Dual-Link Failure Resiliency Through Backup Link Mutual Exclusion

Abstract
Networks employ page link protection to achieve fast recovery. While the first page link failure can be protected using page link protection, there are several alternatives for protecting against the second failure. This paper formally classifies the approaches to dual-link failure resiliency. One of the strategies to recover from dual-link failures is to employ page link protection for the two failed links independently, which requires that two links may not use ....etc

Music Transmission and Reception with high S/N Ratio using Fiber Optic Communication.
fiber optic cable using RS232 communication. On transmitter side, a keypad is interfaced to enter the data. On the receiver side, 16 X 2 LCD is used to display the data. Fiber optics transmission of digitized messages or information by light pulses along hair-thin glass fibers. Each fiber is surrounded by a cladding having a high index of refractance so that the light is internally reflected and travels the length of the fiber without escaping. Cables of opti ....etc

Why fiber?
Speed- operates at high speed upto gigabits
Bandwidth- large carrying capacity
Resistance- to EM noise
Provide electrical isolation
Distance- Signals can be transmitted further without need of repeaters
Maintenance cost- less
Requirements of digital fiber link
No. of digital signal 8
No. of fiber cable 1
Signal frequency- 0-20KHz
I/p-O/p voltage level- 0 & 24 V for (0 & 1 digital logic)
Transmission Range- 300m
Here, we have selected HFBR-1521 transmitter and HFBR-2521 receiver. Spec ....etc
