The FIBERSTAMP FQJ-400P4M50C is a transceiver module designed for up to 500m optical communication applications in liquid immersion environment, and it is compliant to QSFP112 MSA type 1 form factor, IEEE 802.3cu protocol. It uses SiPh chips that integrate a number of active and passive optoelectronic components, 3D packaging technology and industry-leading DSP chips.

The optical module is especially designed for liquid immersion, the case is sealed with the sealing material coating to protect optical engine leaking in the coolant, comparing other liquid immersion solutions in optics, the module case has a pressure test point for liquid leakage ,so case sealing and testing technology has unique testability advantage in manufacture.

This product has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference. It offers very high functionality and feature integration, accessible via a two-wire serial interface.
