XGS-PON OLT is a high-performance fiber optic access device supporting 10Gbps symmetrical uplink and downlink bandwidth. Compared to traditional GPON (2.5G downlink / 1.25G uplink), it offers 4-8 times the bandwidth capability. With the widespread adoption of 4K/8K video, VR/AR, and cloud services, XGS-PON has become the mainstream standard for fiber optic access networks. Furthermore, as the network core, the XGS-PON OLT offers flexible options for operators and enterprises of different sizes through single-port and dual-port configurations.
Key Features of XGS-PON OLT
High Splitting Ratio and High Density
Single-port typically supports a splitting ratio of 1:128 or even 1:256.
Single-port device: Can connect up to 128/256 ONTs/ONUs.
Dual-port device: Can cover up to 512 user terminals in total, greatly saving equipment room space.
Backward Compatibility (Combo PON Mode)
Most modern XGS-PON OLTs support Combo PON technology, allowing GPON and XGS-PON to operate simultaneously on the same fiber, enabling a smooth evolution from legacy networks to 10G networks.
Low Latency and High Security
Utilizes advanced DBA (Dynamic Bandwidth Allocation) algorithms to reduce latency to millisecond levels. Also supports AES-128 encryption to ensure data transmission security.
Single port vs. Dual port XGS-PON OLT: How to choose?
Feature | 1*Port XGS-PON OLT | 2*Port XGS-PON OLT |
Applicable Scale | Micro-communities, stand-alone office buildings | Medium-sized office buildings, smart parks |
Reliability | Basic Level | Support dual-link redundancy configuration potential |
Scalability | Limited, suitable for fixed locations | It has strong capabilities and can be managed by region according to needs |
Typical Application Scenarios
1. Smart Enterprises and POL Campus Networks
In the construction of all-optical campus networks, dual-port OLTs can separately handle production and office networks, achieving service isolation. Their 10G symmetrical bandwidth perfectly supports video conferencing and large CAD file transfers.
2. 5G Base Station Backhaul (Small Cells)
XGS-PON features a precise time synchronization protocol. Single-port OLTs are often deployed in edge cabinets as high-speed backhaul links for 5G small cells.
3. High-End FTTH Residential Areas
For operators offering gigabit packages, single/dual-port OLTs can quickly provide 10G access capabilities in high-end residential areas with minimal initial installation costs.
4. Smart Cities and Video Surveillance
In the security field, multiple 4K surveillance cameras require significant uplink bandwidth. XGS-PON OLTs are the best choice for urban backbone network access.
Why Choose XGS-PON OLTs?
If you are looking for a high-performance, low-cost, and easy-to-maintain next-generation fiber access solution, the XGS-PON OLT is the perfect choice. Whether for FTTH, FTTB, or POL, the 10G symmetrical speed ensures your network will remain competitive for the next 5-10 years.
