12. Cables Fiber Optic Cable bracNet uses the optical fiber services of GP. Submarine Cables Grameen Phone (GP) is connected to the information super highway via the submarine cable. HSSI Cable They work as an interconnection between networks (e.g. LAN, Wan, etc.) or network devices (e.g. routers, switches, etc).

13. Performance bracNet measures its performance by some performance improving teams which include WiMAX team and Optical Fiber team. bracNet also have a bandwidth Manager that have full-featured traffic management tool that gives control of its network traffic, increasing the efficiency of network and reducing overall bandwidth requirements.

14. Reliability The WiMAX team ensures the physical connectivity. Optical Fiber team also does the same thing but it configures through NOC (Network Operating Centre). The basic bandwidths of the users are controlled by bracNet. bracNet implements key through bandwidth manager
