HK-SFP-1.25G Series SFP Module, Support 1.25G Ethernet

The HK-SFP-1.25G-20-1550 optical module is an essential component for modern networking, enabling the transition from copper-based limitations to the vast reach of fiber optics. Engineered by Hikvision to meet rigorous industrial standards, this Small Form-factor Pluggable (SFP) transceiver allows for high-speed data exchange with minimal signal loss. It is specifically designed for use in Hikvision switches and other compatible networking hardware, providing a reliable backbone for large-scale security deployments and campus-wide networks.

Key Features
The standout feature of this module is its 1550nm wavelength transmission, optimized for long-distance single-mode fiber (SMF) applications. With a maximum transmission distance of 20km, it bridges the gap between geographically separated network nodes without the need for frequent repeaters. The module supports hot-swapping, allowing network administrators to install or replace the transceiver without powering down the host device, thus ensuring zero-downtime maintenance and maximum system availability.

Performance / Technology
Connectivity is powered by a standard LC duplex interface, providing a secure and stable optical link. The module operates at a data rate of 1.25Gbps, which is fully compliant with IEEE 802.3z standards for Gigabit Ethernet. For enhanced reliability, the HK-SFP-1.25G-20-1550 is built with low power consumption and high EMI (Electromagnetic Interference) resistance, ensuring that critical video streams and data packets remain uncorrupted even in electrically noisy industrial environments.

Design & Ergonomics
The module features a rugged metallic housing that provides excellent thermal dissipation and structural protection for the delicate internal laser components. Its compact SFP form factor follows industry-standard dimensions, making it compatible with a wide range of switches, routers, and media converters. The pull-tab latching mechanism ensures a secure fit within the SFP slot while allowing for effortless removal when necessary, simplifying cable management in high-density server racks.

Compatibility / Use Cases
This 1.25G optical module is the ideal solution for connecting remote IP cameras to a central NVR, linking switches between different buildings, or extending internet services across a large facility. It is perfectly suited for use in city-wide surveillance projects, educational campuses, and industrial parks in Abu Dhabi and beyond. By utilizing single-mode fiber, it provides a future-proof connection that is immune to the distance limitations and interference associated with traditional UTP copper cabling.

Why This Product Stands Out
The Hikvision HK-SFP-1.25G-20-1550 stands out by offering a perfect balance of long-range performance and professional reliability. While many generic modules struggle with compatibility or thermal stability, this Hikvision-certified transceiver is tested for seamless integration with high-end security hardware. Its ability to maintain a stable 1.25Gbps link over 20km makes it one of the most dependable and essential accessories for any serious fiber-based networking project in 2026.
