Source Photonics unveils first 400G QSFP-DD ER8 supporting up to 40km reach

At the Optical Networking and Communication Conference & Exhibition (OFC 2019) in San Diego, CA, USA (5-7 March), Source Photonics Inc of West Hills, CA, USA (which provides optical connectivity products for data centers, metro and access networks) has unveiled what it says is the first 400G QSFP-DD ER8 supporting up to 40km reach, giving a live 400G traffic demonstration over 40km single-mode fiber leveraging Source Photonics’ compact TOSA/ROSA design.

The 400G ER8 in 40km reach is expected to fill the gap between the currently available low-cost and power-efficient PAM4-based 400G products in a shorter 10km reach. This will also serve as a more practical alternative to the higher-cost, coherent-based optical transceivers suitable for greater than 80km reach applications that are out in the market.

“The 400G ER8 in QSFP-DD form factor will enable wider deployments of 400G solutions for telecom and routing applications,” believes chief engineer Frank Chang PhD.

In addition to the ER8 demo, at OFC 2019 Source Photonics also gave live demonstrations of a wide range of higher-data-rate PAM4-based products, e.g. 400G LR8, 400G DR4, 100G FR and 50G ER.
