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.
