Fiber optic transceiver module Hikvision HK-SFP-1.25G-1310-DF-MM

The Hikvision HK-SFP-1.25G-1310-DF-MM fiber optic transceiver module supports data transmission at 1250 Mbit/s over multimode fiber using a 1310 nm wavelength. Designed for compatibility with networking equipment that accepts SFP modules, it provides a compact 57.2 mm form factor and operates from a 3.3 V supply. The module is RoHS compliant and intended for reliable short- to medium-range multimode fiber links in structured networks, telecommunications closets, and industrial communication systems.

Advantages

This transceiver offers stable 1.25 Gbit/s performance with multimode fiber at 1310 nm while maintaining low power operation at 3.3 V. Its compact SFP-compatible housing simplifies installation into standard SFP slots and minimizes space requirements in switches and media converters. RoHS compliance reduces hazardous substances in manufacturing, and the module's standardized optical parameters ensure interoperability across compatible network devices.

Suitable for

• Fiber uplinks between switches and routers within local networks
• Fiber connections in data center top-of-rack and access layers
• Industrial Ethernet links where multimode fiber is used
• Media converters and patch-panel fiber interfaces

Key specifications

• Data rate: 1250 Mbit/s (1.25 Gbit/s)
• Operating wavelength: 1310 nm
• Fiber type: multimode fiber (MM)
• Supply voltage: 3.3 V
• Form factor: SFP module, compact 57.2 mm width
• Standards compliance: RoHS

How to use

Install the transceiver into an available SFP slot of a compatible switch, router, or media converter, ensuring the module is fully seated and any retention latch is secured. Connect multimode fiber optic patch cords that match the module's duplex optical interface and verify correct connector types at both ends. Power up the host device and check link/activity indicators to confirm optical link establishment. Follow equipment vendor guidelines for hot-swap procedures and handling to avoid electrostatic discharge or contamination of optical interfaces.

Recommendations

Maintain clean fiber connectors and use dust caps when the transceiver is not connected. Use multimode fiber rated for the intended link distance and inspect patch cords for damage. Avoid bending fiber beyond its minimum bend radius and follow manufacturer guidance for operating temperature ranges. For reliable interoperability, verify firmware and SFP compatibility lists of the host equipment.
