Hikvision SFP Tranceiver Module HK-SFP-1.25G-20-1550

Hikvision SFP Tranceiver Module HK-SFP-1.25G-20-1550 The Hikvision HK-SFP-1.25G-20-1550 is a 1.25Gbps single-mode BiDi SFP optical transceiver module designed for long-distance fiber network connections. Using a single 9/125µm single-mode fiber and LC connector, it transmits at 1550nm and receives at 1310nm over distances of up to 20km. Its compact, hot-pluggable SFP design makes it suitable for compatible network switches and other SFP-equipped devices where long-range Gigabit-class fiber connectivity is required. Key Features 1.25Gbps SFP optical transceiver module. Supports 1.25G Ethernet connectivity. Single-mode, single-fiber BiDi operation. 9/125µm single-mode fiber support. Single LC optical connector. Up to 20km transmission distance. Tx 1550nm / Rx 1310nm wavelengths. -9 to -1dBm transmit optical power. Maximum receive sensitivity of -21dBm. Hot-pluggable SFP design. SFP MSA compatible. 3.3V DC operating voltage. 0°C to 70°C operating temperature range. RoHS compliant. Designed to operate as a complementary pair with the HK-SFP-1.25G-20-1310. 1.25Gbps Fiber Connectivity The HK-SFP-1.25G-20-1550 supports a data rate of 1250Mbps, providing 1.25Gbps optical connectivity for compatible network equipment. The SFP form factor allows the module to be installed in supported SFP ports without occupying the space required by larger optical interfaces. Up to 20km Transmission Distance Designed for long-distance network links, the module supports transmission distances from 0 to 20km over compatible 9/125µm single-mode fiber. This makes it suitable for network links between buildings, surveillance infrastructure and other applications where copper Ethernet cannot provide the required distance. Single-Fiber BiDi Technology The HK-SFP-1.25G-20-1550 uses bidirectional optical transmission to carry transmit and receive signals over a single fiber strand. It transmits at 1550nm and receives at 1310nm, reducing the fiber requirement compared with conventional dual-fiber optical links. Complementary 1310nm Module Pairing Hikvision specifies that the HK-SFP-1.25G-20-1550 must operate together with the complementary HK-SFP-1.25G-20-1310 module. The 1550 model transmits at 1550nm and receives at 1310nm, while the matching 1310 model transmits at 1310nm and receives at 1550nm, allowing bidirectional communication over the same single-mode fiber. Hot-Pluggable SFP Design The module uses the Small Form-factor Pluggable (SFP) architecture and supports hot-pluggable operation. It is SFP MSA compatible, providing a compact optical connectivity solution for compatible network switches and transmission equipment. Designed for Network Transmission The combination of 1.25Gbps performance, single-mode fiber support and a 20km optical range makes the HK-SFP-1.25G-20-1550 suitable for compatible network transmission infrastructure, including switch-to-switch links and professional IP surveillance networks.
