Extends the range of equipment with

electrical E3, T3 or HSSI interfaces

In-band management on both local and

remote units

•

Redundancy on fiber optic link and

power supply

Wave Division Multiplexing (WDM)

module for operation over a single-

strand fiber optic link

•

Different clock modes including central

system clock

•

Wide range of modular optical

interfaces

The FOMi-E3 and FOMi-T3 are high speed fiber

optic modems that extend the transmission

range of electrical E3 or T3 over fiber optic

cables:

FOMi-E3 for E3 rates (34.368 Mbps)

FOMi-T3 for T3 rates (44.736 Mbps)

The standalone version of both modems can

optionally support an HSSI DCE interface, which

operates at the same rate as the modem type

into which it is inserted (E3 at 34.368 Mbps and

T3 at 44.736 Mbps). The HSSI option also

supports bit rates of one-half and one-fourth of

the main link rate. This option enables

connection of high speed HSSI routers over

backbones at E3 or T3 rates.

Low cost extension and conversion of

E3/T3 fiber interfaces

The FOMi-E3 and FOMi-T3 can substitute for an

ACE, DXC or Optimux unit at the central office

that works opposite identical devices at the

customer premises, thereby enabling low cost

extension and conversion of E3/T3 fiber

interfaces to standard electrical interfaces. When

replacing an Optimux device at the central

office, the FOMi-E3 or FOMi-T3 enables the use

of one E3/T3 port on the ADM rather than using

many E1/T1 ports.

Wide range of optical interfaces

The optical interface of the FOMi-E3 or FOMi-T3

is modular. The modems support the wide range

of optical modules supported by the AMC-101

and Optimux. These modules include

multimode, single mode, laser, long haul laser,

WDM, and all types of optical connectors. There

is an option to install two optical interfaces for

full redundancy of the optical link. There is also

an option of dual power supplies for additional

redundancy.

FOMi-E3 and FOMi-T3 are available as cards for

the LRS-24 19-inch SNMP-managed rack. The

LRS-24 rack can accommodate up to seven

FOMi-E3 or FOMi-T3 cards, saving cost and

space at the central office.

Management options

RADview, RAD’s SNMP network management

system for modem applications, enables

management of multiple LRS-24 chassis and the

attached remote units. These can be other

FOMi-E3 or FOMi-T3 units or FOMi-E1/T1 and

FOMi-40 units.

Another option for managing a pair of FOMi-E3

or FOMi-T3 modems is with an ASCII terminal

connected to the RS-232 connector on the front

panel of the standalone unit, or on the LRS-24

activated from a remote site using a dial-up

modem connection.

Dry contact alarm relay for activating external alert

devices in case of major or minor alarm is

available in the FOMi on the rear panel of the

standalone modem or on the common logic card

of the LRS-24.
