Fiber optic transceiver module BlueOptics JD119A 1250 Mbit/s SFP 1310 nm

The BlueOptics JD119A fiber optic transceiver module is an SFP form-factor device designed for single-channel optical data links. It supports a maximum data transfer rate of 1250 Mbit/s and transmits at a wavelength of 1310 nm, suitable for short- to medium-range multimode or single-mode fiber connections depending on system design. The module provides a compact, hot-pluggable interface that integrates into network equipment with SFP ports to enable optical connectivity where copper links are unsuitable or unavailable.

Advantages

The module’s SFP form factor offers compactness and hot-swap capability, simplifying installation and replacement without powering down equipment. Operating at 1310 nm and supporting up to 1250 Mbit/s ensures compatibility with a range of legacy and current networking applications. Its straightforward optical interface reduces signal loss and supports stable data transmission over fiber cabling in Ethernet and other serial optical link environments.

Suitable for

• Upgrading network ports from copper to fiber for improved signal integrity
• Connecting switches, routers and media converters with SFP slots
• Short- to medium-distance fiber links in enterprise or industrial networks
• Environments requiring hot-pluggable modular transceivers for maintenance or scaling

Key specifications

• Form factor: SFP (Small Form-factor Pluggable)
• Data rate: up to 1250 Mbit/s
• Optical wavelength: 1310 nm
• Interface: fiber optic transmit/receive pair
• Mounting: hot-pluggable for modular network equipment

How to use

Insert the BlueOptics JD119A module into an available SFP slot on a compatible switch, router or media converter until it latches. Connect the appropriate fiber optic cable to the module’s optical port, ensuring correct connector type and polarity. After installation, check link status indicators on the host device and confirm data transmission at the expected rate. Follow device vendor guidance for any required configuration of interface parameters or link aggregation settings.

Usage recommendations

Use factory-quality fiber patch cables and observe correct connector cleaning procedures before mating to avoid signal loss. Match the module’s wavelength and fiber type to the network design, and verify that host equipment supports SFP optical modules. For reliable operation, avoid excessive bending of fiber and keep the module’s housing free of dust and debris.
