SFP28 transceiver module BlueOptics JL484A 25000 Mbit/s 850 nm

The BlueOptics JL484A SFP28 transceiver module is a hot-pluggable fiber optic interface designed for 25 Gbit/s class data transmission. Operating at an 850 nm wavelength, this module supports a maximum data transfer rate of 25000 Mbit/s and is suited for short-reach multimode links in data centers and enterprise networks. The compact SFP28 form factor enables high-density deployment in compatible switches, routers and servers while maintaining signal integrity for high-performance networking applications.

Advantages

The module provides a standardized SFP28 interface for straightforward integration into existing optical ports and supports 25 Gbit/s line rates for demanding traffic loads. Its operation at 850 nm makes it compatible with common multimode fiber cabling and short-distance connections. The transceiver is hot-swappable, reducing downtime during maintenance or upgrades, and its industry-standard mechanical dimensions ensure broad vendor interoperability.

Suitable for

• Short-reach 25 Gbit/s links in data center aggregation and top-of-rack switches
• High-performance server interconnects requiring SFP28 transceivers
• Multimode fiber connections using 850 nm optics for campus or enterprise networks
• Network upgrades where backward-compatible SFP28 ports are available

Key specifications

How to use

Install the BlueOptics JL484A into a compatible SFP28 port on a switch, router or server while the host device is powered on or according to the host manufacturer's hot-swap instructions. Ensure matching multimode fiber cabling and connectors are used and that the link settings on both ends—such as speed and duplex—are configured to support 25 Gbit/s operation. Monitor link status through the host device management interface and follow standard handling procedures to avoid contamination of optical interfaces.

Recommendations

For reliable performance, use OM3 or OM4 multimode fiber for short-reach 25 Gbit/s links, keep fiber connectors clean, and verify that the transceiver is compatible with the host equipment’s SFP28 port. Follow vendor guidelines for temperature and environmental conditions to ensure stable operation.
