How Does a Good Optical Transceiver Look?


When shopping around for an optical transceiver module, as an end-user, you should not only consider the stability of the device but its reliability and characteristics too. Price and quality are also some of the elements you should consider checking when selecting a reliable optical transceiver module. Hopefully, this blog post will help guide you when it comes to dealing with an optical transceiver manufacturer.

1. Maximum Transmission Distance

Different optical transceivers support different transmission distances. Generally, the transmission distance of the optical transceiver is shorter than one mode of the optical transceiver. The price is also slightly lower, making it affordable in many cases.

For instance, 10GBASE-SR SFP optical transceivers can reach about 300m while the 10GBASE-ZR SFP can hit 80km. For that reason, it is crucial to determine the total distance needed for transmission.

Besides taking into account the general attenuation as well as dispersion of the optical signals in the process of transmission, it is highly recommended that you make great use of optical transceivers that can support larger transmission distances than what you may need.

For a short-haul connection between major devices, you should use a product with a relatively high-speed cable. This should be cheaper than the general optical transceiver module.

2. The Operating Temperature

The general operating temperature of the environment within which you put optical transceiver matters. It should neither be too high or too low as this may lead to failure.

The temperature ranges of the normal commercial transceiver are about 0 to 70 degrees Celsius. The industrial transceiver is, however, perfect for the temp range of about 40-75 degrees Celsius.

3. Check the Wavelength

Most of the deployed fiber-optic links use about two fibers for every link, with one for every traffic direction. The transceivers for these links devote a single fiber for one receiver.

The other fiber is then directed to traffic. Single-fiber transceivers that collapse the directional traffic to a single-mode fiber that uses one or two wavelengths for the full-duplex operation are still in use.

Particularly, the single-fiber wavelength transceivers have been readily available but did not really exploit their inherent advantages.

The commonly used wavelengths include:

· 1550nm, which is a single mode. This is a single loss transmission that is generally used for smaller machines

· The 850nm, which is a low-cost option with a shorter transmission distance of about 500m

4. Quality as well as the after-sales services  

Then there is the service life of an optical transceiver, which is about 5 years. It is important to note that it is always difficult to see some good in the first year. This should be notable in the second year of use because issues can arise at that time.

Final Thoughts

The stated tips above should be considered when selecting the right optical transceiver module. Besides, it would help if you also weighed the options of getting a connector and a fiber. Experts in this industry are happy to provide a broad range of optical transceivers as well as fiber optic solutions to help meet your needs.
