ProLabs has launched a long range 80km DWDM solution by pairing its 100G erbium-doped fibre amplified multiplexer (EDFAMUX) (pictured) with QSFP28 PAM4 DWDM 2x50G transceivers.

The EDFAMUX is an integrated solution that combines the multiplexer, EDFA, and dispersion compensator in a single 1 rack unit (1RU) 19″ container to diminish space requirements and resolve complexity while enhancing flexibility. The 100G EDFAMUX models were designed to work with QSFP28 100G DWDM PAM4 optics, which require amplification to go any distance and dispersion compensation beyond 5km.

The 100G EDFAMUX solution with a transceiver portfolio supports 10G & 100G EDFAMUX deployments. The 10G EDFAMUX models are a simple and affordable solution for long-distance applications from 80km to 200km that can be used with standard 10G 80km/ZR fixed colour or tuneable DWDM optics.


“Network operators are looking to reduce engineering and operational complexity as well as shrinking footprint and power consumption through streamlining PAM4 DWDM deployments. By incorporating the EDFA and dispersion compensator inside the multiplexer, coupled with our web-based and command line configuration options, the ProLabs EDFAMUX accomplishes these objectives,” according to Jon Eikel, chief technology officer at ProLabs. “The EDFAMUX simplifies the entire DWDM architecture and deployment while freeing up valuable rack space and power facilities to help service providers continue meeting the market’s explosive bandwidth demand.”
