What Should Be Considered When Buying Tight-Buffered Distribution Cables
When selecting the correct tight-buffered distribution cable for indoor or indoor/outdoor installation, the first consideration will be of fiber type. In general, there are three main categories of optical fiber suitable for use. They are single-mode fiber, 50/125?m multimode fiber (OM2, OM3, OM4) and 62.5/125?m multimode fiber (OM1). OM2, OM3 and OM4 are all with 50/125?m core diameter. But they are different in supported bandwidth and transmission distance. In addition, OM3 and OM4 are laser-optimized fibers which are designed for 10G and beyond 10G applications. The following picture shows us the fundamental optical properties of single-mode and multimode fiber types. Which fiber type should be chosen is dependent upon the transmission distance and the protocol being adopted.
