SFP Module Opton GTS-SFP-RJ45/10M-1G with RJ-45 Port, 10 Mbps–1 Gbps

Opton GTS-SFP-RJ45/10M-1G is a compact SFP network transceiver that provides copper Ethernet connectivity via an SFP slot. The module integrates a standard RJ-45 port and supports autonegotiation of link speeds from 10 Mbps to 1 Gbps, enabling use in SFP-compatible switches, routers and media converters where copper uplinks or short-distance Ethernet ports are required instead of fiber.

Advantages

The module offers a space-saving form factor for devices with limited port density while preserving flexibility to connect to existing copper cabling. It supports automatic speed negotiation and standard Ethernet signaling for straightforward interoperability with network equipment. Low power consumption and a hot-pluggable design simplify installation and replacement without powering down the host device.

Suitable for

• Converting SFP slots to RJ-45 copper uplinks in switches and routers
• Short-distance connections within wiring closets or between adjacent racks
• Adding Gigabit or 10/100 Mbps access ports to modular network equipment
• Temporary or emergency copper connectivity where fiber ports are occupied

Key specifications

• Interface: RJ-45 copper port via SFP form factor
• Supported link speeds: 10 Mbps, 100 Mbps, 1 Gbps with autonegotiation
• Connector: 8P8C (standard RJ-45)
• Media: Unshielded or shielded twisted-pair copper cabling (Cat5e/Cat6 recommended for Gigabit)
• Form factor: Small Form-factor Pluggable (SFP), hot-pluggable
• Power consumption: low-power design suitable for modular network chassis

How to use

Insert the SFP module into an available SFP slot on a compatible switch or router until it latches. Connect an RJ-45 Ethernet cable to the module’s port and to the corresponding network device or patch panel. The module and the host device will perform autonegotiation to establish the appropriate link speed. For removal, disengage the latch and pull the module straight out while the host supports hot-swap operation.

Usage recommendations

Use Category 5e or better twisted-pair cabling for reliable Gigabit throughput, and keep copper runs within standard length limits (100 m) to maintain signal integrity. Verify that the host equipment supports copper SFP modules in its SFP slots and check link speed settings if manual configuration is required by the switch or router.
