## Summary description

The BlueOptics ET4202-RJ45-BO is a fiber optic SFP transceiver designed for high-speed data transfer over distances up to 100 meters. It features an aluminum housing for durability and weighs only 20 grams. This module is ideal for network applications requiring reliable and efficient connectivity.

## Long description

The BlueOptics ET4202-RJ45-BO 100 m is a compact SFP transceiver designed for 1000BASE-T Ethernet links over twisted-pair copper cabling. Housed in aluminum and weighing approximately 20 grams, this SFP module delivers data transmission at up to 1.25 Gbps over distances up to 100 meters when used with compatible network equipment. The module uses an RJ45 electrical interface and conforms to MSA form-factor expectations, making it suitable for hot-pluggable insertion into supported switch, router or network appliance SFP ports.
Advantages
The transceiver provides Gigabit Ethernet performance over standard copper cabling while maintaining a small SFP footprint and an aluminum housing for mechanical durability. It is engineered to match common 1000BASE-T electrical signaling and to function with hardware platforms that support the same SFP form factor and protocol. Lightweight construction and a standardized RJ45 interface simplify installation and replacement in rack-mounted and compact network devices.
Suitable for
Gigabit Ethernet uplinks and access ports in managed and unmanaged switches
Server or storage connectivity in data centres and server rooms
Copper-based links between rack-mounted network devices up to 100 m
Field replacement or spare module use in compatible network appliances
Key specifications
Interface type: SFP with RJ45 electrical connector
Supported data rate: up to 1.25 Gbps (1000BASE-T)
Maximum reach over Cat5e/Cat6 copper cable: up to 100 meters
Housing material: aluminum
Weight: approximately 0.02 kg
Form factor: hot-pluggable SFP module
How to use
Insert the SFP transceiver into a compatible SFP port on your switch, router or network appliance with the module's ejector latch aligned. Connect a standard RJ45 twisted-pair patch cable between the transceiver and the remote RJ45 port or patch panel. The link negotiates at Gigabit speeds where both ends and the cabling support 1000BASE-T. For safe installation, power down the port if required by the equipment manufacturer, or follow hot-swap procedures specified in the host device documentation.
Usage recommendations
Use high-quality Cat5e or Cat6 cabling and reliable RJ45 patch cords to achieve the specified 100 m reach and consistent 1.25 Gbps performance. Verify host device compatibility with 1000BASE-T SFP modules and update device firmware if recommended by the manufacturer to ensure proper negotiation and stability.
