## Summary description

Opton SFP-RJ45/1G is an SFP module with an integrated RJ-45 socket for 1 Gigabit Ethernet connectivity. Designed to convert SFP slots to copper Ethernet ports, it enables linking network devices such as switches, routers and servers over standard CAT cabling. Useful for flexible port expansion, network upgrades and mixed-media deployments.

## Long description

Opton SFP-RJ45/1G is an SFP module with an integrated RJ-45 socket that provides 1 Gigabit Ethernet connectivity. It converts an SFP port into a copper Ethernet port, allowing network equipment with SFP slots—such as switches, routers and servers—to connect over standard CAT5e/CAT6 cabling. The module supports automatic negotiation for 10/100/1000 Mbps and is intended for short-distance copper links inside data centers, wiring closets and office networks.
Advantages
The module enables flexible port expansion without replacing existing switches, offering a compact, hot-pluggable solution for adding copper ports to devices with SFP cages. It reduces the need for separate uplink adapters or replacement hardware by converting fiber-capable slots to standard RJ-45 copper connectivity. Its compliant form factor and low power consumption make it suitable for mixed-media networks and incremental infrastructure upgrades.
Suitable for
 Adding 1G copper ports to SFP-equipped switches and routers
 Connecting servers or appliances to copper-based LANs using SFP slots
 Temporary or permanent media conversion in wiring closets and rack cabinets
 Network upgrades where fiber ports need to support copper endpoints
Key specifications
 Data rate: 1 Gigabit Ethernet (auto-negotiation up to 1000 Mbps)
 Interface: RJ-45 copper socket integrated into SFP form factor
 Media type: Standard twisted-pair Ethernet (Cat5e/Cat6 recommended)
 Connector: 8P8C (RJ-45)
 Hot-pluggable: Yes
 Power consumption: Low (typical SFP class power profile)
 Operating environment: Indoor use, typical network equipment temperature ranges
How to use
Insert the module into a compatible SFP slot on your switch, router or server until it clicks into place. Connect a standard Ethernet cable to the RJ-45 socket; the link should establish automatically with auto-negotiation handling speed and duplex. Monitor link LEDs on the host device for status and verify network settings on connected equipment if needed. To remove, disengage any retention mechanisms and pull the module straight out while the device is powered down if recommended by the host vendor.
Usage recommendations
Use quality CAT5e or CAT6 cables for reliable 1 Gbps links and keep copper runs within recommended distance limits for Gigabit Ethernet. Verify SFP slot compatibility with the host device and consult device documentation if the host requires specific module vendor support. For mixed-media deployments, check link speed and duplex settings after insertion and consider using surge protection in environments prone to electrical interference.
