Abstract:
A multichannel optical transmission device, comprising:a transmission unit having: a covering area; and useful lasers with optically active zones, said useful lasers disposed in a row, said optically active zones emitting useful radiation vertically with respect to said covering area when said useful lasers are driven; and a monitor unit having: a monitor receiver with a radiation-sensitive area, said monitor receiver disposed on a plane lying above said covering area; at least one monitoring laser with an optically active monitoring zone, said at least one monitoring laser disposed at said row of useful lasers, said optically active monitoring zone emitting radiation perpendicular to said covering area, at least a part of said radiation passing to said radiation-sensitive area when said at least one monitoring laser is driven; said monitor receiver projecting above said at least one monitoring laser as a cantilever support to place said radiation-sensitive area opposite said optically active monitoring zone; said optically active monitoring zone and said radiation-sensitive area defining a space therebetween; and a plastic transmissive to said radiation filling said space.
