Have you ever experienced a situation when after arriving at the installation site and inserting a transceiver into an appropriate port of a switch or a router with the aim of setting up a fibre-optic link you unexpectedly saw a notice: “transceiver unsupported”? I think I can guess the words you uttered then, but to avoid bad language I will not attempt to say them.

After a while, when you finally calmed down, you had to face the truth … and make a trip back to the warehouse, exchange the transceiver and make another trip. Finally, the link worked… but what did your calendar look like after that?

In such cases, we usually reflect on the problem by asking questions: Why did it happen? Who is to be blamed? And again, a number of people spend their precious time identifying the reason. Was it the designer? Was the information about the network inventory system incomplete? Or maybe the sales department didn’t discuss all details with the client?

How about remodelling the entire system? Wouldn’t it be much easier if you could take a universal transceiver from the warehouse and install it in the device? Of course! It would make the life easier for the sales department, designers, warehouse staff, engineers… But does an ‘ideal’ transceiver exist? How much does it cost? Is it economical?


Perhaps creating a universal transceiver in a situation where there are several interfaces like SFP, SFP+, QSFP, QSFP28 and a variety of transceiver types like SR, LR, ER, ZR would be pretty expensive and would affect the price of the transceiver.

So, let’s analyse what should be done to find a better solution. The transceiver that is to work with a specific device is installed in the device at the very last stage of the entire chain of design and sales processes. As producing a universal transceiver would be too expensive, maybe we should focus on the person who is the last to “touch” the transceiver and equip them in adequate tools that will adjust the transceiver to work with any network device just by one click…


When thinking of such a device, you might have both questions and doubts. Every few months there appear new versions of devices and new interfaces, so even if you had such a device, you would have to update it on and on…

But what if such a device was connected to the provider’s cloud computing that is updated in the real time and operated remotely when necessary by a qualified engineer, and to use it you would just need a laptop with a USB port and an access to the Internet to do it?

You can get all this and much more from GBC Photonics. The device described above exists and is known as a Simple Recode Device (SRD). It enables you to alter the configuration of optical modules, diagnose problems, alter the wavelength and many more!

How can you benefit from SRD?

  • Thanks to this device you can stock universal transceivers – you can adjust them for you purpose just before the installation;
  • Your engineer will not have to go to the installation site so many times. Every trip generates unnecessary costs;
  • Your designer or sales engineer will not have to ask your client about the device type in which the transceiver is to be installed;
  • And finally, you will earn much more!
  • GBC Photonics constantly undertakes research projects and develops its products so that they can work for you, not you for them.
