SFP+ Fiber Module Grandstream GWNSFP4 10Gbps, Single-Mode, 10 km

The Grandstream GWNSFP4 is an SFP+ fiber transceiver designed to deliver 10 Gbps connectivity over single‑mode fiber for distances up to 10 km. The module fits SFP+ slots in compatible switches, routers and media converters and supports hot‑pluggable installation for fast replacement or network upgrades. It is intended to provide a reliable high‑speed uplink or long‑distance link in enterprise networks, data centers and service provider environments.

Advantages

The GWNSFP4 offers 10 Gbps throughput on a compact SFP+ form factor, combining high bandwidth with space efficiency. Single‑mode optical design enables links up to 10 km, which helps extend network segments without additional fiber hardware. Hot‑pluggable capability simplifies installation and maintenance, and the standardized SFP+ interface ensures broad compatibility with devices that support 10 G fiber transceivers.

Suitable for

• High‑speed uplinks between switches and routers
• Long‑distance links in enterprise and campus networks
• Data center server to switch connections
• ISP backbone and aggregation links
• Media converters and optical extension equipment

Key specifications

• Data rate: 10 Gbps
• Fiber type: single‑mode
• Maximum reach: up to 10 km
• Form factor: SFP+ (hot‑pluggable)
• Wavelength: typical single‑mode transmission wavelength
• Interface: duplex LC optical connector

How to use

Insert the GWNSFP4 module into an empty SFP+ slot on a compatible networking device while the device is powered on or off, observing the device manufacturer’s guidance for hot‑plug operation. Connect single‑mode fiber cables with LC duplex connectors to the module ports, ensuring correct polarity and secure connections. Verify link status through the host device’s port indicators or management interface, and configure link speed and duplex settings according to network design if required.

Usage recommendations

Use single‑mode fiber with appropriate transceivers on both ends of the link and verify compatibility with the host device vendor’s SFP+ support list. Avoid bending fiber cables below recommended radius, keep connectors clean, and follow ESD precautions when handling the module to maintain optical performance and reliability.
