Optical module

Abstract

The present disclosure describes an optical module. The optical module includes a housing comprising a first portion, a second portion, and protrusions, and the protrusions are configured to enclose the first portion to isolate the first portion from the second portion. The optical module includes a circuit board disposed inside the housing, the circuit board comprising a first area, a second area, and a metal strip attaching to the protrusions. The optical module further includes an indicator light configured to emit light and a laser driving chip. The first area of the circuit board is electrically connected to the indicator light to supply power to the indicator light. The second area of the circuit board is electrically connected to the laser driving chip. The metal strip encloses the first area to isolate the first area from the second area.
