SFP transceiver modul Hikvision HK-SFP-1.25G-20-1310-DF 1250 Mbit/s

The Hikvision HK-SFP-1.25G-20-1310-DF is a fiber optic SFP transceiver module designed for use in high-speed networking equipment. It provides a data transfer rate of 1250 Mbit/s and operates from a 3.3 V supply, supporting reliable short- to medium-range optical links. The module is RoHS certified, which indicates compliance with environmental and safety directives and ensures compatibility with a wide range of switches, routers and media converters that accept SFP form-factor modules.

Advantages

This SFP transceiver delivers stable single-fiber or dual-fiber optical connectivity suitable for gigabit-class links. Its compact SFP form factor allows hot-pluggable installation into compatible network ports without powering down equipment. The module’s 1310 nm wavelength and designed range characteristics provide a balance between reach and optical budget for common LAN, data center and telecom access scenarios. RoHS compliance reduces the risk of hazardous substances in electronic assemblies.

Suitable for

• Upgrading switches and routers to fiber connections in enterprise and campus networks
• Connecting media converters and SFP-capable network devices
• Establishing point-to-point fiber links for data centers and wiring closets
• Replacing or stocking spare SFP transceivers for maintenance and network expansion

Key specifications

• Data rate: 1250 Mbit/s
• Optical wavelength: 1310 nm
• Supply voltage: 3.3 V
• Form factor: SFP (hot-pluggable)
• RoHS compliance: yes

How to use

Insert the transceiver into a compatible SFP slot on a switch, router or media converter until it clicks into place. Connect the appropriate single-mode optical fiber cable with matching connectors to the transceiver ports, observing the transmit and receive orientation if using separate fibers. After installation the host device should detect the module and negotiate the link at the supported data rate automatically. Follow the network equipment manufacturer’s instructions to verify link status and configure interface parameters if required.

Recommendations

Handle the optical interfaces with care to avoid contamination; always use dust caps when the transceiver is not connected. Verify that fiber type and connectors match the transceiver specifications and that link budgets meet distance requirements before deployment.
