Note on LINDEN-SPE-7110-12 Hybrid (-054)
The exact (-054) revision/configuration and LINDEN-SPE-7110-12 specification sheet does not appear to be publicly available. Linden Photonics typically assigns these specification numbers to customer-specific cable designs, so details such as:
- Fiber count
- Conductor count and gauge
- Cable outer diameter
- Tensile rating
- Weight
- Working load
- Minimum bend radius
- Buoyancy specification
are often unique to the customer’s project and available only in the proprietary datasheet.
If you need the exact engineering specifications for LINDEN-SPE-7110-12 Hybrid (-054), the original Linden Photonics specification sheet or procurement documentation would be required.
