GIGALIGHT 400G transceivers offer customers a wide variety of super high-density 400 Gigabit Ethernet connectivity options for data centers, enterprise networks, and service provider applications. Here is a list of FAQs about our new generation of 400G transceiver modules.

Q: What 400G transceivers are available from GIGALIGHT?

A: GIGALIGHT supports a full range of 400G optical transceivers in QSFP-DD form factors, 400G AOCs and DACs, and 400G breakout cables. The tables below summarize the 400G connectivity options GIGALIGHT supports.

Q: What are the benefits that GIGALIGHT 400G transceivers can offer?

A: GIGALIGHT 400G transceivers help cloud operators, service providers, and enterprises to achieve higher bandwidth at lower cost and power per gigabit. Key benefits of GIGALIGHT 400G transceivers include:

  1. With QSFPDD form factors to meet your diverse needs of ramping up to 400G transmission.
  2. SiPhbased technology used on some GIGALIGHT 400G transceivers for lower power & cost and higher density.
  3. Compliant with QSFPDD MSA and IEEE 802.3bs, and tested in host devices for proven interoperability, superior performance, quality, and reliability.
  4. Compatible with mainstream brands such as Cisco, Juniper, Arista, Dell, Mellanox, etc.
  5. Simplify your network by reducing the number of optical fiber links, connectors and patch panels by a factor of 4.

Q: What are the application scenarios of GIGALIGHT 400G transceivers?

A: 400G QSFP-DD transceiver modules are the backbone of high-performance 400G networks. GIGALIGHT 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 shortreach 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: GIGALIGHT 400G transceivers accord with a range of certifications for optical transceivers including ISO 9001:2015, RoHS, REACH, CB, RCM, FCC certificate (EAC Certificate). Rest assured that our products will meet essential quality and safety requirements.

Q: Are GIGALIGHT 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 GIGALIGHT OSFP module into a 400G QSFP-DD port, or GIGALIGHT 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 GIGALIGHT 400G OSFP modules must be used.

Q: Can I return the product or get a refund?

A: GIGALIGHT 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 GIGALIGHT receives and inspects the returned items.
