Shenzhen, China, Jun 28, 2018 – Gigalight announced to launch a new generation 40G QSFP+ LR4 10km optical transceiver with lower cost. Based on Gigalight’s 100G optical engine technology, the cost of the new product has been greatly optimized. Prior to that, Gigalight has been producing the 40G QSFP+ LR4 optical modules through external sourcing of TOSA and ROSA. However, due to the market competitiveness and the customer's demand for cost performance, Gigalight applies the mature 100G optical engine technology to the development of 40G optical modules, and finally realizes the target of customer concern.

Gigalight's new generation 40G QSFP+ LR4 10km optical transceiver

The transmitter of the new generation 40G QSFP+ LR4 optical module adopts Gigalight’s self-made Mini TO and AWG chip, and the receiver adopts the COB packaging technology, which greatly optimizes the cost. For this product, we have restarted the automatic production line of 100G optical modules. 2000 square meters of constant temperature, constant wet, dust-free workshop, equipped with 3 fully automatic, high precision wire bond / die bond production equipment, as well as automatic testing equipment, these conditions make the product have good consistency. The new generation 40G QSFP+ LR4 optical module has been able to achieve small batch production, producing 2000 to 3000 per month to meet current supply needs.

TOSA and ROSA of the new generation 40G QSFP+ LR4 10km optical transceiver

The new generation of 40G QSFP+ LR4 optical module supports both 40GE and OTU3 dual-rate applications and fully supports no error optical transmission over a single mode fiber link of up to 10km distance. In the operating temperature range, the power consumption is less than 2.5W, and the margin of the optical eye diagram is superior to 20%. The OMA sensitivity at the receiver is superior to -11.5dbm in BER 1E-12, and the jitter RMS is less than 2.5ps. The fabrication process of this optical module is very mature, the performance is very stable, and the quality is absolutely reliable. With the characteristics of low cost and high efficiency, it can be widely used in the optical interconnection between the switches of the data centers.
