Shenzhen, China, August 17, 2015 −  Gigalight successfully developed second generation multi-mode parallel optical engine that is capable of real-time monitoring on 4-12 channels of TX optical power, and equipped it on the Gigalight second generation 40G QSFP-SR4 optical transceiver. The core objective of second generation optical engine is to develop a micro-optics structured LENS, realize power-monitoring of multichannel parallel VCSEL light path, and bond easily to high speed module circuit boards.

Gigalight 40G QSFP+ SR4 GEN2 optical module applies integrated optical device which carried our innovative coupling Lens Array, to realize real-time monitoring of TX optical power, the function can effectively monitor and stabilize the TX optical power. The common QSFP+ SR4 optical module on the market actually do not have theTX optical powerreal-time monitoring function, for that is not only restricted by launch mode of VCSEL ARRAY,but also very difficult to embed a feedback optical signal on the current QSFP+ form factor. Gigalight successful development of 40G QSFP+ SR4 GEN2 strengthens its leadership in optical engine technology.

The picture below shows the relevant parameter of Gigalight second generation 40G QSFP-SR4equipped with second generation optical engine.The eye mask margins for all the 4-lanesare are higher than 30%, Rx sensitivity is better than -13DBM, TX power monitoring for 4 channels is normal.
