2. Mechanical Installation
2.1 FOM16 is a standard 1 RU unit, which can be mounted on 19 or 23-inch rack. It also works as
a desktop unit. The front view and the rear view are shown in Fig.1 and Fig.2, respectively.
2.2 In order to fit for different size of racks, the brackets can be fastened by means of screws to the
two side walls of the case, as shown in Fig. 3.
2.3 After attaching the brackets, FOM16 is ready for installation in the rack. Fasten the brackets to
the side rails of the rack by means of four screws, two on each side.

3. Electrical Installation
3.1 FOM16 can be either AC- or DC-powered. If both AC and DC are fed at the time, The AC
power is selectable internally first and the DC power is used as a back up power source.
3.2 Use the rear left AC power connector to connect to an AC power outlet capable of furnishing a
supply voltage for either 110 or 220 VAC.
3.3 Use the rear right DC power connector to connect to a DC power source capable of furnishing
a supply voltage -48 VDC.
3.4 FOM16 consists of 16 E1 tributaries, i.e. CH1 ~ CH16. Each E1 tributary uses 4 pins, i.e.
Input Tip/Ring and Output Tip/Ring. Each rear DB-25 connector contains a 4-E1-tributary
group, that is, there are 16 pins designated for 4 E1 tributaries and 9 pins for frame ground
(FGND). The pin assignments are shown in the Fig.7 and Fig.8.
3.5 For the unbalance interface, each E1 tributary has two BNC connectors designated TXTIP
(transmit output) and RXTIP (receive input), as shown in Fig.9 and Fig.10.

3.6 FOM16 provides audible and visual alarm contacts that use relays to activate a circuit loop
between each alarm contact point and the common point in case of an alarm. The pin
assignments of the rear female DB-9 connector are shown in Fig.11.

4. Optical Installation
4.1 FC/PC connectors are used for optical interfaces. “IN” and “OUT” are used to indicate the
directions of laser beam input and output. ”O-W” means the optical working pair and “O-P” the
optical protection pair. The working pair of near end must be connected with that of far end and
the same for the protection pair.
4.2 Eye damage may be caused by a broken fiber or by an unterminated connector if the
laser beam is viewed directly or with improper optical instruments.
4.3 When planning the routing of fiber optic cables, avoid sharp bends.
5. Front Panel Indicator
Fig.11 shows the front view of the FOM16, and Table 1 lists the functions of the FOM16
controls, connectors, and indicators, located in the FOM16 front panel. The index numbers in
Table 1 correspond to the item numbers in Fig.13.
