Network transceiver module BlueOptics JL486A SFP28 fiber optic 25 Gbps 1310 nm

BlueOptics JL486A is an SFP28 fiber optic transceiver module designed to deliver up to 25 Gbps of optical connectivity over single-mode fiber using a 1310 nm wavelength. The module fits into standard SFP28 ports on switches, routers and uplink ports and is supplied as a single unit. It supports point-to-point 25G links and is intended for data centre or enterprise environments requiring a compact 25G optical interface with LC connector compatibility and long-reach capability.

Advantages

The transceiver provides a compact SFP28 form factor enabling high-density ports on network equipment while supporting a 25,000 Mbit/s line rate. Using a 1310 nm optical wavelength and LC duplex connector, the module is suitable for longer single-mode runs and reduces the need for more expensive transceiver types. Its compatibility with standard SFP28 interfaces makes it straightforward to install in compatible switches and routers without additional cabling changes.

Suitable for

• 25 Gbps uplinks between switches in data centres
• Connection from servers or NICs with SFP28 ports to aggregation switches
• Optical links in enterprise campus networks requiring single-mode reach
• Replacement or spare transceiver for 25GBASE-LR SFP28 ports

When it may not be suitable

This module is designed for single-mode fiber and a 1310 nm wavelength; it is not suitable for multimode fiber links or for applications that require different wavelengths (for example 850 nm) or different reach classes. It also requires an SFP28-compatible port on the host device and will not function in devices that only support older SFP speeds or proprietary, non-SFP28 interfaces.

Key specifications

• Form factor: SFP28
• Data rate: up to 25,000 Mbit/s (25 Gbps)
• Wavelength: 1310 nm
• Connector: LC duplex
• Target link length: up to 10,000 m on single-mode fiber (typical for long-reach 25G optics)
• Supply: single unit per pack

How to use

Insert the BlueOptics JL486A transceiver into an empty SFP28 slot on a powered-off or hot-swappable compatible switch or router according to the device manufacturer’s guidance. Connect LC duplex single-mode fiber patch cables, ensuring correct polarity between transmit and receive fibers. After insertion, verify the link status in the host device management interface and confirm the port negotiates at 25 Gbps. Monitor optical power and diagnostic data where available to ensure reliable operation.

What to consider before purchase

• Ensure the host port supports SFP28 and 25 Gbps operation
• Verify the network uses single-mode fiber and LC connectors
• Check required link distance to confirm 10 km class reach is sufficient
• Confirm device compatibility or vendor interoperability policies if strict vendor-lock checks are present

Usage recommendations

For stable 25 Gbps links, use high-quality single-mode LC patch cables, maintain correct fiber polarity, and validate link parameters after installation. Keep spare modules for critical uplinks and document serial/asset information in your inventory for quicker replacement.
