You are building a new network for a small startup financial services company. Security is paramount, so each organization within the company will have its own network segment separated by a router. However, funds are limited, and you have been asked to keep costs to a minimum. You have acquired a used fiber optic switch and want to use it to create a fiber optic backbone that interconnects all of the routers. You purchased several used multimode GBIC modules on ebay that you will install in each router to allow them to connect to the switch. Both the switch and the GBIC modules use MT-RJ connectors. You purchased several used cables from Amazon. However, when they arrived, you noticed that they use LC connectors.
