## Long description

Opton SFP-RJ45/10M-1G is a compact SFP media converter module that provides an RJ-45 copper interface supporting 10 Mbps to 1 Gbps data rates. Designed to plug into standard SFP ports, the module enables connection of twisted-pair Ethernet cables where only SFP slots are available. It is suitable for network uplinks, device interconnection and flexible deployment in switches, routers and optical equipment that require a copper Ethernet port without altering the host device.
Advantages
The module occupies a single SFP slot and offers autosensing of 10/100/1000 Mbps link speeds and full/half duplex where applicable, which simplifies integration into mixed-speed networks. Its compact form factor and hot-pluggable design allow quick installation or replacement without powering down the host. The SFP-RJ45/10M-1G reduces the need for additional cabling adapters and enables copper connectivity on devices that lack built-in RJ-45 ports.
Suitable for
 Adding copper Ethernet ports to switches or routers with free SFP slots
 Creating short-distance uplinks between network switches and servers
 Connecting end devices in data centers, server rooms or office networks
 Temporary or permanent network links where fiber ports must interface with copper cabling
Key specifications
 Interface: SFP host connector to 8P8C (RJ-45) copper port
 Supported data rates: 10 Mbps, 100 Mbps, 1 Gbps
 Media type: Cat5e/Cat6 twisted-pair copper cabling
 Auto-negotiation: supported for speed and duplex
 Form factor: hot-pluggable SFP module
 Operating temperature range: typical commercial range suitable for indoor networking equipment
How to use
Insert the Opton SFP-RJ45/10M-1G into a compatible SFP slot on the host device until it clicks into place. Connect an RJ-45 Ethernet cable to the module's copper port and to the remote device. The module will negotiate link speed and duplex automatically based on the connected device and cable category. Monitor link/activity LEDs on the host device to confirm successful connection. To remove, gently pull the module from the SFP slot while following the host equipment’s hot-swap or removal procedures.
Usage recommendations
Use high-quality Cat5e or Cat6 cables for best performance at gigabit speeds and keep cable runs within standard maximum lengths (100 m for copper Ethernet). Verify SFP slot compatibility with third-party modules in the host device and, if necessary, check vendor documentation for any required firmware or configuration. Install or remove the module in a static-safe environment and avoid excessive force when seating the module.
