ZTE FTTH GPON LineCard 16-port GPON OLT with 16 B+ transmit/receive modules

The ZTE FTTH GPON LineCard 16-port GPON OLT with 16 B+ transmit/receive modules is a modular optical line card for deployment in OLT chassis to provide GPON access for fiber-to-the-home networks. This line card supplies 16 GPON interfaces with B+ class transceivers, enabling aggregation and distribution of downstream and upstream optical signals to connected ONTs. The design targets high-density subscriber environments where compact capacity expansion and consistent optical performance are required.

Advantages

This line card integrates 16 GPON ports in a single module, reducing rack space and simplifying chassis-based capacity scaling. B+ class transmit/receive modules provide standardized optical power and receiver sensitivity suitable for typical FTTH reach and split ratios. The unit is compatible with OLT platforms that accept ZTE line cards, supporting centralized management of subscriber interfaces and facilitating predictable optical link budgeting for service provisioning.

Suitable for

• Service provider OLT capacity expansion in urban and suburban FTTH deployments
• High-density multi-dwelling unit (MDU) and apartment building fiber access
• Central office or aggregation-site installations requiring modular GPON ports
• Network upgrades where standardized B+ optical interfaces are required

Key specifications

• Port count: 16 GPON interfaces
• Transceiver class: B+ transmit/receive modules on each port
• Optical interface: GPON compliant downstream and upstream wavelengths
• Form factor: Modular line card for compatible OLT chassis
• Density: High-density single-module solution for 16 subscriber interfaces

How to use

Install the line card into a compatible ZTE OLT chassis following the chassis manufacturer’s procedures for hot-swap or powered insertion. Connect single-mode fiber pigtails or patch cords to the GPON ports and ensure correct fiber routing and labeling. Configure the OLT control plane to recognize and enable the new GPON ports, then perform optical power tests and provisioning of ONT profiles. Monitor optical levels and alarm conditions through the OLT management system to verify stable operation.

Usage recommendations

Place the line card in an environment that meets the OLT chassis environmental specifications. Verify optical split ratios and distance limits against B+ transceiver parameters when planning subscriber reach. Use proper ESD handling during installation and perform post-installation optical power verification to ensure each GPON port meets expected signal levels.
