The 2.5G SFP Copper RJ45 100m 2.5GBASE-T Transceiver Module is a compact copper-based transceiver designed to extend multi-gigabit Ethernet connectivity through existing network infrastructure. It supports data rates up to 2.5Gbps and provides transmission distances of up to 100m over standard CAT5e or better Ethernet cabling. Featuring an RJ45 electrical interface and a hot-pluggable SFP form factor, the module can be installed directly into compatible switches, routers, servers, and other networking equipment.

Designed for practical network upgrades, this copper SFP module allows organizations to increase link speeds beyond 1Gbps without immediately replacing their existing copper cabling infrastructure. It is suitable for switch-to-switch links, server and network device connections, LAN upgrades, and other multi-gigabit Ethernet applications where a compact and cost-effective copper connectivity solution is required.

As a B2B manufacturer, FiberMania supports OEM and customized solutions for 2.5G SFP Copper RJ45 transceiver modules. Customers can work with our engineering team to specify requirements such as host equipment compatibility, EEPROM coding, firmware or management parameters, operating temperature range, labeling, housing identification, packaging, and other project-specific requirements.

We can also provide customized product configurations for different networking environments and deployment volumes, with engineering support available for sample evaluation, compatibility testing, and production preparation. OEM branding, private labeling, and customized packaging can be provided according to project requirements.

Q1. Can this module be used to upgrade a 1G network to 2.5G?

Yes. When installed in a compatible multi-gigabit Ethernet port, the module can help upgrade network links from 1Gbps to 2.5Gbps while allowing the existing copper cabling infrastructure to remain in place. The actual operating speed depends on the capabilities of both connected devices and the network equipment.

Q2. What cable should be used with this 2.5G copper SFP?

CAT5e or better twisted-pair Ethernet cable is generally suitable for 2.5GBASE-T connections up to 100m. For existing installations, cable quality, termination, and overall link conditions should be considered when determining the achievable performance.

Q3. Is this copper SFP suitable for switches from different vendors?

The module uses a standard SFP form factor, but compatibility is not determined by the mechanical interface alone. Some switches and network devices require vendor-specific EEPROM coding or have restrictions on supported transceiver types. Customized coding can be discussed for specific equipment platforms.

Q4. What is the difference between a 2.5G copper SFP and a conventional RJ45 network port?

A conventional RJ45 port is integrated directly into the network device, while this module provides an RJ45 copper interface through an SFP slot. This allows network equipment with compatible SFP ports to use copper Ethernet connectivity without requiring a built-in RJ45 port.

Q5. Can the module be supplied with OEM branding?

Yes. OEM branding and private-label production are available for qualified B2B projects. Product labels, packaging, EEPROM coding, and other configurable items can be discussed based on equipment compatibility and order requirements.
