Yes. We code transceivers to match the host platform requirements of major switch and router vendors including Cisco, Juniper, Arista, HPE, Huawei, Nokia, and others. Tell us your platform model and required OS version, and we will ship modules that are recognized natively by your equipment.

Datasheets, compatibility matrices, and S-parameter reports are available for all standard products. Contact our sales team or visit the product pages on our website to request documentation.

Provide us with your switch make, model, and OS version. We code the transceiver firmware accordingly before shipment. If you are testing for the first time, we recommend ordering a sample unit to validate compatibility in your specific environment before placing a volume order.

Switch vendors occasionally introduce transceiver whitelisting in new OS releases. We track major platform updates and can provide recoded firmware matching the new OS requirements. Contact technical support if your existing APEX modules stop being recognized after a switch upgrade.

Contact our sales team by email, WhatsApp, or WeChat with your part number and quantity. We will confirm pricing, lead time, and shipping options. For first-time customers, we typically recommend starting with a sample order to validate compatibility before scaling to production volumes.

We ship via DHL, FedEx, and UPS for express delivery, typically 3-7 business days to most destinations. For volume orders, we also offer air freight and sea freight options. We can ship on your courier account or ours, and we handle all export documentation.
