GPON OLT Interface Card HUAWEI GPFD — 16x GPON C+ ports, for 5608/5680/5683 OLT

HUAWEI GPFD is a GPON OLT interface card that provides sixteen GPON C+ ports and is designed for use in Huawei 5608, 5680 and 5683 OLT chassis. The module enables high-density fiber subscriber access, aggregation of services and centralized management of ONUs in access network sites. It supports deployment in central offices and distribution nodes where multiple GPON splits and subscriber profiles are required.

Advantages

The card delivers sixteen GPON C+ ports in a compact line-card form factor, enabling efficient port consolidation and reduced rack space usage. It is implemented for interoperability with compatible Huawei OLT platforms and supports standard GPON functions for subscriber access, service provisioning and OLT-side management. The design focuses on stable signal transmission, manageable port density and simplified integration into existing fiber access infrastructures.

Suitable for

• Fiber-to-the-home (FTTH) subscriber aggregation in central office OLT racks
• High-density GPON deployment at distribution sites or medium-sized POPs
• Network upgrades where additional GPON ports are required without chassis replacement
• Service providers needing centralized ONU management and GPON service provisioning

Key specifications

• Number of GPON ports: 16 GPON C+ ports
• Form factor: OLT interface/line card for compatible chassis
• Compatibility: Designed for integration with the specified Huawei OLT chassis models
• Functionality: GPON subscriber access, service aggregation and ONU management
• Deployment environment: Indoor telecom equipment racks and distribution enclosures

How to use

Install the GPON OLT interface card into an empty compatible slot in the Huawei OLT chassis following the chassis installation procedures and safety guidelines. After mechanical insertion and connector engagement, perform the required chassis-level configuration to enable the ports, provision GPON service profiles and register ONUs. Use the OLT management interface to configure VLANs, bandwidth profiles and OAM settings per subscriber group.

Recommendations

Ensure the chassis firmware and management software are up to date before inserting the module; verify optical power budgets, splitter design and ONU compatibility when planning GPON links to achieve reliable signal levels and expected subscriber throughput.
