50G-PON Technology
Next-generation experiences for the entire community
50G-PON is the next standards-based evolution in passive optical networking technology. With 5 times the capacity of XGS-PON along with associated technologies like PON slicing, 50G-PON brings game-changing experiences to business, academic, and residential subscribers.

50G-PON expands opportunities with mobile x-haul, academic institutions and large campuses, advanced telepresence for rural healthcare, bandwidth hungry venues, and residential AR/VR and 8K streaming.
ITU-standards based means less risk and more flexibility with simultaneous support of symmetric 50G and 50/25 (downstream, upstream) services.
50G-PON expands your network's capabilities with simultaneous Tri-PON support of 50G-PON, XGS-PON, and GPON on the same fiber — making it easy to introduce new services while preserving existing infrastructure and subscriber connections.
One network. Every service. Simple, scalable 50G-PON on Calix One.
Separate networks are inefficient, leading to siloed ops teams, slow business turn-ups, duplicated workflows, and higher OPEX. Watch this quick overview video to learn more about converging all services on PON using the same fiber infrastructure, same hardware, and same operating system with Calix One.

Technology detail
The next evolution in PON technologies
- 50G-PON is an International Telecommunication Union (ITU-T G.9804) standard for delivering next-generation capabilities for FTTx deployments.
- Defined as ITU-T G.9804 HSP, 50G-PON establishes the framework for the next evolution in passive optical networking.
- 50G-PON supports both asymmetric (50G downstream / 25G upstream) and symmetric (50G downstream / 50G upstream) configurations on the same fiber, giving CSPs the flexibility to target residential and business market segments simultaneously.
- 50G-PON operates at 1286nm +/- 2nm upstream and 1342nm +/- 2nm downstream, allowing it to coexist on the same fiber as existing GPON and XGS-PON deployments without disrupting current services.
- This wavelength separation gives CSPs exceptional flexibility and a lower total cost of ownership by reusing existing fiber infrastructure rather than deploying new ones.
- Support for higher-speed business and wholesale leased line services eliminates the need for dedicated separate networks and fibers, simplifying infrastructure and reducing overall deployment complexity.
- A single converged network provides common management, increased automation, and reduced operational costs — while allowing CSPs to leverage existing investments in resources, infrastructure, and people.
- Allows a physical broadband network including the PON to be partitioned into multiple logical networks, called a network slice, delivering services on par with dedicated active Ethernet networks while still using a single wavelength for all subscribers.
- Slices may be statically reserved or dynamically created, allocated, and removed — and each slice can have distinct bandwidth, QoS, and latency parameter settings.
- Slices can be established to provide business subscribers with a minimum bandwidth guarantee, while offering a significantly higher non-guaranteed bandwidth class.
- Service in one slice can be guaranteed for throughput, latency, and jitter without impacting other logical slices.
- Slice isolation enables per-slice performance, traffic separation, security, privacy, and end-to-end management and orchestration.
