Abstract

A flexible printed circuit board and optical network allocation device comprising same. The flexible printed circuit board comprises a circuit board body ( 1 ), a plurality of protruding interfaces ( 101 ) on the circuit board body, an adhesive layer ( 2 ) covering the upper surface of the circuit board body ( 1 ), components ( 102 ), and an uplink interface ( 103 ) used for information interaction with the components ( 102 ) on the circuit board body ( 1 ). Each protruding interface ( 101 ) is provided with an electronic label read/write interface ( 1011 ) used for reading electronic label information on an optical fiber head and an indicator ( 1012 ). The adhesive layer ( 2 ) is provided with an open window region ( 201 ) in the middle. The components ( 102 ) are immobilized on the upper surface of the circuit board body ( 1 ) and located in the open window region ( 201 ) of the adhesive layer, and are connected to the electronic label read/write interface ( 1011 ), the indicator ( 1012 ), and the uplink interface ( 103 ) respectively, used for controlling and monitoring the read/write information of the electronic label read/write interface ( 1011 ) and controlling on/off of the indicator ( 1012 ).
