Made in the most convenient form for use - that is, a male-female adapter. Such a silencer, unlike the adapter silencer, does not require installation in the distribution box. It can be conveniently and easily mounted in the optical path by attaching it to the end of the patch cord. When it is not needed, its disassembly is also simple.

 

It should be remembered that it is best when the attenuator on the optical path is mounted in front of the receiving device. So on the RX line.
