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.
