Top Factors To Understand About An Optical Transceiver

An optical transceiver is a fiber optic device using optical technology to send as well as receive data. Usually, the transceiver bears certain features that enhance its activities. These significant elements commonly utilized are such as fiber mode, wavelength, in addition to connector type. As the tech world continues to evolve, professionals and tech gurus must understand the importance of optical transceivers. Being the leading optical transceiver manufacturer across the world, we highlight some of the critical aspects you need to know about the device.

  1. An Optical transceiver helps to transmit large volumes of data over glass fiber.

An optical transceiver is commonly used in networks. They are better than copper because they have low latency, covering longer distances. Moreover, optical transceivers have high speeds. When they are plugged into switches and routers, they provide interchangeable solutions. Manufacturers agreed to work together to cut the cost of research, including Finisar, Juniper, and Cisco. 

They started with GBIC, which later evolved. Everyone knows that 100G is the hope of network development. Many people have expressed interest in 100G CFP optical transceivers, which led to an interest in 100G transceivers. It is prudent to understand the features of 100G before you decide to buy or design a product with it. 

  1. Fiber Mode

This is the most important type of fiber optical transceivers in the industry. It does an excellent job and is dependable. The two forms of fiber mode are single-mode and multimode. Multimode fibers come with core diameters ranging from 50 to 60 microns. Single-mode textures range between 8 to 9 microns. Multimode fibers come with a large aperture, which enables several modes of light to fit into the fiber.

Different modes of light work at different speeds when they travel down the fiber. Because multimode apps take a short time to reach and have affordable transmitters, they are used in multimode transceivers. OS1 is a common type of single-mode fiber. Although there are different types of single-mode fibers, the majority of optical transceivers are reserved for function over 0S1. Another thing to keep in mind about multimode transceivers is that they cannot deliver successful transmissions over single-mode fiber. 

  1. Transmission Distance

Optical transceivers transmit data at different speeds and distances. The main difference is that there are single-mode and multimode transceivers. In multimode apps, the type of fiber used and its transfer rate affects the transmission distance. Therefore, it is crucial to consider the two factors when using multimode transceivers. Other than that, you should know that the transfer rate dominates the transmission distance for single-mode applications. However, this differs from one vendor to another. The transmission distance determines the time needed to convey information.

  1. Wavelength

This is an infringed light employed in the transmission of data. It is used in fiber networks. It is the measurement of distance where optical transceivers send data at three different wavelengths. The wavelengths are 850nm, 1310mn, and 1550mn. They are popular because of the fiber optic rate is lower than them, and there is a standard for testing fiber optical at each wavelength. It is reliable because of the metered calibration.

Multimode fiber works at 850 nm or 1310 mn. On the other hand, single-mode fiber operates at 1550 nm. It is possible to reach a specific wavelength in a single-mode through built transmitters. Standardized schemes used are Dense Wavelength and Coarse Wavelength. Before you use any of these systems, you must understand how they work and what to expect.


This is the most used transceiver. It is efficient and is employed in several Gigabit Ethernets. It is the only one that supports 10 Gigabit Ethernet standard interfaces.

  1. X2

This is another type of optical transceiver. It primarily targets the XPAK market and is a small version of XENPAK. People want X2 and XPAK to merge, but there is a competition between the two. Infineon and Intel suggested the idea of combining the two. They thought that it was a good idea in the use of PCI apps because it complies with PC height.

XFP is a small version of 10 Gigabit Ethernet. It is not used most of the time because of its poor performance. Moreover, it is not mature like the rest of the MSAs. The good thing about XFP is that it has a big size and uses little power, compared to other MSAs. However, adopting XFP is complicated and takes time to complete.

  1. Matching Your Transceivers

You can also use optical fiber connections to match your transceivers. This ensures that light reaches the core. Now that you understand some of the applications of optical transceivers, it is vital to learn more about their classification. For starters, optical transceivers are categorized based on their connectors. There are four types of optic connectors, such as ST, LC, MPO, and SC. Similar to different types of transceivers, you should know where each connector applies. That way, you can and use it diligently. 

The majority of optical transceivers employ duplex connectors to operate. While one is used in transmitting data, the other is used for receiving information. The different types of connectors follow a code of colors. With that said, a connector that is compatible with a single-mode fiber is usually yellow. Those that are compatible with multimode fiber are gray, orange, or black. Once you know where these different colors apply, it becomes easy to understand connectors.


There are different types of optical transceivers, including CXP, CFP Series (CFP/CFP2/CFP4), QSFP28. In CXP, C stands for 12 in hexadecimal. GBIC- This is a large interface converter for transceivers. It is mostly used with fiber channel and Gigabit Ethernet. It gives a standard and electric interface to support physical media. It extends to hundreds of kilometers to reach the optical fiber. SFP- This is a small form factor that can be plugged into a device. It is used for data communications and telecommunications apps. It is an industry format enabled by various network components. They are meant to facilitate Gigabit Ethernet, SONET, and Fiber Channel. Others use it for communications standards.
