1.PLC Splitters internal structure
l PLC products are composed of three parts：Input FA、Chip、Output FA.
As picture 1
l The structure of FA
FA including the cover plate, substrate, fiber soft adhesive, hard adhesive. As picture 1
Soft adhesive:It is used to fix the optical fiber on the FA cover plate and substrate and protect the optical fiber from damage
Hard adhesive:Fixed the fiber where among the cover plate,substrate plate and V-groove inside.
Ø V- groove is a V-shaped groove evenly distributed on FA substrate plate for placing and fixing bare optical fiber.
Ø According to the number of channels, V-groove can be divided into 2CH, 4CH, 8CH, 16CH, 32ch, etc.
Ø According to the number of waveguide width ,V-groove can be divided into 127um and 250um .
l SPL Chip
As picture1，SPL chip made up chip and cover plate.
Ø The kinds of chip
According to the number of channels, it can be divided into 1x8、1x16、2x8, etc.
According to the angle:usually divided into + 8 ° and - 8 ° chips..
Ø Waveguide distribution
l Polishing angle
+8°’s chip and FA
Ø -8°’s chip and FA
1.PLC splitter classification
According to the number of product input and output channels, it can be divided into 1x2, 1 * 4, 1 * 32, 1 * 4, etc.
l Encapsulation type
According to different packaging processes or methods, PLC splitter is usually divided into the following five types.
Ø Splitter encapsulation—— Splitter
Ø Branch encapsulation——Fan-out
Ø Mini module encapsulation ——BL
Ø Module encapsulation——Module
Ø Chassis encapsulation——Chassis/Panel
1.PLC Product optical parameters
Ø Insertion loss（IL） The relative variation of the output optical power with respect to the input optical power.
Mathematical expression IL=-10lg（Pout/Pin）
Ø Return loss（RL） The relative change of reflected optical power relative to input optical power.
Mathematical expression IL=-10lg（Pref/Pin）
Ø Uniformity(UNI) To measure the difference in performance between different channels of a device, usually expressed as
Ø Directional (DIR) Measure the signal crosstalk degree between each channel of the device.
Mathematical expression IL=-10lg（Pout ch2/Pin ch1）
Ø Temperature dependent loss（TDL）Maximum change of product IL under different temperature conditions.
Ø Wavelength dependent loss（WDL）The maximum variation of product IL at different wavelengths.
Ø Polarization dependent loss（PDL） The ratio of the maximum transmission to the minimum transmission in a polarized state.
Inside Tmax and Tmin represent the maximum and minimum transmission of DUT respectively.
