PWR power supply board (AC or DC)
Case (including master board)
Equipment configuration type:
Depending upon the application required the H9MO-1641S can be configured as a branch, relay or
terminal multiplexer. In relay mode it can be used in a chain network or self protecting ring mode. In
terminal mode it may be used as a terminal device in a chain network (including point to point). In
terminal mode it can be a home type (H) or terminal type (T). The 3
rd
optic board can be used to extend
the network into a branch mode.
The difference between a terminal device and a relay device is that the terminal device is only
equipped with one OLT board, while a relay device needs two. By adding one OLT board, a terminal
device can be turned into a relay device. This network structure is suitable for phased construction and
extension of networks.
The H9MO-1641S supports Ethernet by adding the optional ETH board.
The AC or DC power supply is customer defined at order.
Board position arrangement:
H9MO-1641S multiplexer is optimized for 19” wide chassis mount, and the positions of various
functional elements are as shown in Figure 3.1. The OLT-A is situated on the mother board and the
optional OLT-B, OLT-C and ETH boards are shown.
