An optical fiber single-mode patch cord is a cable designed to transmit a single ray of light for long-distance and high-bandwidth data applications, typically featuring a yellow jacket and a 9-micron core.
Key Characteristics
Core Size: Single-mode fiber has a very small core diameter, typically 9 μm (microns), surrounded by a 125 μm cladding, which allows for only a single path (mode) for light to travel. This minimizes signal distortion and loss over distance.
Transmission Distance: These patch cords can support data transmission over much longer distances than multimode fiber, ranging from 10 km to over 100 km, making them ideal for telecommunications and campus backbones.
Wavelengths: They operate at specific wavelengths, most commonly 1310 nm and 1550 nm.
Jacket Color: The outer jacket of single-mode patch cords is always yellow
