Quick guide from the manual
This document provides technical specifications and handling guidelines for the Corning FREEDM LST loose tube gel-free plenum cable. Installers must strictly adhere to the specified temperature ranges and minimum bend radii to ensure the integrity of the fiber optic network. This cable is designed for indoor/outdoor use and is plenum-rated for building air-handling spaces.
Description
The Corning FREEDM LST is a flame-retardant, loose tube, gel-free cable. It is suitable for interbuilding and intrabuilding backbones in aerial, duct, riser, or plenum applications. The all-dielectric construction eliminates the need for grounding or bonding, and the water-swellable yarn removes the requirement for gel-filling compounds, facilitating cleaner and more efficient cable preparation.
Installation Guidelines
Proper handling is critical to maintaining fiber performance. Observe the following limits during installation:
- Installation Temperature: 0 °C to 60 °C (32 °F to 140 °F).
- Minimum Bend Radius (Installation): 111 mm (4.37 in).
- Minimum Bend Radius (Operation): 74 mm (2.91 in).
- Maximum Tensile Strength (Short-Term): 1350 N (303.49 lbf).
- Maximum Tensile Strength (Long-Term): 400 N (89.92 lbf).
Cable Design
The cable features a 12-fiber count with 50 µm multimode (OM3) fibers. The fibers are color-coded (Blue, Orange, Green, Brown, Slate, White, Red, Black, Yellow, Violet, Rose, Aqua) for quick identification. The outer jacket is flame-retardant and UV-resistant, allowing for direct exposure to sunlight.
Optical Characteristics
The cable is optimized for high-speed data transmission:
- Wavelengths: 850 nm / 1300 nm.
- Fiber Category: OM3.
- Maximum Attenuation: 3.0 dB/km (at 850 nm) / 1.0 dB/km (at 1300 nm).
- Serial 10 Gigabit Ethernet: 300 MHz*km (at 850 nm).
Standards and Safety
This cable meets the requirements of the National Electrical Code (NEC) Article 770 and is OFNP and FT-6 listed. It is compliant with RoHS 2011/65/EU standards regarding hazardous substances.

Practical help
Common problems
Exceeding minimum bend radius
Ensure the cable is not bent tighter than 111 mm during installation or 74 mm during operation to prevent signal loss or fiber damage.
Installation outside temperature limits
Do not install the cable if the ambient temperature is below 0 °C or above 60 °C.
Excessive pulling force
Do not exceed the short-term tensile strength of 1350 N during the pulling process.
Before use
- Verify the part number 012TSP-T4180D20 matches your project requirements.
- Check that the installation environment temperature is between 0 °C and 60 °C.
- Ensure the cable route allows for a minimum bend radius of 111 mm.
- Confirm that the termination equipment is compatible with 250 µm color-coded fibers.
- Inspect the cable jacket for any damage before installation.
Specs in practice
- All-Dielectric
- The cable contains no conductive metal parts, eliminating the need for grounding or bonding.
