Glasvezel-transceiver BlueOptics J4860D 1250 Mbit/s SFP 1550 nm

The BlueOptics J4860D 1250 Mbit/s SFP 1550 nm is a compact fiber optic transceiver module designed for single-channel fiber links. It supports a maximum data transfer rate of 1250 Mbit/s and transmits at a wavelength of 1550 nm. With a lightweight form factor of approximately 20 g and a standard SFP interface, this transceiver is intended for installation in compatible SFP ports on switches, routers and optical equipment to enable reliable optical connections over appropriate fiber types and distances.

Advantages

This SFP transceiver provides a standardized SFP interface for hot-pluggable installation and interoperability with equipment that accepts SFP modules. The 1550 nm wavelength is suitable for long-reach single-mode fiber applications, and the 1250 Mbit/s transfer rate meets common Gigabit and asynchronous communication requirements. The module’s low weight and compact size simplify handling and mounting in dense networking racks.

Suitable for

• Single-mode fiber links requiring 1550 nm transmission
• Switches and routers with SFP ports
• Point-to-point optical connections and WAN links
• Equipment upgrades or replacements where a 1250 Mbit/s SFP module is needed

Key specifications

• Interface type: SFP (hot-pluggable)
• Maximum data transfer rate: 1250 Mbit/s
• Transmission wavelength: 1550 nm
• Typical weight: 0.02 kg
• Form factor: SFP transceiver module

How to use

Install the transceiver into a compatible SFP port on network equipment while the device is powered down or, if supported, use hot-plugging following the equipment manufacturer’s guidance. Connect the appropriate single-mode optical fiber with the matching connector type to the transceiver’s port and ensure proper fiber polarity. Verify link status through the host device’s interface and configure network settings as required for the intended data rate and link operation.

Recommendations

Use the BlueOptics J4860D in environments with compatible single-mode fiber and SFP-supporting hardware. Avoid excessive bending or tension on the fiber cable and follow electrostatic discharge (ESD) precautions when handling the module. Confirm the transceiver’s wavelength and data rate match the remote endpoint to ensure link compatibility.
