form of optical fiber , so that when there is pressure from outside yang yang excess can change its characteristics. For avoid damping that big then fiber joining must use techniqueand high accuracy. (Thomas, 1995). 7. Optical Fiber Damping Damping atain ruga-ruga andang terjaon the fiber optics caused by (Zanger, 1991, Thomas,1995): • Loss absorption ( absorption loss ), due to by the nature of optical materials which are not perfectly transparent. RuThis absorption is possible formulated as (Samuel, 1988): luptakeLoss ea−= (6) where α = damping coefficient per unit long, 122 2( without)core core ml n ni−= − (7) l = light path length , θ m = anglemaximum acceptance.

This variation gives rise the refractive index which is modeled as objek small scattering. • Loss of flexion ( bending loss ), consisting of 2 namely macrobending and microbe types nding. Macrobending occursdue to the position of the fiber thattoo songybring it upbecome refraction the light came out from the core. Whilemicrobending occurs due to tekmechanical presence or during the withdrawal process kabel. 8. Optical Detector Optical detectors work for testingh signal information optics into signal informationelectrically.

The detectors are must meetrequirements as berikut (Singer, 1991, Thomas, 1995): • has high sensitivity • have a CE response time pat • memiliki noise internal yang small Characteristic pentng others who must filled with stability,accuracy, not sensitiveon temperature change, and the right price. There are two types of optical detectors usedin the communication systemfiber
