Source Photonics Receives ECOC Industry Award for its Family of 50G PAM4 SFP56 Transceivers for 5G Fronthaul Wireless Deployment


50Gbps SFP56 optical modules empowers next-gen cost-effective fronthaul connectivity



WEST HILLS, Calif.–(BUSINESS WIRE)–Source Photonics, a leading vendor of innovative and reliable optical connectivity products for Access and Datacom applications, today announced that it has received the 2022 Industry Award in the category of Innovative FTTx products from the European Conference on Optical Communications (ECOC) – a premier industry exhibition held in Basel, Switzerland during September 19-21, 2022.

ECOC created the fiber communication industry awards in six categories to put the spotlight on technology and product commercialization happening within the industry. The awards recognize and highlight key industry achievements in advancing optical components, photonic integration, optical transport, networking, data center innovation and innovative FTTx products.

To meet the most pressing bandwidth requirements of global 5G customers, Source Photonics officially released the 50G PAM4 SFP56 product for upgrading 5G fronthaul networks from March 2022. The initial products are 50G LR and FR PAM4 transceivers using analog CDRs, which supports 10km and 2km transmission distances. The 50G SFP56 achieves 50% port savings by upgrading the rate of one 25Gb/s eCPRI transceiver to 50Gb/s, creating flexibility for further improvement of wireless forward bandwidth. This is the industry first in product commercialization to apply PAM4 signaling into analog CDR. The product meets the range of industrial temperature applications with power consumption of as low as 1.5W.

As global operators accelerate the deployment of 5G networks, promote the differentiated application of 5G multi-services, and release more spectrum resources, 5G networks put forward higher bandwidth requirements for fronthaul. Source Photonics has subsequently extended the SFP56 product portfolio to cover 50GBASE-LR, 50GBASE-ER, 50GBASE-BR10, 50G CWDM6, 50GBASE-BR40 and other optical interfaces. The application scenarios range from 10 to 40km, from dual fiber to single fiber with bi-directional transmission and from multiple rate support for backward compatibility with prior generations of 25G SFP28 and 10G SFP+ optical transceivers.

The product series use the 25G DFB laser developed in house by Source Photonics to provide customers with low power consumption, short latency, and cost-effective transceiver solutions for 5G fronthaul networks. Source Photonics has conducted in-depth cooperation with the world’s leading 5G equipment manufacturers, and the qualification has been progressing smoothly. The initial deployment of SFP56 expects to ramp up the volume in 2023.

Source Photonics is a vertically integrated design powerhouse for optical chips and optics assembly, which enables industry leading optical performance and power consumption. The product portfolio of SFP56 transceivers for 5G fronthaul includes:

50G PAM4 DML design, supports 10km transmission, compliant with IEEE P802.3cd standards

Single fiber with bi-direction transmission, supports 10km transmission, compliant with IEEE P802.3cp standards

Supports 6 CWDM wavelengths with extended temperature, compliant with ITUT-G.695 CWDM definition, supports 10km transmission

50G PAM4 EML design, supports 10km transmission, compliant with IEEE P802.3cd standards

Single fiber with bi-direction transmission, supports 30 and 40km transmission, compliant with IEEE P802.3cp standards
