The OLSON TECHNOLOGY, INC. MetroNode Model OTMN-II
is a high performance, four output CATV optical node, offering
the capability of greater than +50dBmV output levels. This
node benefits the system operator by extending overall path
length, maximizing equipment usage and reducing the number
of network elements. Full RF output can be maintained with an
optical input as low as -4dBm. With system performance to
870MHz (or optional 1GHz), the MetroNode OTMN-II provides
the ideal platform for support of the evolving technologies and
services in today’s advanced HFC and PON networks.
MetroNode OTMN-II offers protection configurations which are
ideal for critical analog and digital transmission, telephony and
data services. Utilizing extensive modular design with easy in­field replacement, the MetroNode OTMN-II can meet any
advanced broadband network requirement.
