can 100G QSFP module be plugged into a 400G QSFP-DD port?
A: Sì, un modulo di transceiver 40/100GQSFP può essere inserito in una porta QSFP-DD in quanto QSFP-DD è retro-compatibile con i moduli QSFP, QSFP+ e QSFP28. Quando si utilizza un modulo QSFP in una porta QSFP-DD 400G, la porta QSFP-DD deve essere configurata per la velocità dati di100G.
Q: Cosa devo fare se non so quale modulo è il più adatto per me?
A: Our dedicated customer support offers 24/7 technical assistance. If you have any questions about our transceiver modules, such as how to select the right 400G optical transceiver for your switches, how to choose between different form factors, what to do when typical technical glitches occur, or how to place an order, don’t hesitate to contact our tech support.
Q: Can I return the product or get a refund?
A: Walsun wants you to be thrilled with our 400G transceiver modules. However, if you need to return an item or ask to get a refund, we’re here to help. For all 400G transceiver modules, DAC & AOC cables, and breakout cables, you have 30 calendar days to return an item from the date you received it, which means the request must be submitted within the return/exchange window. Refunds will be processed after receives and inspects the returned items.
