What are the technical requirements need to provide customized PLC splitter?
(1) specify the fused biconical tapered (fiber-coupled type) PLC splitter. This PLC splitter production process is relatively simple, having better performance,has been widely used in CATV systems.
(2) determining the structure forms. Tends to use 19-inch rack, FC / APC or SC / APC connector in the engine room. If used in the tree network, You need to install and fuse the PLC splitter in the splice box without the cabinet and fitting, size is about 80mm * 60mm * 15mm (excluding leads to optical fiber).

(3) to determine the center wavelength and bandwidth. The wavelengths types divided into a single wavelength of 1310nm, single wavelength 1550nm, broadband-type(1310nm & 1550nm). Bandwidth types always classified to narrowband type ±20nm, broadband-type ±40nm. Under normal circumstances,we generally select a singlewavelength，narrowband type PLC splitter,not only meet using, but also cost savings.
(4) require additional loss limits are as follows:
Stars ones 2 3 4 5 6 7 8 9 10 11 12 16
Additional loss 0.2 0.3 0.4 0.45 0.5 0.55 0.6 0.7 0.8 0.9 1.0 1.2
(5) determine the splitting ratio, accurate to one decimal place, such as 82.3%.
