Central loose tube
A 3.0 mm PBT tube houses the optical fibers in thixotropic gel. This separates the fibers from the outer reinforcement while the filling material limits moisture movement within the tube.

CLT Non-Metallic Armored Fiber Optic Cable
CLT non-metallic armored fiber optic cable uses a gel-filled central loose tube, water-blocking glass yarn reinforcement and a UV-resistant PE jacket for outdoor access and distribution links. The published A-DQ(BN)2Y-CLT construction covers 2, 4, 6, 8 and 12 fibers.
Choose this compact, all-dielectric cable where a duct or conduit route needs mechanical reinforcement without steel armor. Glass yarn provides tensile support and rodent resistance; it does not make the cable rodent-proof.

Non-Metallic Armored Cable Construction
Glass yarn reinforcement
Water-blocking glass yarn surrounds the tube and carries tensile load. There is no corrugated steel tape in this construction, so the cable contains no metallic armor.
Single PE jacket
The polyethylene sheath resists UV exposure and stress cracking. Ripcords assist jacket opening during preparation for splicing. LSZH and L-M-HDPE sheath options are listed on request and require a configuration-specific quotation.
Outdoor Access and Distribution Applications
Duct and conduit links
Use the CLT construction for low-fiber-count access links, secondary distribution and inter-building voice or data routes installed in ducts or conduits.
Campus and industrial networks
Connect distribution boxes, frames and customer-side panels where a compact all-dielectric cable fits the route and published mechanical limits.
For building entry and indoor sections, specify the required fire performance and jacket material. Do not treat the standard PE version as an LSZH or CPR-classified cable. Aerial suspension and direct burial suitability require project-specific confirmation.

Optical values in the datasheet
The PDF lists multimode attenuation at 850 and 1300 nm. These are wavelengths, not bandwidth values. Single-mode options and their attenuation limits should be specified in the RFQ rather than inferred from this table.
| Fiber type | Core / cladding | Wavelength | Maximum attenuation |
|---|---|---|---|
| OM1 | 62.5/125 µm | 850 / 1300 nm | 3.2 / 1.2 dB/km respectively |
| OM2 | 50/125 µm | 850 / 1300 nm | 3.0 / 1.0 dB/km respectively |
| OM3 | 50/125 µm | 850 / 1300 nm | 2.8 / 0.8 dB/km respectively |
| OM4 | 50/125 µm | 850 / 1300 nm | 2.7 / 0.7 dB/km respectively |
How to Specify A-DQ(BN)2Y-CLT
- Define the route: duct or conduit dimensions, pulling sections, bends and environmental exposure.
- Select the fiber: required count, single-mode or multimode type and optical loss budget.
- Check mechanical limits: 1200 N installation tension, 800 N permanent load and the published bend radius. Installation equipment must stay within these limits.
- Specify the sheath: PE for the published outdoor version; request a separate LSZH or L-M-HDPE configuration when needed.
- Complete the RFQ: total length, drum length, jacket color, fiber identification, cable printing, fire requirements and delivery destination.
Compliance and jacket selection
The PDF cites the IEC 60794 family for cable tests and lists IEC 60754-1, IEC 61034-1/2 and IEC 60332-1 references. These references do not establish a fire class for every sheath option. Request the applicable test evidence and, where required, a configuration-specific Declaration of Performance.

CLT Non-Metallic Armored Cable FAQ
Does this cable contain steel armor?
No. The published A-DQ(BN)2Y-CLT uses glass yarn reinforcement and a PE sheath. Choose a separately specified steel-armored construction if the route calls for metallic armor.
How many fibers are covered by the datasheet?
The linked PDF lists 2, 4, 6, 8 and 12 fibers. Counts outside this range need a separately confirmed construction and datasheet.
Can the standard PE cable be used inside a building?
Confirm the fire requirements for the indoor section before selection. The standard PE construction must not be presented as equivalent to an LSZH option or as carrying an unverified CPR class.
What bending radius should I use?
The PDF specifies 20 times the outer diameter. For the published 7.0 mm cable, this equals 140 mm. Confirm installation conditions and any configuration changes before laying the cable.
Is the cable rodent-proof?
No. The glass yarn construction is described as rodent-resistant. The level of protection needed depends on the route; severe exposure may require a different armor or protective duct.
