Mini-GBIC slots allow network administrator to enlarge network coveragewith fiber optic network cables. Copper Ethernet cables provide up to 100 meters of distance between a network Switch and its connected network devices. Using available mini GBIC modules, network administrators can extend their physical network reaching further distance. For instance, TEG-MGBS80 provides up to 80 Km (49.7 miles) of single mode fiber optic cabling between two network Switches. TEG-424WS significantly reduces overall cost of ownership by allowing network administrators to extend data network coverage with minimum investment.
