7 Tips For Selecting A Proper Fiber Optic Transceiver

By the term "fiber optic transceiver" we actually refer to a device which makes use of fiber optical technology for sending and receiving information. There are electronic components in the transceiver for conditioning and encoding or decoding the information into light pulses and sending them as electronic signals to the other end. It actually employs a light source for sending information as light which is operated by the electric components and it likewise takes the help of a photodiode semiconductor for receiving the light pulses. One such well-known transceiver happens to be the Cisco GLC LH SMD which is used in storage, IP network and also LAN.


The majority of the transceivers have got a couple of ports intended for bidirectional communication since it is not possible for data to travel in both directions at the same time within a fiber optic cable. On the other hand, although it might be effective to use a single cable it will be able to either send or receive data and not both. There is a special connector at the reverse end of the transceiver for fitting it into particular types of business-quality firewalls, routers, network interface cards as well as Ethernet switches. A contemporary fiber optic transceiver is mainly supposed to plug into the previously mentioned network devices and therefore it is a rather compact device; we call this sort of transceiver a compact form-factor transceiver.

Just like most of the devices out there, you will come across lots of types and models of transceivers on the market that varies widely in different aspects including performance, size as well as price.

It is known to most of us that there are several reputed brands out there which fall in this optical communication sector, namely, H3C, Cisco, and Huawei. Now the question that might arise is that whether it is the price or the brand that must be taken into consideration while going for one of these products. Nevertheless, it appears to us that it is the performance of the products which is more important. At present, compatibility is taken more seriously by the majority of the users given that these fiber optic transceivers happen to be extremely pricey and it is not possible to make use of the second-hand products for more than a year or so in spite of their rather inexpensive rate. As a matter of fact, there is a significant difference in the prices as well as the performance of these products in spite of them getting popular day by day and the main reason for this is that different manufacturers make use of different techniques as well as chips.

In the subsequent paragraphs, we have mentioned 7 useful guidelines which will help you to get hold of the most competent fiber optic transceiver on the market.

1. Take into consideration the fiber's construction

Although you'll come across some particular varieties of internal construction, it is imperative to go for the one which will cater to your needs the most. The tight pack is definitely one of the most well-known types out there. The fanout design happens to be the other type of construction which offers its personal jacket to every single buffered fiber and can likewise boast of a more resilient design.

One more type of internet construction happens to be the zip cord which is definitely amongst the most recommended internal construction choices. Here, only a couple of buffered fibers should be considered in the individual jackets.

The flame resistance level ought to be the last factor that should be considered. It is important to bear in mind that as many as 3 different grades are available, namely, special, general, and high. It is possible to figure out the flame resistance level by means of different tests which include those that determine flame propagation as well as smoke density values.

2. After-sales service

In most cases, it is possible to use these transceivers for a minimum of five years. One will not be able to understand their performance level until a couple of years have passed. Consequently, it is imperative to go for providers who offer you an extended warranty while purchasing these products. Also, you must comprehend the fact that the after-sales service is extremely important when it comes to affordability in case it is not your first purchase. It will give you a fantastic opportunity to figure out whether you made the right decision in case you face trouble with the device. Therefore, try to take advantage of your experience regarding the after-sales services which will definitely prove to be useful for you in the long run.

3. Verify the network compatibility

Make it a point to give special emphasis on the networking issues as well as the type of Optical Transceiver chosen by you. Bear in mind that there are lots of different types on the market which have been manufactured by different companies. No two transceiver is identical to each other given that every single company has got its own personal production style. Alternatively, users have been using various types of networks and verifying the conditions, as well as system requirements, will definitely be a wise idea while purchasing the product.

4. Figure out whether you require half-duplex or full-duplex

There are several chips which will only make use of full-duplex configuration and selecting them with half-duplex mode might result in a loss as well as conflict. Go for full-duplex unless you believe that your application has the ability to support half-duplex.

5. The fiber mode

Fiber is available in two basic types, namely, single mode and multimode. Single mode fiber is mainly intended for longer distances of transmission which is employed by applications that require bandwidth traveling over long distances. On the other hand, the multimode fiber is appropriate for shorter transmission distances and is mainly used by the LAN systems as well as video surveillance.

6. Compatibility and temperature adaptation

Although the different types of optic transceivers are becoming more advanced day by day, the network is getting affected to some extent by the compatibility between these transceivers. It is good to know that compatibility isn't an issue so long as the products are standardized in terms of the related global criteria and are also accredited by FCC. Since the temperature generated within these transceivers is rather low, they are used extensively in the computer room as well as switches which force the temperature to become high or lower. While it becomes too low or too high it is going to influence the parameters including optical sensitivity and optical power.

7. Consider the data transmission distance

The fiber optic transceivers are not going to transfer the identical distance. Usually, a single-mode transceiver has got longer transfer distance whereas the multimode ones come with shorter transfer distance. Having a proper knowledge regarding the transfer distance will assist you in easily selecting the transceiver which will be suitable for your network demands. Besides this, it will also be a wise decision to consider the attenuation as well as the dispersion at the time of transmission while calculating the distance.


It is not at all easy to figure out the most competent optical fiber transceiver. It is imperative to take into account the fiber mode, internal construction, fiber cable jackets and also the flame resistance levels along with other factors while buying the transceivers. Coming across the appropriate fiber transceiver should not be difficult in case you perform the required research.
