400GBASE-FR4 QSFP-DD PAM4 1310nm 2km LC connector DOM Optical Transceiver

Cost-effective 400 Gigabit Modules Quad Small Form-Factor Pluggable Double Density (QSFP-DD) transceiver for 400Gigabit Ethernet applications.

Product overview

UPONCOMM Technology 400GBASE Quad Small Form-Factor Pluggable Double Density (QSFP-DD) portfolio offers customers a wide variety of super high-density transceiver modules and the flexibility of 400 Gigabit Ethernet connectivity options for data center, high-performance computing networks, enterprise core and distribution layers, and service provider applications. The QSFP-DD modules are the new generation of 400G transceiver modules based on a QSFP-DD form factor.


The 400GBASE-FR4 module supports link lengths of up to 2km SMF with duplex LC connector. It is compliant to IEEE 802.3bs, 400GBASE-FR4 Spec of 100G Lambda MSA group, and 400GAUI-8/CEI-56G-VSR-PAM4 standards. The 400 Gigabit Ethernet signal is carried over four CWDM grid optical wavelengths. Multiplexing and demultiplexing of the four wavelengths are managed within the device.
