Metro 1000 Optical Fiber Switch 16 Port SDH STM-4 PDH Transmission for IP TCP Networks

The OptiX 155/622H provides multiple interface types for SDH services, PDH services, and Ethernet services.

 Interface types provided by the OptiX 155/622H

The OptiX 155/622H provides the following clock sources for synchronization: external clock sources, line clock sources, and tributary clock sources.

When working in locked mode, an OptiX 155/622H can select any of the following clock sources as the reference clock:

• External 2048 kHz or 2048 kbit/s G.703 clock source

• Clock source from an interface on a line board

• Clock source from an interface on a tributary board

• Clock source from a line or tributary interface on an SCB board

The OptiX 155/622H has a capacity of 21.25 Gbit/s higher order full cross-connection or 5 Gbit/s lower order full cross-connection.It can be configured as multiple terminal multiplexers (TMs), add/drop multiplexers (ADMs), or multiple add/drop multiplexers (MADMs).It also supports service grooming and protection among these systems.In this way, the networking capability and the service grooming capability among networks are significantly improved.

The OptiX 155/622H can construct networks flexibly.It supports point-to-point, chain, ring, hub, and mesh networks.

When the OptiX 155/622H functions as the access equipment, it can construct hybrid networks with HW Metro and OSN equipment series.The OptiX 155/622H can also construct hybrid networks with third-party equipment.
