IOT transmission streams distributed downstream on PON, OAS that configures the standard interface provides a valid entry point for entering the WAN. The pizza box-sized IOT is a low-cost client device that supports broadband voice and data services. In the access network, a specification cannot meet all the needs, which is currently the case for T-1, T-3, and digital user lines. OAN allows enterprise users to enjoy flexible bandwidth of various specifications: 1 Mbps to Mbps and dedicated wave

. But more importantly, if you only perform a loss test at the wavelength of 1300nm, you will miss the most important part of the measurement at the wavelength of 1550nm. When testing a single-mode optical cable, the characteristics of the tested optical cable link at any possible wavelength should be correctly evaluated. If you use LEDs to test single-mode optical fiber cables as discussed above, you can only know the performance of the optical fiber cable link at 1300nm. However, because a s

Future Optical fiber channels According to industry estimates, One day people will switch from unshielded twisted pair wires to optical fibers, but in the future we will see different optical fiber channels than the current OFTD. In the future, the optical fiber channel will adopt a single-mode single-core optical fiber Bidirectional channel. Special Optical Fiber interface

However, such wavelength division multiplexing technology can achieve transmission rates of 224 Gbps (6 channels) and 112 Gbps (3 channels. Although the current technology only supports 3 meters of communication distance, it can already be used in indoor networks. In addition to visible ligh

The basis of the CMYK color mode is not to add light, but to subtract light. in RGB mode, colors are created by adding light. A Monitor (or a TV) is a light source that can create colors. however, a print paper does not emit light; it only absorbs and reflects light. therefore, when you want to convert the monitor color to paper, you must use another color mode CMYK. CMYK is the basis for four-color printing. The four-color processing printing is mainly used to print continuous color images (suc
