GYF6Y 48F and 144F Duct Cable Configuration — Source Record F0695
This working record describes 48-fiber and 144-fiber single-mode duct-cable configurations with stranded PBT loose tubes, an FRP central strength member, water-blocking yarn and tape, glass-yarn reinforcement, ripcords and a black PE outer sheath. The source filenames and packing rows use the designation GYF6Y, but BWNFiber must confirm the public model and part-number identity before release.
Do not combine this record with another GYF6Y table by fiber count alone. The separate F0690 record lists different 144F diameter, weight, sheath thickness and drum data. Select one controlled configuration and keep its drawing, datasheet revision, dimensions, mechanical limits and packing plan together.
Buyer short answer: Send the required fiber count, complete duct route, installation method, duct inside diameter and bends, total and per-drum lengths, quantity, marking, destination and document requirements. BWNFiber should return the applicable part/configuration identity and controlled datasheet before quotation approval.

Blank or merged cells in the source table must not be interpreted as automatically applying to both configurations. BWNFiber Engineering must issue a normalized count-specific table.
Optical values in the working record
These are working fiber/cable values, not an installed-link budget. Splices, connectors, bends, installation stress and workmanship are outside this table.
| Parameter/condition | Working value | Release status |
|---|---|---|
| Attenuation at 1310 nm | ≤ 0.35 dB/km | TBC — controlled source and test basis required |
| Source row at 1550 nm, believed to be attenuation | ≤ 0.22 dB/km | TBC — parameter heading must be confirmed |
| Cable cutoff wavelength | ≤ 1260 nm | TBC |
| Zero-dispersion wavelength | 1300–1324 nm | TBC |

Mechanical, environmental and installation limits
The supplied record does not provide release-ready finished-cable tensile, crush, impact, installation bend, installed bend, installation temperature, operating temperature or storage temperature limits.
The listed 100 turns at Ø60 mm, ≤ 0.05 dB at 1550/1625 nm entry is a microbending-loss test condition. It is not a finished-cable pulling or installed bend-radius limit and must not be presented as one.
Before approving this cable for a duct route, confirm:
- whether placement is by pulling, blowing/jetting or another method;
- duct inside diameter, fill/occupancy rule, bends, access points and route length;
- permitted pulling tension, sidewall pressure or blowing limits;
- installation and installed bend radii for the exact configuration;
- crush, impact, torsion and temperature criteria;
- water-management, UV, fire/smoke, rodent, chemical and electrical requirements where applicable; and
- the inspection/test records required by the project.
ITU-T L.100 describes characteristics, construction, test methods and performance criteria for optical-fibre cables installed by pulling in ducts and tunnels. It is an external requirements reference, not proof that this BWNFiber record complies. Corning’s duct-installation procedure likewise emphasizes the exact cable manufacturer’s tension and bend limitations. The approved BWNFiber datasheet must govern this product.
Working drum plan
| Configuration | Working drum length | Working drum dimensions (D × d × B × b) | Status |
|---|---|---|---|
| GYF6Y 48C | 4,000 m | 1300 × 570 × 825 × 700 mm | TBC — differs from F0690 plan |
| GYF6Y 144C | 4,000 m | 1750 × 790 × 970 × 810 mm | TBC — differs from F0690 plan |
Confirm wooden-drum material, tolerance, net/gross weight, shipping limits, marking, quantity, destination and target schedule separately. do not use for order release MOQ, price, stock, lead time or warranty without current commercial approval.
How to select the correct record
- Identify whether the requirement is 48F or 144F.
- Ask BWNFiber to map the requirement to a unique part/configuration code and source revision.
- Compare the F0695 construction with F0690; do not choose values from both.
- Confirm the route and installation method before approving mechanical limits.
- Approve the count-specific cross-section, dimensions, weight and sheath construction.
- Agree on optical, mechanical, environmental and document acceptance criteria.
- Lock total length, per-drum length, marking, packaging, quantity and destination on the purchase specification.
