Copper SFP transceiver CBO JW089A-BO, 1000 Mbit/s, up to 100 m

BlueOptics Copper SFP transceiver JW089A-BO provides a 1000 Mbit/s (Gigabit) Ethernet link over standard copper cabling with a maximum reach of up to 100 m. The small form-factor pluggable (SFP) module is intended for insertion into compatible SFP ports on switches, routers and network devices to enable copper-based uplinks and short-distance connections. The module supports hot-plugging and is designed for environments such as server rooms and access-layer switching where a reliable, low-latency copper connection is required.

Advantages

This Copper SFP transceiver delivers a stable Gigabit Ethernet connection over existing copper infrastructure without the need for fiber. Its compact SFP form factor allows flexible deployment in devices with limited space, and compatibility with standard RJ45 copper connections simplifies cabling and equipment integration. The transceiver supports standard link speeds and auto-negotiation for straightforward setup and predictable performance over short runs.

Suitable for

• Uplinks between access switches and aggregation switches within a rack or data closet
• Connecting servers or appliances to switches when fiber is not required
• Temporary or permanent short-distance links in office and server room environments
• Scenarios where existing copper cabling is preferred or cost-effective

Key specifications

• Data rate: 1000 Mbit/s (Gigabit Ethernet)
• Media: copper cabling using RJ45 connection
• Maximum reach: up to 100 m over appropriate copper cable
• Form factor: SFP (small form-factor pluggable), hot-pluggable
• Supported link features: auto-negotiation for speed and duplex

How to use

Insert the module into a compatible SFP slot on the network device until it seats securely, then connect a standard Ethernet cable to the transceiver’s RJ45 port. The device should detect the module automatically; configure link settings on the switch or router as needed, or allow auto-negotiation to establish speed and duplex. Verify link status via the device management interface or LED indicators and test connectivity end-to-end to confirm proper operation.

Recommendations

Use quality, properly rated copper cabling (Cat5e or higher) and maintain cable lengths within the specified maximum to ensure reliable Gigabit links. Avoid exposing the module to excessive dust, moisture or mechanical stress when installing or handling. For mixed environments, ensure device firmware or vendor compatibility lists include the transceiver to prevent interoperability issues.
