What does the product code MOM DST U DQ(ZN) (SR)BH reveal about the cable’s construction?

The code designates a Multi-fibre Optical Micro-tight buffer cable with a dielectric central strength member, dry water-blocking, single-mode or multimode tight-buffered fibres, a corrugated steel wire armour layer (SR), and a low-smoke zero-halogen outer jacket (BH). The construction combines 900 µm tight-buffered strands stranded around a central element, aramid yarn strength members, steel wire armouring for mechanical and rodent protection, and an LSZH sheath that meets fire safety standards IEC 60332-1-2 and EN 50575.
