inside outside

Dexgreen's Inside/Outside cable is designed to withstand harsh outdoor environments, while also being suitable for installation indoors where compliance with fire ratings is essential.

The cable enables quick and efficient connection between the External Fibre Demarcation Box (where it is spliced) and the Internal Terminal equipment within the customers' premises (connected through a factory-tested SC/APC connector). Water-blocking tape between the outer and inner sheathing and the inner sheathing has Kevlar to facilitate direct tacking to the wall with no deterioration in optical performance.

The fibre type is bending insensitive G657B3; therefore, it can go through sharp corners.

The cable is suitable for both indoor and outdoor use. DexGreen has added a UV protective additive to the inner sheathing of its inside/outside cable. This additive now makes the inner sheathing UV resistant and retains the same excellent flame-retardant characteristics – CPR B2ca.

It has excellent mechanical strength, achieved through aramid yarn strength members within the cable, which provides protection when cables are exposed on building surfaces.

The fibre type of the Inside/Outside cable is G657B3 (bending insensitive), which makes the cable suitable for being installed in tight corners while still achieving excellent performance.


  1. Outer sheath - Material: 5mm in diameter LSZH which is easy to strip by hand. UV resistant and water repellent. 
  2. Water blocking tape - Moisture barrier & prevents inner and outer sheathing from sticking together. 
  3. Ripcord - Facilitate easier stripping of outer sheathing. The cable can be peeled by hand. Nominal exposed ripcord length of 240mm. 
  4. Inner sheath -CPR Euroclass B2ca (s1b d1 a2). Material: white 2.9mm in diameter LSZH. Meets all internal cabling building regulations. 
  5. Aramid strength member/ Kevlar - Gives inner sheathing strength for bending within the house and tacking various surfaces. 
  6. Module - 900um 
  7. Fibre - Primary Coating 
  8. Fibre - Cladding 
  9. Fibre - Core: G657.B3 fibre type (bending insensitive). 
  10. Connectorized at one end for quick & more reliable connection with factory tested SC/APC connector.


At DexGreen, we demand quality throughout every area of the business so that we can help people get the best possible service.

fibre hygiene

Fibre optic cable hygiene refers to the practice of maintaining cleanliness and proper handling of fibre optic cables to ensure their optimal performance and longevity. It is critical because even small amounts of dirt or contaminants on the end faces of the fibres can cause significant signal loss, resulting in poor performance or complete failure of communication.

  1. Cleanliness: Dust, dirt, and other contaminants can accumulate on the end faces of the fibres, causing signal loss, attenuation, and other problems. Keeping the fibres clean with the use of specialised cleaning tools is essential to ensuring optimal performance.
  2. Handling: Fibre optic cables are sensitive and can be easily damaged, especially at the connector end. Proper handling techniques, such as avoiding bending the cable at a sharp angle, pulling on the cable, or crushing the connector, are important to ensure the longevity of the cable.
  3. Protection: Fibre optic cables are vulnerable to damage, and it is vital to protect them from physical damage and environmental factors such as moisture, extreme temperature, and UV exposure.
  4. Proper storage: Fibre optic cables should be stored in a dry, cool location and in a manner that will prevent damage to the cable or connectors.

Proper fibre optic cable hygiene can help prevent costly downtime and repairs, ensure optimal performance, and extend the lifespan of fibre optic cables.
