Hikvision HK-SFP-1.25G-20-1550 SFP-module 1,25 Gbit/s 20 km Singlemode 1550 nm

The Hikvision HK-SFP-1.25G-20-1550 is a high-performance SFP (Small Form-Factor Pluggable) transceiver module designed for Gigabit Ethernet and Fiber Channel applications. It operates at a data rate of 1.25 Gbps and supports transmission distances up to 20 km over single-mode fiber. The module uses a 1550 nm DFB laser transmitter and a 1310 nm PIN photodiode receiver, enabling BiDi (Bidirectional) communication over a single strand of fiber with an LC Simplex connector. It is hot-pluggable, MSA compliant, and features DDM/DOM support for real-time monitoring of optical parameters. This module is ideal for extending network reach in metropolitan area networks (MANs), enterprise campus networks, and service provider access networks.

Advantages

Reliable long-distance connectivity up to 20 km over single-mode fiber, low power consumption (<1W), and hot-pluggable design for easy installation and maintenance. DDM/DOM support allows proactive network management. MSA compliance ensures interoperability with a wide range of networking equipment.
