Hikvision HK-SFP-1.25G-20-1550 SFP Module
Hikvision HK-SFP-1.25G-20-1550 SFP module delivers reliable single-mode fiber connectivity for Gigabit Ethernet networks. This 1.25 Gbps SFP transceiver operates at 1550 nm wavelength with a 20 km transmission distance. It uses a single LC duplex connector and supports digital diagnostics monitoring (DDM). Additionally, it provides stable performance in surveillance backbones, switch uplinks, and long-distance links. Therefore, it suits professional IP camera deployments requiring extended fiber runs. Moreover, its hot-pluggable design allows easy installation without network downtime.
Use Cases and Compatibility
Hikvision HK-SFP-1.25G-20-1550 SFP module excels in medium to long-range fiber connections. For example, large surveillance systems use it to link remote camera clusters to central NVRs across campuses, industrial sites, or city perimeters. Similarly, retail chains deploy it for inter-store connections between buildings or parking lots separated by hundreds of meters.
Furthermore, educational institutions apply it to connect multiple buildings on campus while maintaining high-speed data transfer for video streams. In addition, transportation hubs such as airports, ports, and railway stations rely on it for backbone links between control rooms and distant camera locations. Meanwhile, smart city projects benefit from its 20 km reach for connecting traffic cameras, public safety devices, and monitoring stations over fiber infrastructure. Consequently, it addresses the need for reliable, high-bandwidth fiber connectivity in large-scale IP surveillance networks.
The module complies with the SFP Multi-Source Agreement (MSA) and IEEE 802.3z standards. It operates on single-mode fiber (9/125 µm) and uses a 1550 nm DFB laser transmitter with a PIN photodiode receiver. It supports data rates up to 1.25 Gbps and achieves a typical transmission distance of 20 km. Moreover, it features Digital Diagnostic Monitoring Interface (DDMI) for real-time monitoring of optical power, temperature, voltage, and laser bias current. As a result, network administrators can quickly identify and resolve issues. The LC duplex connector ensures secure, low-loss fiber connections.
This transceiver works seamlessly with Hikvision switches, NVRs, media converters, and third-party devices supporting 1000BASE-LX/LH standards. It pairs effectively with compatible 1310 nm SFP modules for bidirectional links when required. For optimal viewing of remote feeds, pair with high-quality displays from our monitors category.
