Gigalight launched the second-generation multi-mode parallel optical engine

Recently, Gigalight successfully completed real-time monitoring 4-12 road Tx optical power of the second-generation multi-mode parallel optical engine, and equipped with the newly developed Gigalight successful 40G QSFP+ SR4 GEN2 optical transceiver module. The second generation optical engine core objective research is to develop a micro-optical structure LENS, multi-channel parallel VCSEL optical power monitoring, and easy to bind at high speed module circuit board.

Gigalight generation 40G QSFP+ SR4 GEN2 optical modules with integrated optical devices coupled with a unique lens to achieve real-time monitoring of optical power TX transmit function that transmit TX optical power of effective monitoring, play a stabilizing role emitted optical power. Common market QSFP+ SR4 TX optical modules actually do not have real-time monitoring of the emitted light power, not only by the laser array chip VCSEL ARRAY vertical cavity surface emitting limiting characteristic, add the feedback optical device under existing QSFP+ package is also very difficult. Gigalight 40G QSFP+ SR4 GEN2 success of research and development, more stable the Gigalight leadership in optical engine technology.
