A part-number cross-reference is a model-selection starting point, not a blanket device guarantee. Final fit depends on the exact device, firmware or OS, target port and requested coding profile.

Product FAQ

Frequently Asked Questions

Answers to common compatibility, installation and troubleshooting questions.

What is the difference between equipment compatibility and optical compatibility?

Equipment compatibility determines whether the host device recognizes and operates with the module. Optical compatibility determines whether the two ends of the fiber link can communicate correctly. A successful deployment requires both.

Why does a compatible transceiver work in one switch but not another?

Different switch models, hardware revisions, operating systems, and firmware versions may use different transceiver validation rules. A module compatible with one platform may require different coding for another.

Why does the switch report a vendor or part number different from the physical transceiver label?

Compatible transceivers may contain programmed identification information required by the host platform. The vendor or part number reported by the switch can therefore differ from the manufacturer's physical product label.

Why does the link work at one end but show an error at the other end?

Each transceiver must be compatible with its own host device. In a mixed-vendor link, one end may be correctly coded while the transceiver at the opposite end is not fully compatible with its switch or router.

Why does the compatible transceiver work in some ports but not others on the same switch?

Ports on the same device may support different speeds, breakout modes, interface types, or configuration settings. Check the affected port's supported transceiver types, configured speed, lane mode, and other platform-specific requirements.
