Fiber optic patch cords (or Fiber jumper) is a fiber optic cable with fiber optic connectors installed at one or both ends. Common uses for these optical cable assemblies include fiber optic cable systems and optical to electronic device interconnects.
The single-mode fiber patch cords uses 9/125um optical fiber. Due to the narrow core, it can only transmit one mode of light at 1310nm, 1550nm and WDM wavelengths. Because of this, the single-mode fiber has small dispersion and high bandwidth; The multimode fiber patch cords uses 50/125um or 62.5/125um optical fiber with a wide core, which can transmit multiple modes of light at a given operating wavelength (850nm or 1310nm wavelength), but because of the There are hundreds of modes, and the transmission constant and group rate of each mode are different, resulting in narrow bandwidth, large dispersion and large loss of multimode fiber.
Singlemode and multimode refer to fiber optic cable types. Single-mode fiber optic patch cords are used for long-distance data transmission. Multimode fiber optic patch cords are used for short-distance transmission. At 1G and 10G rates, the transmission distance of single-mode fiber is much longer than that of multi-mode fiber, so why don't all data centers use single-mode fiber? This is because the construction of data centers is mainly based on short-distance transmission. In short-distance transmission applications, multimode fiber has the same performance as single-mode fiber, but the cost is lower. , In today's high-speed network era, the demand for multimode fiber is also great.
The color of the outer sheath of the fiber can quickly distinguish between single-mode fiber and multi-mode fiber. Usually OS1/OS2 single-mode fiber optic patch cords use yellow fiber cables; multimode fiber optic patch cords use orange or water-green fiber cables. Among them, OM1/OM2 multimode fiber adopts orange outer sheath, OM3/OM4 multimode fiber adopts water green outer sheath (for non-military use), and OM5 multimode fiber adopts green outer sheath.
