Source Photonics Unveil the Tri-mode 50G PON OLT SFP-DD Optical Transceivers with Live Demonstration during OFC’25
West Hills and San Francisco, California, April 1, 2025 – Source Photonics Inc., a leading global provider of innovative and reliable technology solutions for communications and data connectivity for use in hyperscale and AI datacenters, today announces the release of its small form factor, low-power solution for the next generation high-speed PON networks – the 50G PON OLT SFP-DD. This SFP-DD product leverages industry-leading optoelectronic chip technology with live demonstration to support downstream optical bandwidth of up to 50G NRZ signals and upstream optical/electrical interface line rates of up to 25G burst reception, support XGS-PON/50G dual-mode and GPON/XG(S)-PON/50G-PON tri-mode co-existence. The optical power budget is designed to cover or be compatible with existing ODN networks. This solution will help operators maximize the value of fiber optics, achieving next-generation bandwidth upgrades while balancing network evolution and cost, further advancing the development of broadband optical access.
With the initiation of F5G-A and China’s “Double 10G Strategies,” large-scale deployment of 50G PON is on the verge of taking off. The 50G PON OLT optical module features the smallest SFP-DD packaging to increase the number of ports per line card for customers, allowing network upgrades without changing the layout of equipment rooms or the number of devices. Leveraging its deep R&D capabilities in EML laser chip technology, Source Photonics has successfully developed an integrated SOA high-power 50G 1342nm EML chip, which is first applied to the 50G PON OLT SFP-DD C+ optical module product; the product supports industrial-grade temperatures to meet the demands of network deployment in harsh telecommunication environments.
During live demonstration, the Rx burst mode sensitivity was tested below <-28.5dBm under loud-soft environment with stronger Tx reference at -13dBm or higher. These are very competitive results to support existing ODN use cases with good performance margin. Currently, Source Photonics has initiated technical dialogues and sample testing of this product with leading global PON network equipment manufacturers.
