Source Photonics receives ECOC Industry Award for 50G PAM4 SFP56 transceivers for 5G front-haul wireless deployment

At the European Conference on Optical Communications (ECOC 2022) in Basel, Switzerland (19-21 September), Source Photonics Inc of West Hills, CA, USA (which provides optical connectivity products for access and datacom applications) has received the 2022 Industry Award in the category of Innovative FTTx products.

ECOC created the fiber communication industry awards in six categories to put the spotlight on technology and product commercialization 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 front-haul networks from March. 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 claimed to be the industry first in product commercialization to apply PAM4 signaling into analog CDR (clock & data recovery). 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 present higher bandwidth requirements for front-haul. 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 10km 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 (distributed feedback) laser developed in house by Source Photonics to provide low power consumption, short latency, and cost-effective transceiver solutions for 5G front-haul networks. Source Photonics says that it has conducted in-depth cooperation with the world’s leading 5G equipment manufacturers, and that qualification has been progressing smoothly. The initial deployment of SFP56 is expected to ramp up volume in 2023.

Source Photonics’ product portfolio of SFP56 transceivers for 5G front-haul includes:

  • SFP56 50GBASE-LR: 50G PAM4 DML design, supports 10km transmission, compliant with IEEE P802.3cd standards;
  • SFP56 50GBASE-BR10: single fiber with bi-direction transmission, supports 10km transmission, compliant with IEEE P802.3cp standards;
  • SFP56 50G CWDM: supports six CWDM wavelengths with extended temperature, compliant with ITUT-G.695 CWDM definition, supports 10km transmission;
  • SFP56 50GBASE-ER: 50G PAM4 EML design, supports 10km transmission, compliant with IEEE P802.3cd standards;
  • SFP56 50GBASE-BR40: single fiber with bi-direction transmission, supports 30km and 40km transmission, compliant with the IEEE P802.3cp standards.
