Both optical patch cord and optical transceiver have single mode / multimode. If the collocation is usually wrong when using, it will lead to the parameter error of the optical modules. How exactly to match the use of patch cord and optical transceiver?
What are the variations between single mode and multimode optical transceiver?
The wavelength of single mode modules are 1310nm and 1550nm, transmission distance can up to 160KM. A metropolitan area network that is commonly used for long distance and relatively high transmission rates.
The wavelength of single mode modules is 850nm, transmission distance can only up to 2KM. Used in short-distance transmissions.
What are the distinctions between single mode and multimode optical fiber?
Single mode fiber transmission has high frequency bandwidth, long transmission distance and high cost; The core diameter is definitely small, usually is 9/125um Singlemode patch cords ; Dispersion can be small, allowing only one mode to transmit. Single mode optical fiber can transmit optical fiber directly to the center, generally useful for long distance data transmission.
Multimode fiber has low transmission speed and short distance, but its cost is relatively low; With a larger diameter, usually is certainly 50 or 62.5 um; The dispersion is normally large, hundreds of mode transmissions are allowed. Multimode fibers are often used in short distance data transmission.
Optical modules and patch cords must be properly matched for normal use.
If the optical fiber in the info center are all multimode, then you'd better use multimode optical modules, single mode and multimode can't be mixed. Because the core diameter of single-mode fiber and multimode fiber is very different, it will cause too much loss when matching.Know more:www.oemfibers.com
