2.5.Optional Uplink Interface Modules

The modular structure is adopted for 3P@C 4450E. Each 10U chassis has 16 slots, the former two of which are for inserting the SMUB boards. The SMUB provides multiple optional types of uplink interface modules to meet different user networking requirements. The following uplink interface modules are supported:

The following describes the commonly used gigabit interface module (DS-1GLX/DS-1GSX) and the 100M interface module (DS-2FMM/ DS-2FSM/ DS-4TXB/ DS-4ITX) respectively.

2.5.1.1-port Gigabit Long-wave Optical Interface Module (DS-1GLX)

The DS-1GLX module provides 1 gigabit long-wave Ethernet optical interface. The physical interface is a standard SC optical interface whose maximum transmission distance is 10 km. A pair of single- mode fibers is required for it. The fiber length and peer interface type depend on the real situation.
