The utility model provides a stealthy optical cable of readily releasable type relates to communications optical cable technical field. The optical cable includes a plurality of sub - cable units and sets up the outer jacket in a plurality of sub - cable units outside, and every sub - cable unit includes that optical fiber unit, an even number symmetry set up in the first reinforcement of optical fiber unit both sides and wrap up in the sheath of optical fiber unit and first reinforcement outside, and optical fiber unit includes optic fibre and set up the transparent tight cover outside optic fibre, and a plurality of recesses have been seted up to the sheath, and a plurality of recess symmetries set up in the both sides of sheath, the outer jacket is embedded to be equipped with a plurality of second reinforcements, and the surface of outer jacket is provided with to open shells the arch. It has better high and low temperature performance and mechanical properties, and the optical cable is opened and is shelled the separation of easy, sub - cable easily, and not fragile, the easy branch of its optic fibre has solved the problem that the wiring resulted in aesthetic problems behind the fiber to the house simultaneously.
