400G QSFP-DD/QSFP112/OSFP Transceivers

400G QSFP-DD / OSFP Transceivers selection guide
PHILISUN 400G QSFP-DD / OSFP Transceivers are optical transceiver options for AI, HPC and high-density data center spine-leaf networks. Use this category to compare compatible modules for switch, server, storage, access and backbone links that need a matched speed, reach and connector type. Confirm the QSFP-DD cage and firmware policy before ordering.
How to specify 400G QSFP-DD / OSFP Transceivers

Match the host: confirm switch, router, OLT, NIC or storage adapter model, port speed, firmware policy and coding requirement.
Check optical parameters: verify speed, form factor, reach, wavelength, fiber type, connector, DOM/DDM support and host coding before choosing a final part number or replacement module.
Plan the link: confirm fiber type, patch cord connector, link distance, attenuation margin, operating temperature and monitoring needs.
Request traceability: ask for compatibility notes, serial labels, DOM/DDM screenshots, optical test records and packing groups for project deployment.

Compare this category with the optical transceivers hub, AOC cables, DAC cables, fiber optic products and fiber optic network solutions. For coding, sampling or BOM support, contact PHILISUN.
