What is the comparison between centralized and cascading distributions?

 

Centralized distribution network

The centralized distribution generally adopts a combined distribution ratio of 1:64, a 1:2 splitter at the central office, and a cabinet of 1:32. These single-stage fiber splitters can be placed in multiple locations in the network or installed in a central location. But in most cases, centralized fiber splitters are placed in external equipment (OSPs) to reduce the total amount of fiber required. OLT (Optical Line Termination) active ports in the central office (CO) will connect/splice to the fiber leaving the CO. This fiber is reached through different closures to the input port of the fiber splitter, which is usually placed in the cabinet. The output port of this fiber splitter enters the FTTH distribution network and reaches the home of the potential customer through different closed devices and indoor/outdoor terminal boxes called ONTs (Optical Network Terminals). Therefore, in this centralized split topology, PON connects one OLT port to 32 ONTs.

 

Cascading distribution

Unlike centralized tap topologies, the cascade tap method does not have fiber splitters in the central office. The OLT port is directly connected/spliced to an external plant fiber. The first stage diverter (1:4 or 1:8) is installed in an enclosed place not far from the central office. The input of the first-stage fiber splitter is connected to the OLT fiber from the central office. The second stage fiber splitter (1:16 or 1:8) is located in a terminal box, very close to the customer's location, and each splitter covers 8 to 16 homes. The input to these PON splitters is the fiber from the output of the first stage splitter described above.

 

What is a PLC splitter?

PLC splitters are passive devices, also known as optical splitters, which do not require external energy, as long as there is input light. The splitter consists of incident and exit slits, mirrors and dispersive elements whose role is to separate the required resonance absorption lines. The key component of the splitter is the dispersion element, and commercial instruments now use gratings.

1) After the light enters the splitter, the ordinary light can be divided into the following three categories according to the wavelength:

Near ultraviolet (near UV): 200-380nm.

Vacuum ultraviolet (vacuumUV): 10-200nm.

Extreme UV, extreme UV: 1-10nm.

2) From the perspective of human health and environmental protection, it can also be divided into UVA (315~400nm), UVB (280~315nm), UVC (below 280nm).

3) Another classification method is single-mode, multi-mode.

Single mode: 1310nm. Multimode: 850nm.

There are three general interfaces for optical splitters, one is LC, one is FC, and the third is SC

Is a splitter similar to a switch? What is the difference between the two？

Optical splitters are not similar to switches, and the differences are as follows:

First, the subject is different

1. Optical splitter: is a passive device, does not need external energy, as long as there is input light.

 

2. Switch: It is a network device used for electrical (optical) signal forwarding.

Second, the role is different

1. Beamsplitter: It is composed of incident and exit slits, mirrors and dispersive elements, and its function is to separate the required resonance absorption lines.

2. Switch: It can provide an exclusive electrical signal path for any two network nodes accessing the switch.

Third, the characteristics are different

1. Optical splitter: optical fiber convergence device with multiple input ends and multiple output ends, often used for coupling, branching and distribution of optical signals.

2. Switch: It is a device that completes the information exchange function in the communication system and is applied in the data link layer. The switch has multiple ports, each with bridging capabilities.

Packing & Shipping

 

On the one hand, plastic blister bag package is preferred by European customers, because it can protect the plc splitters from crashing and keep goods well during transportation; or for dealers, the fine plastic blister bags will be liked by the end user.

 

On the other hand, if you prefer a cheaper shipping cost, and the plc splitters are used for project, the PE poly bag is a good choice.
