Description

The Hikvision HK-SFP-1.25G-20-1550 is a compact, hot-pluggable SFP (Small Form-factor Pluggable) transceiver module built for single-mode fiber installation, enabling stable high-speed data transmission over long distances. With its LC single-fiber bi-directional connector and compliance with SFP-MSA standards, it supports 1.25 Gbps Ethernet — ideal for IP camera networks, NVR links, or building-wide data backbones. The module transmits at a wavelength of 1550 nm and receives at 1310 nm, allowing a communication range of up to 20 km, which makes it suitable for linking remote buildings or long-distance surveillance setups. Operating on 3.3 V power and rated for 0 – 70 °C working temperature, it’s designed to be reliable across typical environmental conditions. Because it is hot-swappable, it can be installed or replaced without powering down the system — offering flexibility and convenience for network maintenance or upgrades. In short, this SFP module is a cost-effective, high-performance solution for extending and stabilizing fiber-based security and data networks.
