What is an SFP optical module?
SFP optical module is a one billion - bit electrical signals into optical signal interface device, is the industry standard of small pluggable gigabit optical transceiver module, integrated pluggable in switches, routers and other network equipment, media converter SFP ports, used to connect to the light or copper cables for data transmission network, we can usually in Ethernet switches, routers, firewalls, and find it in the network interface card.
What is an SFP port?
As mentioned above, SFP ports are common on switches, routers, media converters and other network devices. Do you really know SFP ports? The SFP port is mainly used for signal conversion and data transmission. The port conforms to the IEEE 802.3ab standard (such as 1000base-t), and the maximum transmission distance is up to 1000Mbps (the switch's SFP port supports 100/1000mbps).
SFP port advantages
The SFP port is a hot-pluggable I/O interface (refers to the input/output interface), which has strong flexibility and is suitable for a variety of products, such as 1000base-sx, 1000base-lx/LH, 1000base-zx or 1000base-bx10-d/U ports for exchange. In addition, the SFP port can be compatible backwards, supporting 10/100/1000mbps.
SFP port for gigabit switch
Gigabit switches SFP port can be connected to various types of optical fiber by single-mode and multimode fiber (for example) and network jumper (cat5e and cat6, for example) used to expand the exchange of the entire network function, but gigabit switches SFP port before use must first insert the SFP optical module, and then use fiber optic jumper wire jumper wire and network for data transmission. All enterprise-class switches on the market today have at least two SFP ports that can be used to build ring or star network topologies between different buildings, floors, or areas through fiber optic and cable connections such as network hoppers.
