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 ...
Apart from a regular scheme with series of 1:N splitters in FDN, some networks, especially those with industrial grade for power, gas or electricity providers, require equipment and some network design skills to provide backup schemes for your PON network.
Theoretically there is a 3 ways to provide such kind of backups:
1. Protecting fiber damage - in this case 2:N type ...
Network designer require to consider type of media transmission depending on network needs. Different media have different specifications for throughput, cost, noise immunity, size, and scalability.
Throughput
Throughput is one of the main factors for choosing transmission method. While in theory signal can travel with speed of light, in practice it is limited by media physical characteristics and multiplexing techniques. Since the ...
Term “latency” is referring to a delay between transmission and receipt of the signal. In the electric cable there is time difference happening between time when user press the button and moment when server receives signal. Many physical factors are affecting latency, such as length of the wire/cable and amount of nodes between server and signal sender. Different devices for ...
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 ...
What are the differences between Point to Point vs Point to Multipoint Communication Schemes? When do you choose Point to Point and when - Point to Multipoint?
Of course, everything comes down not only for a type of services and network you are planning and building (Is it LAN, WAN or MAN?) and also it's type - Access, Core, Last Mile?
Different types of transmissions ...
What is Time Division Multiplexing? Supporting our customers daily, we sometimes get this question, and mostly because various references mention, that EPON and GPON protocols use TDM - Time Division Multiplexing in a direction from ONU to OLT. We also discuss that more in details in this article, which talks about Layer 1 structure in GPON/EPON.
To understand this, let's answer the ...
FDM multiplexing
What are main differences of WDM vs FDM multiplexing? Let us delve in details.
In this type of multiplexing, every subchannel is having its own frequency band, which is the reason technology is called frequency division multiplexing. Each subchannel has been modulated with different frequencies before being multiplexed to the single channel. It allows usage of single line for up ...
Baseband is type of transmission that is using current to send signal over the wire as digital wave. It can transmit only one signal at a time, due to requirement of the exclusive use of the wire. This type of transmission is allowing only on device to transmit in the network at one time, while other devices need to wait ...
Every network has its capacity or bandwidth. This constant defines amount of data that can be transmitted in one second. Sometimes it is called bandwidth (although there are different uses of term bandwidth in networking). The data throughput is measured in amount of bits transmitted per one second. The prefixes define amount of zeros after the number - kilobits for ...
