Splice tray and fiber management system

A splice tray, comprising:

• a base tray including an optical splitting area, a splice area, and a coiling storage area that are formed in the base tray, the splice area is configured for optical fiber splicing, and the coiling storage area is configured for optical fiber coiling storage;
• and
• a mounting port for mounting an optical splitter is provided in the optical splitting area, the mounting port has a first inner wall and a second inner wall facing each other, a support structure connected to the base tray is disposed between the first inner wall and the second inner wall, a weak portion is formed at a junction between the support structure and the base tray, and the weak portion configured to selectively break or deform the support structure to adjust a size of the mounting port along a direction from the first inner wall to the second inner wall, to fit the optical splitter.
