Product value summary
This BWNFiber source record covers an all-dry stranded loose-tube duct cable in 24F, 48F, 72F, 144F and 288F single-mode configurations. It lists water-blocking yarn in the loose-tube row, water-blocking yarn and tape in the cable core, an FRP central strength member, glass yarn, a black PE outer sheath and count-specific cable dimensions and drum data.
The record does not yet provide a confirmed order code, exact fiber grade, finished-cable tensile/crush/bend limits, temperature range, governing standards or test methods. Select one fiber count and keep its complete construction, dimensions, optical values and drum plan together. Do not combine values from different count columns or from the separate P170 GYF6Y record.
Short answer for buyers
Use this record only as a starting point for a 24F–288F all-dry duct-cable quotation. Before approval, ask BWNFiber to identify the exact model and source revision, confirm the selected count’s table column, and add the mechanical, environmental, installation and test limits required by the route. A fiber count and the words all-dry or duct cable are not enough to release an order.

The source also shows ≤0.25 dB/km at 1550 nm, ≤0.22 dB/km at 1625 nm, ≤18 ps/(nm·km) at 1550 nm and ≤22 ps/(nm·km) at 1625 nm without preserving unambiguous parameter names. These values must remain withheld from publishable copy until engineering identifies each parameter.
Mechanical and environmental status
The source records micro-bending loss for 100 turns at Φ50 mm: ≤0.05 dB at 1310/1550 nm. This is not a finished-cable minimum bend radius and does not establish pulling, installed or service bend limits. The following remain TBC — source required:
- Installation and long-term tensile limits
- Short- and long-term crush limits
- Loaded and unloaded bend radius
- Impact and repeated-bending criteria
- Operating, storage and installation temperatures
- Water-penetration test and acceptance criteria
- Permitted pulling, blowing or jetting method
- Applicable IEC, ICEA, Telcordia, TIA or other project standards

How to select the correct configuration
- Confirm whether the route is duct-only and whether the installation will be pulled, blown or jetted.
- Select the exact fiber grade and count; separate working fibers, restoration capacity and planned reserve.
- Confirm the count-specific tube layout, cable diameter and weight against the corrected controlled drawing.
- Define duct inner diameter, occupancy, route length, bends, pulling points and environmental exposure.
- Add the required tensile, crush, bend, temperature, water-blocking, sheath and electrical constraints.
- Agree on drum length, tolerance, marking, packaging and delivery destination.
- Approve one model/part number, drawing revision, datasheet revision, test criteria and deviation list before production.
Differences from related products
- P170 GYF6Y 48F/144F duct record: overlapping identity with different dimensions and packing data. Do not present it as a separate equivalent until engineering explains the design boundary.
- P085 GYFS all-dry armored duct record: its source table lists corrugated steel tape armor. P169 does not list that armor row. Do not describe the two as interchangeable.
- P175 GYFY 24F/48F duct record: its source structure and packing label differ. A similar count does not prove the same cable design.
- ADSS cable: a self-supporting aerial design with route load engineering; it does not share the same product role as a duct-only record.
- Direct-burial cable: burial suitability requires explicit model evidence; a duct cable must not be relabeled for direct burial.
