HUAWEI OLT SFP-module CSHF C+ — 16x XGS-PON/GPON Combo Optical Line Terminal-kaart

The HUAWEI OLT SFP Module CSHF C+ — 16x XGS-PON/GPON Combo Optical Line Terminal Card is a high-density PON access card engineered for fiber access networks. This module integrates 16 combo ports that support both XGS-PON and GPON standards, allowing network operators to deploy mixed-generation PON services on a single line card. The card is intended for aggregation in OLT chassis to deliver high-capacity upstream and downstream transmission for residential broadband, business connectivity, and FTTH projects.

Advantages

The card provides flexible service delivery by supporting coexistence of XGS-PON and GPON on the same 16-port card, reducing the need for separate hardware for different PON generations. Its high port density enables space-efficient deployment in central office or edge OLT chassis, simplifying network expansion. The module is designed for stable throughput and deterministic performance suitable for multi-service access, while facilitating smooth migration from GPON to XGS-PON without major equipment changes.

Suitable for

• High-density FTTH deployments in residential neighborhoods
• Mixed residential and business broadband services in metro networks
• Progressive migration scenarios from GPON to XGS-PON
• Multi-service access platforms requiring both GPON and XGS-PON interfaces

Key specifications

• Port count: 16 combo PON ports supporting both XGS-PON and GPON operation
• Supported standards: XGS-PON (10 Gbps symmetrical) and GPON (up to 2.5 Gbps downstream)
• Form factor: line card designed for installation in compatible OLT chassis
• Transmission capability: high-capacity upstream and downstream PON aggregation
• Deployment scope: central office and edge OLT environments for FTTH and business access

How to use

Install the module into a compatible OLT chassis following the manufacturer's mechanical and ESD procedures. Configure the OLT management system to assign PON profiles and service parameters for each port, selecting XGS-PON or GPON mode according to subscriber and service requirements. Connect downstream splitters and optical distribution network fibers to the module's ports and verify optical power levels and signal quality through the OLT's monitoring tools. Apply firmware and configuration backups as part of standard commissioning.

Recommendations

For stable operation, plan port allocation to separate legacy GPON subscribers from XGS-PON subscribers where possible, monitor optical power and upstream bandwidth usage, and ensure the OLT chassis firmware and management software support mixed PON operation. Use appropriate optical splitters and fiber plant testing to confirm link margins for both GPON and XGS-PON services.
