2. FUNCTIONAL DESCRIPTION
2.1.
PURPOSE
Cellular telephone systems transmit signals in two directions between base
transceiver station (BTS) and mobile stations (MS) within the signal coverage area.
If weak signal transmissions occur within the coverage area because of indoor
applications, topological conditions or distance from the transmitter, extension of the
transmission range can be achieved by means of an optical distribution system.
Such a system contains an optical Master Unit and several Remote Units. The
number of the Remote Units depends on the hardware and software configuration.
The Remote Units are connected to the Master Unit with optical links. The optical
loss must be less than 10 dB inclusive optical couplers or splitters.
The Master Unit is the connection to the base transceiver stations. The configuration
of a Master Unit depends on the number of the Remote Units and the frequency
range.
WDM (Wave Division Multiplex) filters are integrated in the optical modules. For the
UL, a wavelength within 1540 nm – 1562 nm is used. For the DL, a wavelength of
1310 ±20 nm is used. The maximum output power for the UL and DL is 5.7 mW.

THE ION™-M7P/7P/85P/19P (INTELLIGENT OPTICAL NETWORK; MMR)
The ION-M7P/7P/85P/19P is a LTE MIMO, 850 MHz, and1900 MHz CDMA/WCDMA
multi-operator Remote Unit with various Extension Units. It is used in conjunction
with a Master Unit in the ION optical distribution system. This system transports
multiple LTE channels, a 850 MHz, and a 1900 MHz wideband signal simultaneously,
providing a cost-effective solution for distributing capacity from one or more base
stations.
The ION-M7P/7P/85P/19P transports signals on the RF layer in a very inexpensive
manner. This means that multiple operators and multiple technologies are moved
simultaneously from a cluster of base stations to a remote location over the same
fiber.
The ION optical distribution system is a cost-effective coverage solution for dense
urban areas, tunnels, subway, airports, convention centers, high-rise buildings and
other locations where physical structures increase path loss. It has been specifically
designed to reduce zoning problems and to provide homogeneous coverage. The
compact, mechanical design is specifically architected to mount inside of poles or
along side structures in such a way that it has a minimal visual impact.
