A-DQ(BN)2Y multi tube cable overview
This A-DQ(BN)2Y multi tube cable configuration is built with colored loose tubes stranded around a central strength member. The interstices are protected against water ingress, while the PE outer sheath adds UV and stress-crack resistance for outdoor service conditions. The dielectric structure also helps where metallic elements are not preferred.
Compared with metallic armored alternatives, this design focuses on a lighter all-dielectric structure while still addressing outdoor moisture exposure, duct routing and buried installation scenarios. If your project needs extra crush protection or a different jacket compound, alternative constructions are also available.
Key features of A-DQ(BN)2Y multi tube cable
Multi loose tube design
Suitable for higher fiber counts and organized fiber grouping in outdoor backbone applications.
Dielectric construction
Non-metallic structure supports use in electrically sensitive environments and helps reduce interference concerns.
Water blocking protection
Water-blocking elements and tube filling support long-term protection against moisture migration.
PE outer sheath
The PE jacket is suitable for outdoor use, UV exposure and demanding duct or buried routes.
A-DQ(BN)2Y multi tube applications
Outdoor duct installation
Suitable for campus, metro access, outside plant and inter-building routes installed in ducts and conduits.
Direct buried sections
Used where a duct is not available and the network design requires direct buried outdoor cable segments.
Access and backbone networks
Applicable in FTTC, FTTB, WAN, campus backbone and distribution-side telecommunication links.

How to select A-DQ(BN)2Y multi tube cable
1. Define the route
Confirm whether the cable will run in ducts, conduits or direct buried sections.
2. Confirm protection level
If the route needs higher crush or rodent protection, compare dielectric and armored alternatives.
3. Match fiber count
Select the required fiber count and fiber type according to backbone, access or distribution needs.
4. Review mechanical limits
Check tensile load, bending radius, outer diameter and installation conditions before final approval.
