Commonly used in building fiber optic cabling system, there are three types: 62.5/125 m multimode fiber, 50/125 m multimode fiber, and single-mode fiber.
With SYSTIMAXSCS development of a new 50/125 m, for low-cost 850nm laser-optimized fiber optic cabling systems for global applications, and standards have also joined the series.
Required to meet these basic types of fiber must meet minimum performance levels required, the broad bandwidth and attenuation that must meet the terms of the performance requirements. The application of standards for their transmitter and receiver define the minimum performance standards, and to meet the standards of the worst combination of circumstances to provide a solid specification.
Into account these issues, users, consultants and suppliers installers should ask the key characteristics of such fiber-optic security and support that. Support the validation of these may include several different "proof." For multimode fiber, there is a "proof" to "overflowing bandwidth" or "high-limit mode of loading (RML) Bandwidth." Another "proof" for "they have to test multiple products." All these prove that are defective.
Multimode fiber is a multi-path transmission medium. It depends on the bandwidth of which path (or mode) signals. The initial path from the transmitter to enable the conditions to be. The bandwidth of the laser transmitter overflow (usually used for 155Mb / s or more applications) in bearing capacity of smaller minimum bandwidth performance, as the opening of these conditions far from the transmitter, and usually no overflow condition. RML bandwidth encountered the same problem. Experiments on the development RML conclusions apply only to 62.5 m fiber, only if and to meet the specific conditions of the transmitter is enabled only when used together effectively.
No one application is enabled by these conditions, studies have shown that the transmitter does not satisfy the conditions to enable widespread. Finally, the reliance on a small number of optical fiber test and come to the conclusion, that the manufacturer can not know how to select high quality performance.
, Of course, there are some manufacturers to extend the range of support and use of fiber optic 1300nm multimode transceiver link, such as 1000BASE-LX. Because there are not any standard provisions enabled 1300nm source conditions, the production of such transmitter may form a variety of methods of operation of various multi-mode fiber.
Therefore, these claims must indicate the spontaneous opening of all possible, or must rely on external conditions?? For example, by opening expensive mode conditioning patch cord compensation strict control mode is enabled. This 850nm laser optimized multimode fiber direct contrast, multi-mode fiber transmission characteristics with DMD control, consistent with the definition of spontaneous opening of 850nm application conditions.
But the multi-mode fiber in the 1300nm window, long-distance solution gives rise to another problem. Why do users need to install a new 1300nm multimode fiber to support enhanced 1000BASE-LX, and 1000BASE-LX transceiver was originally produced for the single-mode fiber.
People alternative solutions for multi-mode single-mode because it is multi-mode solutions, lower cost, rather than lower the price of fiber, in fact, multi-mode 850nm Electronic Instrument Much lower cost. This is why use optimized multimode fiber for transmission in the 850nm window, meaning.
