The Corning 004K81-31130-24 is a 4-fiber, tight-buffered, multimode (OM1) riser cable designed for indoor use. It is intended for intrabuilding backbone and horizontal installations. The cable features an all-dielectric construction, meaning it does not require grounding or bonding. It is flame-retardant and meets NEC Article 770 and ICEA S-83-596 standards.
Product description
This cable utilizes 900 µm buffered fibers, which are designed for easy and consistent stripping to facilitate termination. The fibers are protected by dielectric strength members and a flame-retardant outer jacket. The cable is orange in color and contains 4 fibers.
Installation and environmental conditions
Proper handling is required to maintain signal integrity. Observe the following temperature ranges:
- Installation: -10 °C to 60 °C (14 °F to 140 °F)
- Operation: -20 °C to 70 °C (-4 °F to 158 °F)
- Storage: -40 °C to 70 °C (-40 °F to 158 °F)
Bend Radius Limits:
- Installation: Minimum 69 mm (2.72 in)
- Operation: Minimum 46 mm (1.81 in)
Mechanical and optical specifications
The cable is designed to withstand specific tensile loads:
- Max. Tensile Strength (Long-Term, ≤12F): 200 N (44.96 lbf)
- Max. Tensile Strength (Short-Term, ≤12F): 660 N (148.37 lbf)
Optical Characteristics:
- Wavelengths: 850 nm / 1300 nm
- Fiber Core Diameter: 62.5 µm
- Maximum Attenuation: 3.4 dB/km / 1.0 dB/km
- 1 Gigabit Ethernet: 300 m / 550 m
- 10 Gigabit Ethernet: 33 m
Standards and compliance
The cable is OFNR and FT-4 listed, making it suitable for riser and general-purpose building applications. It complies with RoHS 2011/65/EU standards. For further information, contact Corning Optical Communications at 4200 Corning Place, Charlotte, NC 28216, USA, or visit www.corning.com/opcomm.

Practical help
Common problems
Exceeding minimum bend radius
Ensure the cable is not bent tighter than 69 mm during installation or 46 mm during operation to prevent signal loss or fiber damage.
Exceeding tensile strength
Do not exceed the specified pulling force (200 N long-term or 660 N short-term for this fiber count) to avoid damaging the internal fibers.
Incorrect installation environment
Ensure the installation temperature is within the -10 °C to 60 °C range. Do not install in environments outside these limits.
Before use
- Verify the part number 004K81-31130-24 matches your project requirements.
- Confirm the installation environment is indoors.
- Ensure the installation temperature is within the -10 °C to 60 °C range.
- Check that the cable path allows for the minimum bend radius of 69 mm.
- Verify that the equipment is compatible with 62.5 µm multimode (OM1) fiber.
Specs in practice
- 62.5 µm MM (OM1)
- Multimode fiber type with a 62.5-micron core diameter, typically used for shorter distance data transmission.
- All-dielectric construction
- Contains no metal, eliminating the need for grounding or bonding during installation.
- Tight-Buffered
- The fiber coating is in direct contact with the buffer, making it easier to strip and terminate.
Images and diagrams
- The cross-section diagram illustrates the cable structure: a flame-retardant outer jacket, dielectric strength members, and 4 tight-buffered fibers.
Model compatibility
- Compatible with standard 62.5 µm multimode (OM1) networking equipment.
- Meets NEC Article 770 and ICEA S-83-596 standards for building installations.
