Módulo transceptor SFP BlueOptics 490NAC0100-BO cobre 1250 Mbit/s

The BlueOptics 490NAC0100-BO Copper SFP transceiver module is a compact networking component designed for 1.25 Gigabit Ethernet links over copper. With a maximum data transfer rate of 1250 Mbit/s and a single RJ‑45 Ethernet port, this silver-coloured SFP module supports short-range connections up to 100 m and is suited for integration into switches, media converters and other SFP-compatible network equipment. The module is lightweight (approximately 20 g) and offers a calculated MTBF of 1,000,000 hours for long-term deployment planning.

Advantages

The module provides a standardized SFP form factor that enables hot‑swappable installation and easy replacement without system downtime. Its 1.25 Gigabit Ethernet interface delivers backward-compatible operation with existing Fast Ethernet and Gigabit Ethernet infrastructure where applicable. The copper RJ‑45 port simplifies connection to copper cabling, avoiding the need for fiber media in short-distance links. The product's compact size and low weight facilitate use in dense rack environments and space-constrained network devices.

Suitable for

• Short-range Ethernet connections in wiring closets and server rooms
• Upgrading SFP-capable switches or media converters to copper links
• Temporary or permanent links between network devices within 100 m
• Environments requiring hot-swappable transceivers for maintenance

How to use

Before installation, verify that the target device supports SFP copper transceivers and that the firmware or hardware compatibility list includes copper SFP modules. Power down the device if recommended by the manufacturer, insert the BlueOptics 490NAC0100-BO module into an available SFP slot until it seats firmly, and connect a standard Ethernet cable to the RJ‑45 port. After insertion, power the device on if required and confirm link status via the device LEDs or management interface. For hot‑swappable systems, follow the device vendor's guidance for safe insertion and removal to prevent transient network issues.

Recommendations

Use Category 5e or better twisted-pair copper cabling for reliable links up to the specified 100 m. Keep SFP slots and module connectors free of dust when not in use and avoid excessive mechanical stress on the connector during insertion and removal. Consult the host device documentation for supported link speed negotiation and duplex settings to ensure proper operation at 1.25 Gigabit speeds where supported.
