Name:Optical Transmission Platform

Model:GPT-C

Feature

GPT-C is a new generation optical broadband transmission platform. Compared to other optical broadband transmission platforms, GPT-C enhances module density to save rack space at headend. The 4RU chassis supports up to 16 application modules, excluding the management module.To meet the increasing for higher bandwidth, this platform is designed with working frequency up to 1000MHz, allowing operators to add more profit generating services.Built with ARM microprocessor of the company ATMEL, this platform provides intelligent monitoring and control. Parameters and status could be viewed and configured through either the platform’s operation panel or WEB management.

●High density: The 4RU chassis supports up to 16 application modules.
●Rich bandwidth: Working frequency up to 1000MHz
●High flexibility: Operator could choose different combinations of application modules.
●Redundant power supply: Platform could have 2 power supply units which can be configured to switch automatically.
●Auto recognition function: Any application module could be recognized by the platform automatically.
●Intelligent monitoring and control: User friendly operation panel and WEB management.
