PDH Fibre Optic Multiplexer

The FMUX20 is a 2U high 19" Rack, 20-slot modular Fibre Optic Multiplexer rack. It provides an economic solution in high density fibre multiplexer installations in central offices. All critical components, Power, fans, management module and interface cards are hot swappable, allowing online field replacement. The hot-swappable power modules can be chosen from AC100-240V, DC18-36. or DC 36-72V. The chassis also has a pair of alarm relays and is able to stack up to 10 chassis as one management unit.

20 slot Transponder Platform


  • 2U 19” 20-slot Chassis with AC/DC power redundancy
  • Chassis cascade up to 10 with one IP management
  • Chassis backplane consists of passive components
  • All modules and cards support hot-swap function
  • Two alarm relays

Power Redundancy: All the FMUX20 chassis power supplies are hot swappable and modular, installing two into a chassis provides redundancy should a single power supply fail. A fully loaded chassis can run continuously with only one power module fitted into the chassis.

Intelligent Cooling Fan: To further increase system reliability, the FMUX20 chassis is fitted with two hot swappable fan modules. Both fan modules can be easily removed from the rear of the chassis, without interruption to the operation of the line cards. A fully loaded chassis can run continuously with only one fan module fitted into the chassis.

10 Chassis cascade with one IP management





Chassis Cascade: The FMUX20 features cascadeable management which allows managing a stack (up to 10 chassis) from a single IP address. Chassis are interconnected with standard UTP cables that carry control signals. Each chassis has its own ID, starting with the master chassis ID0 and cascading up to ID9.







Network Management: The FMUX20 chassis provides an NMC (Network Management Controller) card which must be
installed into the first slot of chassis. The NMC card allows a network administrator with the ability to configure and monitor the status of the blades. Management can be achieved locally over RS232, or over the network by Telnet, Web or SNMP.

Protocol Supported: The FMUX20 chassis has been designed as a Fibre Mux Managed platform. This allows network
administrators to deploy the chassis in a wide range of Fibre Mux network. Technologies supported by the chassis included Ethernet Fibre Optic Multiplexer.
