    I want to make a particle trails which resemble to travelling light in optical cable.

    So cable is transparent in the ending points and light travels through it.

    I've come with texture but I don't know how to set up shader/material for the trail.

    HDRP particle shaders

    How it should look like

    The Trails Module has a "Color over Trail" gradient that could be used to affect the color along the trail.
    For a shader, I'm not too familiar with HDRP or ShaderGraph, but I would hope there is an Additive option on the Unlit Master Node. I would try to use that.

    And a script that simulates + pauses the effect.
