Description
VI’s RXM-750 is an integrated fiber-optic receiver
module. It is powered by a single +5V power supply and
is housed in a 20 PiN DIL package. It is ideally suited
for SONET OC-1, 3, 12 and other 45Mb/s to 750Mb/s
fiber-optic transmission applications that demand
superior performance. It is available with multi-mode
fiber pigtail with either a ST or LC connector.

RXM-750 SONET/SDH Receiver Module
Product Data Sheet
Functional Overview
The optical signal is coupled through a 62.5 µm
multimode optical fiber to a hermetic module which
encases an InGaAs PiN-photodiode and preamplifier.
The PiN-photodiode converts the optical signal to an
electrical current. The signal is then converted to a
voltage and amplified by a low noise transimpedance
amplifier.
This highly integrated module converts a 45Mb/s to 750
Mb/s fiber-optic NRZ signal to differential PECL data
outputs. A CMOS flag alerts the user to a loss of signal
condition when the optical input falls below an
acceptable level.
A single +5 Volt supply provides bias for the module’s
preamplifier, and Quantizer. The photodiode may be
biased to +5 Volts. All elements are integrated into
fiber-coupled 1.3” X 0.635” 20 pin DIL package. The
RXM-750 footprint and pinout are industry common for
ease of integration.
Further gain is provided by the quantizer, which also
provides a Flag output when the optical signal falls
below an acceptable level.

Absolute Maximum Ratings
Absolute maximum ratings are provided here as
worst case and short duration exposure conditions
only. Exposure to conditions more severe than the
Absolute Maximum Ratings may result in permanent
damage. Exposure to conditions at the Absolute
Maximum Ratings for extended periods may also
adversely affect device performance or reliability.
Functional operation of the device is not implied at
these conditions.
