Thinking About Fiber Optic Transceiver? Reasons Why It’s Time To Stop!

Fiber Optic Transceiver

Fiber Optical Transceiver is a fiber optic technology that transfers data over a beam of light. This technology is the most efficient and reliable for analogue and digital overhead transmission, especially for long distance. >

In recent years, fiber optic transceiver technologies have been increasingly applied to numerous common device-to-device and device-to-network communications services. To achieve a wide variety of interesting applications, fiber optic transceiver technologies require an increasing range of modules with a large number of integrated high-quality components. Fiber optic transceivers are suitable for all fiber-optic networks, which makes the market bigger. Perhaps it’s time to know what’s exactly is the FOT?

The A – Z Of Fiber Optic Transceiver

Fiber optic transceivers can be generally referred to the optoelectronic devices which are combined with optical fiber transmission via the transmitter and receiver. The fiber optic transceiver usually includes 2 basic parts: transmitter & receiver. This is a kind of connector with digital signal processing functions. A fiber optic transceiver (or optical module) will convert an electrical signal into an optical signal or vice versa through the optical fiber cable transmission.    

The transceiver is a device that receives and sends data as light pulses. It’s capable of emitting and receiving optical signals, converting them into electronic signals. This is done through the use of a light-emitting diode and a photodiode semiconductor.

Fiber Optic Transceivers Are Available In a Variety of Configurations

Fiber Optic Transceivers are grouped into several categories to satisfy a variety of needs.

· Sorted based on transmission rates

The transmission rate can be expressed in terms of upload or download speed. You can then use the bits transmitted per second to calculate the unit of measure for transmission rate in Megabits per second, or Mbps. The transmission rate specifies how fast data can be exchanged or transmitted through a fiber optic transceiver. Fiber optic transceivers are critical to this process because they convert digital data into light signals that pass through different networks.

· Package-based classification

Different fiber optic transceiver packages are made for different types of telecommunications equipment. Generally, the sizes range from 12 to 100 gigabits per second. They are classified by their connector type and bandwidth (the number of bits transmitted per second). Some of these are QSFP, QSFP28, CFP, and CFP2, as well as CFP4, with many more.

· Fiber mode categories

Fiber optic transceivers are used to connect an optical fiber to fiber optic equipment. As the characteristics of single-mode fiber as well as multi-mode fiber are different, the successful network connection depends on the types of transceivers being used. The multi-mode transceiver is commonly used for a short distance such as 0.5 kilometers to 2 kilometers. The transmission distance of the multi-mode transceiver may be up to 10 kilometers to 160 kilometers.

· Transceivers  based on applications

There are several different transceivers, and they can be used for different applications. For instance, SONET/SDH transceivers can be used for Ethernet or CPRI networks, and mobile devices use LTE transceivers.

The Ultimate Guide To Fiber Optic Transceiver Key Parameters

Distance of transmission: Fiber optic transceivers transmit light between two locations across an optical fiber. The maximum distance over which optical signals can transmit is dictated by the wavelength of the light used in the transmission and the quality of the fiber. The generic optical transceiver overcomes the limitation of the 10 kilometers transmission distance. It can be extended up to 20 kilometers if two fiber pigtails are used.

Central wavelength: Fiber optic transceiver modules are commonly used in high-speed data transmission. The optical central wavelength, which is the determining factor in signal transmission, is calculated through the central wavelength of the fiber + plastic/glass connector interface band shaping effects. Three of the most common central wavelengths used in fiber optic communication systems are 850 nm, 1310 nm, and 1550 nm.

Power of optical transmission: Optical power is a basic metric that can be measured on a network transceiver. It tells you how much signal is being transmitted from one end of the connection to another, and it also lets you know if there are any issues with the equipment. When measuring optical power, ensure that both ends have similar measurements – if one transceiver has a lower output than the other, there might be an issue with the equipment or a connection between them.

Sensitivity in receiving: This is used to describe how well a fiber optic transceiver can receive signals. It determines the maximum range of the signal, as well as the amount of noise that can be tolerated by the system. It is measured in decibels relative to 1 milliwatt (dBm).

Fiber mode: Optical fibers come in two varieties. Multi-mode optical fibers have larger cores, which means that more than one ray of light can pass through a single fiber. This increases the bandwidth of a single fiber, but at the expense of signal loss and misdirection. Single-mode optical fibers have smaller cores, so only one ray of light can pass through a single fiber. Single-mode is best for long-distance data transmission, while multi-mode is sufficient for most consumer and commercial projects with shorter distances.

Connector Type: Optical transceivers come with a variety of connectors to accommodate the different types of optical fiber cables. The most common type is the LC connector, which can be used to connect a variety of transceivers including QSFP, SFP, SFP+, SFF, and XFP transceivers.

Extinction ratio: The extinction ratio is the amount of optical signal that gets through unscathed when there is no signal (signal 1 and signal 0). It indicates the capability of an optical module to distinguish between two signals; the higher the ratio, the more likely it is for your signal to come through.

Little Known Fact about Fiber Optic Transceiver – And Why It Matter


Wavelength-division multiplexing fiber optic transceivers (WDM transceivers) and dense and coarse WDM networks help enable long-reach, metro, and short-haul high bandwidth optical transmission. Manufacturers produce them in a range of form factors to suit a variety of applications, including Ethernet and Fiber Channel services.

WDM transceivers are similar to GbE transceivers in that they handle various types of data. However, WDMs are used with different wavelengths of light. These are split into two sections: one for coarse data, which is data that does not have to be sent at high speeds, and dense WDM, which handles high-speed data.
