Product Overview Hong satisfied OASN fiber Automatic Protection Switching System provides an economical and practical solution for secure communications network to protect critical communications fiber route, you can set up a non-blocking, high reliability, secure and flexible, strong anti-disaster capacity optical communication network. Fiber automatic protection switching system by automatically switching stations and network management centers can achieve fiber automatic protection switching, standby power of real-time monitoring of optical fiber and the optical path of the three main functions of the emergency dispatcher. Product Description The models automatic protection device known as fiber, veneer integrated structure, comes with network communication module, standard 1U chassis, protecting a pair of optical fibers, the device parameters can be configured from the network port. Features ◆ fiber occurs when the main block of the device itself can automatically switch to standby fiber ◆ can monitor the status of the primary and secondary fiber line side ◆ Automatic recognition is matt, matt or transmission equipment, automatic locking device side matt ◆ When the light When power changes or exceeds the alarm threshold switching action occurs, the device itself can be issued manually toggle switch on the device can be switched when necessary, through sound and light alarm ◆ buzzer and lights can also be automatically switched back to the network management function ◆ need to set system instruction scheduling switching function ◆ NMS synchronization automatically switched back, and remote parameters configuration function, optical power alarm management function Technical Parameters Index Name 1: 1A-type switching module 1: 1B-type switching module 1 + 1 switching module operating wavelength of 1470nm -1630nm or 1260nm-1660nm 1470nm-1630nm or 1260nm-1660nm 1470nm-1630nm or 1260nm-1660nm receiving end insertion loss <1.2dB <1.2dB <1.8dB insertion loss originator <1.2dB = 66> = 66 return loss (dB) > = 60> = 60> = 60 switching time (ms) <20 = 1000 million times> = 10 million times splitting ratio 97: 397: 397: 3 optical power 0.1dB 0.1dB 0.1dB resolution optical power stability ± 0.2dB ± 0.2dB ± 0.2dB accuracy of optical power ± 0.2dB ± 0.2dB ± 0.2dB average life of> = 30 years> = 30 years> = 30 years of test light emission power> -6 dB optical communication with left 50 % as a test light, no separate test light.
