FTTH Plug-in Splitter PON
In the fiber-to-the-home FTTH network, the plug-in splitter is the core component of the passive optical network (PON), which is responsible for the efficient distribution of optical signals and is the central computer room of the connecting operator
A plug-in splitter is a passive device that can proportionally distribute one input optical signal into multiple outputs (or vice versa, converge multiple inputs into one output). Its "plug-in" design refers to a pluggable structure that can be directly installed in the slots of optical fiber splitter boxes, distribution frames and other equipment, without complex wiring or welding, which greatly simplifies network deployment and post-maintenance
product parameters
1. Connector type, common ones are SC, FC, ST, LC, etc. Connector end face types are UPC, APC, etc., which can be selected according to actual needs.
2, splitting ratio: common ones are 1:2, 1:4, 1:8, 1:16, 1:32, etc. Users can choose the appropriate splitting ratio according to actual needs to ensure the reasonable distribution of signals.
3, insertion loss: different splitting ratios of insert-type splitters have different insertion losses,
4, splitting uniformity: refers to the difference in optical power of each output port, the smaller the value, the better. A better chip splitter can control the uniformity of the splitter 5, at a lower level, to ensure that the output optical power of each port is more consistent, so that the signal quality received by each user terminal is similar.
6, return loss: PC type 45dB, UPC type 50dB, APC type 60dB are generally required. High return loss value means that the splitter loses less when the signal is returned, which can ensure the signal quality.
7, working wavelength: Usually the working wavelength range is 1260nm-1650nm, which can meet the common optical fiber communication wavelength requirements such as 1310nm and 1490nm, and is suitable for a variety of optical fiber communication systems.
8, working temperature: generally required in the range of -40 ℃ to + 85 ℃, so that the stability of the equipment can be guaranteed under different environmental conditions, so that it can adapt to a variety of indoor and outdoor environments.
