Networking

Since we have discussed connectivity solutions for two duplex optics or two parallel optics in the last post (see previous post:  Connectivity Solutions for Duplex and Parallel Optics ), the connectivity solutions for parallel to duplex optics will be discussed in this article, including 8-fiber to 2-fiber, and 20-fiber to 2-fiber. Parallel to Duplex Direct Connectivity When directly connecting one 8-fiber transceiver to four duplex transceivers, an 8-fiber MTP to duplex LC harness cable is needed. The harness will have four LC duplex connectors and the fibers will be paired in a specific way, assuring the proper polarity is maintained. This solution is suggested only for short distance within a given row or in the same rack/cabinet. Figure 1: 8-fiber to 2-fiber direct connectivity Parallel to Duplex Interconnect This is an 8-fiber to 2-fiber interconnect. The solution in figure 2 allows for patching on both ends of the fiber optic link. The devices used in this link ...
