Transceivers

Optical Transceivers — SFP, SFP+, QSFP28, QSFP56, QSFP-DD & OSFP for 1G to 800G Networks

Optical transceivers are the interface between your network switch or server and the fiber or copper cable connecting your infrastructure. At Resilient Tec, every transceiver is EEPROM-coded to match the OEM firmware signature of your switch — meaning your Cisco, Mellanox, Arista, or Juniper device sees it as a native module, with no errors, no suppression of third-party warnings, and no CLI overrides needed.

We stock transceivers from 1G SFP through 800G OSFP — short-range, long-range, CWDM, DWDM, BiDi, and breakout variants — compatible with all major enterprise, data center, and telecom platforms.

Why Choose Compatible Transceivers Over OEM?

Cost: Compatible transceivers typically cost 60–90% less than OEM modules with identical performance
Same optical specs: Built to MSA and IEEE standards — same wavelength, same reach, same power draw
No CLI overrides needed: Our EEPROM coding means your switch recognizes the module natively
Lifetime warranty: We stand behind every module — if it fails, we replace it
In stock, ships fast: We maintain deep inventory of the most requested SKUs
