SFP Copper Module StarTech MA-SFP-1GB-TX 1000BASE-T SFP to RJ45 Cat6/Cat5e 10/100/1000 Mbps 100m

The StarTech.com MA-SFP-1GB-TX compatible SFP module provides 1 Gigabit Ethernet connectivity over copper with an RJ45 interface for use with Cisco Meraki switches and routers. Designed to fit SFP ports, this copper transceiver supports 10/100/1000 Mbps operation over Cat5e/Cat6 cabling and delivers a maximum reach of up to 100 m (328 ft). The module is hot-swappable and comes in a compact aluminium housing.

Advantages

This SFP-to-RJ45 transceiver enables reliable 1000BASE-T links without changing existing copper cabling and supports legacy 10BASE-T and 100BASE-TX speeds. Its hot-swappable design allows upgrades or replacements with minimal network downtime. The unit is compact and low-power, with typical consumption under 1.3 W, and is backed by StarTech.com’s lifetime warranty and multilingual technical support.

Suitable for

• Adding Gigabit Ethernet ports to switches or routers with SFP slots
• Connecting SFP-equipped Cisco Meraki MS225, MS250, MX400 and similar devices to copper networks
• Short-run copper links within wiring closets, offices, or equipment racks (up to 100 m)

Когда может не подходить

This copper SFP module is not suitable for links longer than 100 m or for fiber-based infrastructure; fibre SFPs are required for longer distances or when optical connections are needed. It does not provide Digital Diagnostic Monitoring (DDM), so remote optical/port diagnostics are not available through the module.

Key specifications

• Data rate: 10/100/1000 Mbps (1000BASE-T capable)
• Media type: Copper (RJ45)
• Connector: RJ45
• Maximum cable distance: 100 m (328 ft)
• Typical power consumption: < 1.3 W
• MTBF: 4,655,371 hours
• Housing: Aluminium, colour: silver
• Form factor: SFP

How to use

Insert the module into an available SFP slot on a compatible switch or router until it latches, then connect a Cat5e/Cat6 RJ45 cable between the module and the network device. The transceiver is hot-swappable, so it can be installed or replaced while the host device is powered on; allow the device to recognise the module and establish link. Ensure connected network equipment is configured for the desired speed and duplex settings if manual configuration is required.

What to consider before purchase

• Ensure your switch or router supports third-party MA-SFP-1GB-TX compatible modules
• Confirm required link distance does not exceed 100 m over copper
• Verify you need an RJ45/copper SFP rather than a fiber SFP
• Check that lack of DDM (Digital Diagnostic Monitoring) is acceptable for your monitoring needs

Usage recommendations

Use Cat5e or Cat6 cabling for best Gigabit performance, keep cable runs under 100 m, and install or replace the module while the host equipment remains powered to minimise downtime. For fibre runs or distances beyond 100 m choose a compatible fiber SFP module.
