What is an SFP Transceiver Module?
An SFP Transceiver Module, which stands for Small Form Factor Pluggable, is a compact optical transceiver used to convert electrical signals to optical signals and vice versa. It connects a fiber optic cable to compatible ethernet switches, routers, transceivers and other networking equipment.
SFP Transceivers provide high-speed fiber optic connectivity and allow these networking devices to connect and transmit data over fiber optic links. They offer significant advantages over copper cables including high bandwidth, electromagnetic interference immunity, radio frequency interference resistance and long reach.
What are the main types of SFP Transceivers?
The main types of SFP Transceivers are:
SFP – Standard Small Form Factor Pluggable. Supports ethernet speeds up to 1Gbps. Uses LC connectors and supports SMF fiber up to 40km or MMF up to 2km.
SFP+ – Enhanced Small Form Factor Pluggable. Supports ethernet speeds up to 10Gbps. Often used for 10GBASE-T and 10GBASE-SR ethernet networks using LC connectors and SMF fiber up to 30km or MMF up to 150m.
XFP – 10 Gigabit Small Form Factor Pluggable. Supports 10GBASE-LR, 10GBASE-LRM and 10GBASE-LRWL transceivers for 10Gbps speeds and up to 40km reach. Uses LC or MPO connectors. Often used in 10G data center networks.
CFP – Compact Form Factor Pluggable. Supports ultra-fast ethernet speeds up to 100Gbps. For 100GBASE-SR4, 100GBASE-LR4 and 100GBASE-ER4 transceivers used in 100G ethernet networks. Uses MPO connectors with up to 10km, 40km or 70km fiber reach respectively.
CFP2 – Even smaller than CFP, also supports 100Gbps speeds. Mainly used by data center providers for high-density connections with up to 4.5W transmission power.
Frequently Asked Questions
Can 1G SFP Run at 10G SFP+ Port?
SFP+ slots can take SFP modules, most do but not all. It may depend greatly on the switch models. Besides, the SFP+ port usually doesn’t support speeds under 1G. That is to say, you can’t plug the 100BASE SFP in the SFP+ port. If you are unsure about the connectivity, it is suggested that you consult the vendor to make sure the 10Gb switch port supports dual rate before plugging an SFP transceiver into the SFP+ port on your 10Gb switch.
Will 10Gb SFP+ Run at 1Gb?
This also depends on your switch model. You need to downrate the 10G SFP+ transceiver on the switch, but practically no one will be encouraged to do that.Can the 10G SFP+ transceiver module plugged in one switch be connected to a 1G transceiver plugged in another switch and negotiated? For Ethernet over copper wiring, auto-negotiation is supported. For fiber-based transceivers such as fiber SFP and SFP+ optics, auto-negotiation is not supported.
Why use SFP over Fixed Fiber Types?
SFP modules are interchangeable fiber optic connections that can be used to suit any fiber installation. SFPs will support multiple fiber types and data-rates.
SFPs are hot-swappable and can use replaced, upgraded or repurposed within a network. For example, if a Gigabit Switch is using Fast-Ethernet SFP, the SFP can be replaced with a Gigabit SFP to increase the network speed if needed.
SFP (small form-factor pluggable) Cable Types
SFP transceivers support Multimode fiber (MMF) and Single-Mode fiber (SMF) optical transceivers or UTP copper cabling (copper transceivers).
- Multi-mode fiber optic cables use LED light, which is not powerful but cheaper. Multi-mode fiber is used for short distances to connect devices in one building. The maximum distance depends on the data rate: for multi-mode fiber the max distance is 550 meters at 10Gbps, and 2km at 100mbps.
- Single-mode fiber optic cables use laser light, which is much more expensive. Single-mode fiber is used to connect devices over longer distances (up to 160 km).
- Unshielded twisted pair (UTP) copper cables need to be CAT5e or better. CAT is the short form of “category” for copper cables, which defines the thickness of the wire, the number of pairs (2 pairs or 4 pairs), and how tightly each pair is twisted.
