Cold weather has proven troublesome for fiber optic cable performance, often changing the internal geometry of the fiber. Scientists from Bellcore in San Diego have monitored the problem during the past several years, subjecting fiber optic cable to simulated seasonal cycles. Their findings reveal that minor problems have cropped up with equipment that carried light at 1310 nm. However, temperature-induced cable loss is much more severe with dense wavelength division multiplexing (WDM) transmission at 1550 nm. Proposed dense WDM systems set for 1625 nm would be even more susceptible to cold...Read full articleRelated content from Photonics MediaARTICLESEntanglement-Based QKD Could Secure Optical Fiber NetworksA technique to help pairs of light particles smoothly navigate optical fiber networks was performed over 10 km of Singtel’s fiber network.
