ZTE GPON OLT consists of C320, C300, C350, C600, C680, but C350 and C680 are few in the market, so ZTE’s main sales models: C320, C300, C600. ZTE C320 is equivalent to Huawei 5608T, but unlike Huawei MA5608T, C320 has only two main control and power supply slots. The main control board of C320 comes with a DC power interface by default, C320 doesn't have a separate DC power board. If you want C320 AC chassis, you can only be equipped one main control board, then leaving a slot for the AC power board PRAM.

The main control of C320 has the following types: SMXA/1, GE DC; SMXA/3, 10GE DC; SMXA/5, 10GE DC.
