1000BASE-T RJ45 SFP Module

Overview A compact, hot-pluggable 1000BASE-T RJ45 SFP copper transceiver engineered for seamless integration with SFP/SFP+ ports. Delivers reliable Gigabit Ethernet over copper cabling up to 100 meters using Cat5e or higher, enabling flexible media conversion between fiber and copper networks without downtime. Ideal for data centers, enterprise LAN aggregation, access switches, and network edge devices.

Key Features

Standard: IEEE 802.3ab (1000BASE-T) compliant
Interface: SFP form factor uplink; RJ45 8P8C copper port
Data Rate: 1000 Mbps (Gigabit Ethernet)
Reach: Up to 100 meters over Cat5e/Cat6/Cat6a/Cat7
Media: 4-pair UTP/STP copper cable, auto MDIX
Duplex: Full duplex with auto-negotiation
Hot-pluggable: Insert or remove with no system power-down
Plug-and-play: No driver or configuration required for standard host devices
Diagnostic: Digital Diagnostic Monitoring (DDM) support (where supported by host)
Operating Temperature: Commercial: 0°C to 70°C; Extended/Industrial options available on request
Compliance: RoHS compliant; CE and FCC standards where applicable
Power Consumption: Low-power design (typical < 1W)
LEDs: Link/activity and speed indication via host chassis or integrated LED (platform dependent)
MTBF: High reliability design with long mean time between failures

Functional Benefits

Simplifies network design by converting SFP slots to copper Gigabit ports without adapters
Enables flexible uplink options and switch interconnection in mixed fiber/copper deployments
Supports link auto-negotiation and auto MDIX to eliminate crossover cable concerns
Reduces spare part inventory by using a single SFP module type for many platforms
Low power profile minimizes thermal impact in dense switch environments

Compatibility and Installation

Compatible with standard SFP ports on switches, routers, and servers that support 1000BASE-T SFP modules
Operates with most mainstream network operating systems and hardware; vendor-specific compatibility lists available on request
Installation: Insert module into SFP port until latched; connect RJ45 cable; module is recognized and negotiates link automatically
Use Cat5e or higher cabling to guarantee full Gigabit performance and reach. For distances <100 m, quality of cable and connectors influences performance.

Ordering guidance

Confirm host device support for 1000BASE-T SFP modules and any vendor compatibility lists before purchase.
Choose cable category (Cat5e minimum) based on installation distance and futureproofing requirements (Cat6/Cat6a recommended for higher margin).
For deployments in harsh environments, specify industrial/extended-temperature version.
