SFP-Transceiver BlueOptics J4859DCM 1250 Mbit/s Glasfaser 1310 nm

The BlueOptics J4859DCM is an SFP fiber optic transceiver designed for single-channel data links. With a nominal wavelength of 1310 nm and a maximum data transfer rate of 1250 Mbit/s, this module supports standard fiber connections for gigabit and legacy serial optical networks. The transceiver is compact and lightweight (approximately 20 g) and is supplied as a single unit in a silver housing suitable for installation in compatible SFP ports.

Advantages

The module offers stable optical transmission at 1310 nm and a data rate of up to 1250 Mbit/s, making it suitable for many short- to medium-range fiber applications. Its SFP form factor ensures broad compatibility with switches, routers and media converters that accept SFP modules. The small physical size and light weight simplify handling and installation while conserving rack and chassis space.

Suitable for

• Upgrading or repairing SFP ports on switches and routers
• Establishing fiber links for industrial and office networks
• Connecting media converters and optical line equipment
• Temporary optical connections for testing and maintenance

How to use

Insert the BlueOptics J4859DCM into a compatible SFP port following the host device manufacturer’s instructions. Ensure correct orientation and that the port is powered down or handles hot-swap safely if supported. Connect fiber patch cables with suitable connectors to the module’s optical interface and verify link status via the host device. Observe proper ESD handling when installing or removing the transceiver.

Recommendations

For reliable performance, use single-mode fiber compatible with 1310 nm operation and follow the recommended fiber attenuation and connector cleanliness practices. Verify compatibility with the host equipment’s supported SFP profiles and firmware; where possible test the link after installation to confirm correct data throughput and optical levels.
