High speed SFP transceivers

Technology Services


Transceivers are one of the most widely used electronic devices in the world today. They are essentially an amalgamation of a transmitter and receiver. The transmitter is a device which is used to relay messages in the form of radio waves. Receivers on the other hand are electronic devices which concern themselves with receiving or catching these radio waves and covering them into useful messages or information. With the combination of both of these devices into one, transceivers today have a variety of use in different aspects in the electronics and telecommunication field.

SFP Transceivers

Small form factor pluggable of SFP transceivers are the latest versions of transceivers. They are highly useful because of their compact nature and hot plugging property. Hot plugging refers to the process of switching or changing various devices or components on a circuit without stopping the electricity or shutting the system down. This form of a transceiver is widely supported by experts across the globe who have helped in developing the particular device. With these SFP transceivers, higher quality devices are also made. The first ever SFP+ transceiver models would be limited to a speed of only 1 giga bits per second. Though it seemed to be a pretty fast speed back then, technology has developed rapidly to introduce new formats of these devices which offer much higher speeds. The enhanced form of this SFP transceiver, which 10G Dual Fiber SFP+ Transceiveris also called 10G SFP+ or the SFP+ Transceiver, offered much more high speed ranging up to 10 giga bits per second. After the 10G SFP+ transceiver, came the even better SFP28 version. This format of the SFP+ transceiver gave the user to deal with data at about 25 giga bytes per second. An even larger product came into the market soon. This device has a four lane system and is called the Quad Small form factor pluggable or QSFP transceiver. With the addition of more lanes, the device offered up to four times more speed than that was offered by its corresponding SFP version. For example, the QSFP28 offered speeds which reached 100 giga bits per second, which is four times the speed offered by its corresponding SPF28 version.

The 10G SFP+ or simply SFP+ transceiver variants were introduced around 2009. They also have direct attaching platforms for connecting two 10G SFP+ ports. These cables which attach directly can be of varying lengths such as 7 meters, called the passive variant, 15 meters which are the active variants and the 100 meters, called the active optical variant.

Properties of SFP transceivers

The main reason why people choose these 10G SFP+ or other higher SFP+ transceiver models is because of their tough exteriors and also protection from electromagnetic interference or EMI in short. Also, power dissipated is quite low, lesser than 1 watt in some cases. Moreover, transmission distances can be up to 80 km in some devices.


We clearly see that transceivers are an important component in electronic devices. Now, with the advancement of technology, electronic devices too can become more and more advanced and of much better quality.
