Overview

VSOL V1600GS-032 GPON OLT for Compact Fibre Deployments
The V-SOL V1600GS-O32 is a compact, 1U rack-mountable Optical Line Terminal designed for Gigabit Passive Optical Network deployments. It provides a single GPON port to connect multiple Optical Network Units, making it a practical and cost-efficient option for smaller FTTH rollouts. Its standard 19-inch rack form factor simplifies installation into existing infrastructure. This OLT is well suited to ISPs and network operators delivering fibre services across residential estates, small business environments, or rural coverage areas. With support for standard GPON protocols, it ensures stable delivery of high-speed internet, voice, and video services.

Description

The VSOL V1600GS-032 delivers an integrated GPON solution with a built-in 1:32 optical splitter, reducing the need for additional external components and simplifying deployment. Designed for efficient fibre distribution, it combines reliable upstream and downstream performance with flexible uplink options, including Gigabit Ethernet and SFP or SFP+ connectivity. Its compact chassis, straightforward management interfaces, and long transmission reach make it a practical choice for operators aiming to extend fibre access while maintaining operational efficiency. This model, identified by part number VSOL-V1600-G1-O32, is engineered for consistent performance in both urban and remote network environments.

Features

Deployment Advantages and Use Cases
This GPON OLT is optimized for scenarios where space, cost, and simplicity are critical. By integrating a 1:32 splitter directly into the unit, it minimizes external hardware requirements and reduces installation complexity.

Typical applications include:

• Fibre-to-the-home rollouts in residential complexes and estates
• Connectivity for small to medium business parks
• Rural broadband expansion projects
• Entry-level ISP infrastructure builds

Its 20 km transmission capability supports extended coverage without compromising signal integrity, making it suitable for geographically dispersed users.

Connectivity and Port Configuration
The system offers a balanced mix of uplink and access interfaces, allowing flexible integration into core and aggregation networks.

Key interface details include:

• 1 GPON port supporting 1:32 splitting
• 2 Gigabit RJ45 uplink ports
• 1 SFP or SFP+ uplink slot for fibre connectivity
• SC/UPC optical connector type

This combination allows operators to scale bandwidth while maintaining compatibility with existing network topologies.

Performance and Optical Characteristics
The V1600GS-032 is engineered to deliver consistent GPON throughput and reliable optical performance across connected endpoints.

Core performance parameters:

• Upstream rate of 1.244 Gbps and downstream rate of 2.488 Gbps
• Transmission distance up to 20 km
• Wavelength operation at 1490 nm downstream and 1310 nm upstream
• Optical power output of approximately 7.5 dBm with receiver sensitivity down to -32 dBm
• Minimum optical power of at least -10 dBm per port after 1:32 splitting

These specifications ensure stable multi-user connectivity across demanding network conditions.

System Capacity and Throughput
Designed for efficient packet handling and data flow, the unit supports:

• Backplane bandwidth of 29 Gbps
• Forwarding rate of 21.576 Mpps

This enables smooth handling of concurrent traffic streams, including broadband, VoIP, and IPTV services.

Management and Control Interfaces
The device supports multiple management options, enabling flexible configuration and monitoring depending on operational preferences.

Available management modes:

• Console access via USB-COM port
• Web-based interface
• Telnet access
• Command-line interface

These tools provide network administrators with granular control over provisioning, monitoring, and troubleshooting.

Power and Protection
The unit is designed for stable operation across standard power environments while incorporating protection against electrical disturbances.

Power and protection details:

• AC input range of 100 to 240V with support for 110V and 220V systems
• DC adapter rated at 12V and 2A
• Power supply lightning protection up to 4 kV
• Interface protection level rated at 1 kV

Form Factor and Physical Design
The compact 1U rack-mount chassis allows efficient use of space in data cabinets and network racks, supporting clean and organized deployments.

This makes the VSOL-V1600-G1-O32 particularly suitable for environments where rack space is limited but performance requirements remain high.
