M4122 Mobile Solution/Mobile Front-Haul

Overview

DASAN Network Solution M4122 & M4108 is the cutting egde

solution for mobile fronthaul solution and high capacity

transmission system on access network. All modules are flexible, if

operator want to change for signal, configuration and extended

shelf, supplies as easy maintenance.

M4122 is located on the central office, the 5U height(included

filter shelf). On front side is located as 22 slots SIUs and FAN

located and back does power, main control unit, common units.

On top located shelf is the passive CWDM/DWDM filter. M4108 is

located on remote side or curved area, total 3U height(included

filter shelf) except AC/DC convertor. On front is located 8 Slots SIU

and common units slot. But PtoP condition, M4122 to be COT-RT

both, and so on M4108 possible

DASAN Network Solution M4122 & M4108 supports as interface

on client as CPRI(3,4,5,6) and OBSAI(3,4).

And the M4122 & M4108 provides 2 PSU (Power Supply Unit)

slots. And hot-Swapping on the transponder module. This ensures

equipment-level reliability with resilient network architecture.
