The core of the fiber-optic cable is made of one or multiple glass or plastic fibers. Central fibers are used as media for transmitting data, which is being sent in light beams from a laser or a LED. The core is surrounded by layer of plastic or glass with different density, which is called cladding. Its purpose is to reflect ...
Attenuation is being measured in dB/km, referring to the loss in signal strength or power of the light. Loss happens due the light traveling through the single-mode or multimode fiber.
There is a variety of wavelengths with which light is traveling. Original wavelength was 580 nm due to support of original LED and detector. As the technology was evolving, the 1310 ...
MDU - Multi Dwelling Unit EPON ONU's - are ONU's that usually will serve more than one subscriber, more than one home and unlike of SFU - Single Family Unit ONU, will be usually deployed at apartment building, a condominium complex or at the curbside - that is a scenario sometimes called FTTB or FTTC. And while in SFU case ...
According our statistics, Single Family Unit's, or SFU's are most popular EPON ONU's ordered and shipped worldwide, and it really does not depends on a market or country. Of course, types of SFU's vary.
For example as one classifier, SFU's can be divided in Indoor Type ONU's, or in Outdoor type. If we look at various business models used by FTTx ...
Some time ago we discussed Layer 1, or physical layer in PON communication systems. Now, in terms of OSI model, access network, and PON networks are access networks at it's best, exists at Layer 2. Because when we talk about Layer 2 - we usually mean Virtual Local Area Networks, or VLAN's, which is a core terms for Ethernet based ...

Differences Between FBT and PLC splitters
Also it is pretty clear visually shown on a infographic above (at least we hope so, as a lot of work are done to create above infograph), here's a description of what you can see above.
Optical networks require signal being splitted somewhere in design to serve for multiple ...
Can I use single mode equipment over multimode cable and vice versa?
This is a question we get many times from our customers. Especially common is a situation, in older installations, back to the times when multimode cable was cheaper than single mode, and inside buildings, and some last mile installations were planned so, that multimode cables were laid.
Answer is not ...
