Q&A
Commonly asked questions
No. Under the Magnuson-Moss Warranty Act and similar global consumer protection laws, OEMs cannot void your equipment warranty simply because you use a third-party transceiver. Your equipment warranty remains intact.
Yes. Our QSFP28 modules can be coded for major OEM platforms (Cisco, Juniper, Arista, Nvidia, etc.) and support open networking environments including SONiC.
A compatible generic version can be provided and coded before delivery.
Common types include SR4 (MMF, short reach), PSM4 (parallel SMF), CWDM4 (SMF up to ~2km), LR4 (SMF up to ~10km), and extended reach options like ER4. Each is designed for different distances and fiber types.
