Introduction to 10/100/1000BASE-T SFP Module

The SFP transceiver modules are hot-pluggable I/O devices that plug into module sockets. The transceiver connects the electrical circuitry of the module with the optical or copper network. There are many choices of SFP modules. You may see an SFP module labeled as 10/100/1000BASE-T SFP. As we know, 1000BASE-T is a standard for Gigabit Ethernet over copper wiring. How about 10/100/1000BASE-T SFP module? What is a 10/100/1000BASE-T SFP module? In this post, a brief introduction about 10/100/1000BASE-T SFP module will be given.


The 10/100/1000BASE-T SFP small form-factor pluggable (SFP) transceiver is based on the SFP Multi Source Agreement (MSA). It is a copper SFP supporting 10/100/1000BASE-T copper Ethernet standards. It is compatible with the Gigabit Ethernet and 1000BASE-T standards as specified in IEEE 802.3z and 802.3ab. 10/100/1000BASE-T electrical SFP transceivers use an integrated RJ-45 connector with transformer and PHY IC. The link length is up to 100m over four pair Category 5 UTP cabling. With the hot pluggability, the module offers a flexible and easy way to be installed into SFP MSA compliant ports at any time without the interruption of the host equipments operating online. Besides, this 10/100/1000Mbps SFP transceiver operates at wide temperature ranges and provides high performance. It is ideal for full-duplex Gigabit Ethernet connectivity to high-end workstations and wiring closets utilizing existing copper network infrastructure. And it provides a convenient way to add a copper connection to an SFP type switch that would typically be used for fiber SFPs. Picture below shows a Juniper EX-SFP-1GE-T SFP copper transceiver. It is a 10/100/1000BASE-T copper SFP, which is compliant with the Gigabit Ethernet standard as specified in IEEE STD 802.3 and can fully satisfy the 10/100/1000BASE-T application.

10/100/1000BASE-T SFP modules are extremely versatile, working with many equipment that support the SFP type of interface: Ethernet switches, routers and any other networking equipment. They support 10/100/1000 Mbps data-rate in excess of 100 meters and are ideally suited for implementing small form-factor Network Interface Cards (NICs) and uplinks. As such, it is highly appropriate for use in such high-density applications as LAN 10/100/1000BASE-T Fiber Channel, Gigabit Ethernet LAN switch applications, Gigabit Ethernet media converters, switch-to-switch interfaces, switch to switch SerDes interface, switch to switch SGMII interface, switched backplanes, gaming devices, router/server interfaces and other optical transmission systems.
