Expansion Module of RG-DEMUX Series 24-Port Core Combiner

Used in Simplified Optical Ethernet solution to make distribution nodes passive and provide exclusive Gigabit/10G bandwidth for Fiber-to-The-Room (FTTR)



Highlight Features

  • The expansion module of the 24-port core combiner uses three WDM fibers for transmission, which effectively reduces trunk optical fibers required in buildings.
  • The unique colored optical technology is used to provide exclusive Gigabit/10G bandwidth for indoor use, which meets network requirements.
  • The all-optical network involves only passive devices, exempting ELV rooms from O&M management and making distribution nodes passive completely.
  • The modular expansion module is easy to fix and install.

RG-DEMUX/MUX Series 24-Port Combiner/Transparent Distribution Device

They are applied to enterprise-class all-optical network scenarios. The products innovatively combine the colored optical technology with passive devices using the Ethernet architecture to physically isolate channels of the device. They can be used together with Simplified Optical Ethernet solution 2.X to make distribution nodes passive completely and achieve 1G/10G bandwidth to the room.


Installation Modes

Various installation modes: The product with a height of 1 RU can be installed in a core-side 78C chassis, in a core-side 19 RU rack, or on a wall.

The Ethernet architecture is transformed from three tiers to two tiers, and the building ELV rooms are truly passive and exempt from O&M management

The RG-DEMUX/MUX series combiner/transparent distribution device use the passive network design, replacing distribution switches. The devices from the core side to the access side are directly connected in a point-to-point manner. The controller displays the topology of the entire network, including port usage. This allows you to respond to link failures in a timely manner.

Solution Advantages

Topology Comparison


For example, an office building has 6 floors, with 2 ELV risers and 20 rooms on each floor, and 4 information points in each room.

Exclusive 1G/10G bandwidth to room, ease of link upgrade, no need to replace transparent distribution devices

Exclusive bandwidth

Ease of Bandwidth Expansion


1:1 bandwidth for FTTR, zero optical splitting, and no convergence. The access-side port rate is the same as the core-side port rate, implementing point-to-point transparent transmission.

How to ensure safety when installing an SF series all-optical switch in a telecommunication box?

The switch size is smaller than that of the previous generation. The regulation-compliant open area, excellent space layout, and right-angle power plug ensures security. The innovative shark fin design increases the heat dissipation area and improves heat dissipation efficiency, making the operation safer.

How to simplify O&M for the SF series all-optical switches?

The switch can be used in combination with the INC controller, to implement fast onboarding, plug and play, and no commissioning. The link fault locating function, together with the INC controller, allows you to check the link health status and alarms, improving the troubleshooting efficiency and achieving zero touch replacement. Traffic routes do not need to change, and different switches can be flexibly used for replacement as required.
