Singlemode Reduced Bend Radius Optical Fibre Patch Cords
ADC KRONE’s family of singlemode reduced bend radius optical fibre patch cords has a bend radius that is half that of standard singlemode patch cords without changing attenuation characteristics of the cable. While these cables offer the benefit of tighter bends, a complete system of fibre cable management—defined routing paths, ample access to connectors and cable, complete physical protection, and bend radius protection against macro bends and micro bends—is still required to maintain network reliability, ensure maximum throughput and control operating costs.
ADC KRONE’s singlemode reduced bend radius patch cords have a bend radius of 15 mm, are stringently tested for insertion loss and return loss at the factory and are backwards compatible with standard single mode fibre. ADC KRONE offers ultra physical contact (UPC) polish on the SC, FC, and LC connector styles or angled physical contact (APC) on the LC and SC connector styles. (APC should be used in applications that require better control of return loss) ADC KRONE maintains tight tolerances regarding the rotation of the ferrule to maintain low insertion loss values.
Proper Applications for Reduced Bend Radius Optical Fibre
Singlemode reduced bend radius optical fibre is best suited for environments where little or no bend radius protection is available. It is also ideal for applications where space is an issue.
Space is tight
No fibre management is available
Space is at a premium
Tighter bend radius also offers OEMs the chance to increase the functionality of active equipment by utilizing less chassis space.
A key advantage of reduced bend radius optical fibre is use in high bandwidth applications.
For standard optical fibre, the 1625 nm to 1550 nm wavelengths are the first to go when the cable is wrapped around a mandrel. Preserving these wavelengths around tighter bends offers benefits for OEMs seeking to improve functionality of network equipment or network managers looking for the efficiency of having all wavelengths available on a given optical link.
It is crucial for the health and performance of your network to be aware that reduced bend radius fibre does not, in any case, mean that the fundamentals of proper fibre management are to be ignored. In fact, as this fibre is used in higher density applications, factors such as connector access and cable routing paths become even more crucial. Reduced bend radius optical fibre is just one aspect of a complete strategy for efficient, future-proofed network management.
Bending of singlemode fibre has everyone talking these days. Technicians should be aware that the new breed of reduced bend radius fibres can reduce minimum bend radius requirements significantly, but they can also still become damaged or even broken if mishandled or stressed beyond their limitations. The fibres are designed to reduce the minimum bend radius from the traditional 10 times the outside diameter of the jacketed cable (about 38 mm) to as low as 5 mm with negligible added attenuation.
ADC KRONE uses the term “reduced bend radius,” because this title best describes what the product actually delivers.
