## Summary description

The BlueOptics B304-BO is a Copper SFP transceiver module designed for high-speed data transfer at 1000 Mbit/s. It features a standard SFP interface, making it compatible with various networking equipment. This module is ideal for connecting network devices over short distances, providing reliable performance and ease of installation.

## Long description

The BlueOptics B304-BO is a Copper SFP transceiver module built for Gigabit Ethernet links. Designed to fit standard SFP slots, this module delivers a maximum data transfer rate of 1000 Mbit/s over copper cabling and provides one RJ-45 Ethernet port. With support for typical copper distances, it enables short-range connections of up to 100 m and is suitable for integration into switches, routers and media converters that accept SFP-form factor modules.
Advantages
The module offers a compact SFP form factor for flexible installation and easy hot-swap replacement. It supports 1 Gbit/s operation over existing copper infrastructure, allowing fast data throughput without the need for fiber optics for short runs. Compatibility with standard SFP interfaces ensures broad device interoperability while the built-in RJ-45 connector simplifies cabling and reduces the need for additional adapters.
Suitable for
 Connecting switches and routers within the same wiring closet or server room
 Short-range uplinks and downlinks where fiber is unnecessary
 Retrofitting Gigabit Ethernet ports into equipment with SFP slots
 Media conversion scenarios from SFP slot to copper Ethernet
Key specifications
 Data transfer rate: 1000 Mbit/s (Gigabit Ethernet)
 Ports: 1 × RJ-45 copper Ethernet port
 Maximum cable distance: up to 100 m over Cat5e/ Cat6 copper cabling
 Interface: standard SFP form factor compatible with Gigabit SFP slots
How to use
Insert the BlueOptics B304-BO into an available SFP slot on your networking device while the device is powered according to the manufacturer's instructions or hot-swap if supported. Connect a suitable Cat5e or Cat6 copper Ethernet cable to the RJ-45 port and to the corresponding network device. Configure link speed and duplex settings on connected equipment if manual configuration is required; otherwise, rely on auto-negotiation. Verify link status through the host device’s management interface or LEDs.
Usage recommendations
Use high-quality Cat5e or Cat6 cabling for reliable performance and ensure cable runs do not exceed 100 m for optimal signal integrity. Confirm SFP compatibility with the host device and consult device documentation for any vendor-specific firmware requirements or supported transceiver lists.
