- Product Introduction
400G QSFP‑DD FR4 1310nm 2km Optical Transceiver Module
400G QSFP‑DD FR4 Transceiver Module
The 400GBASE‑FR4 QSFP‑DD transceiver is a cost‑effective high‑speed optical solution for short‑reach single‑mode data‑center interconnection. Adopting CWDM4 wavelength‑division multiplexing technology, it transmits full 400G PAM4 bandwidth over one‑pair duplex single‑mode fiber, greatly reducing cabling investment for campus DCI, intra‑building and row‑to‑row cloud & AI network deployment.
