Description  
VI’s RXM-155 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-3, SDH STM-1 and other 155 Mb/s fiber-  
optic transmission applications that demand superior  
performance. It is available with a multi-mode fiber  
pigtail with either FC/PC,ST or SC connector.

RXM-155 SONET/SDH Receiver Module  
Product Data Sheet  
Functional Overview  
The optical signal is coupled through a short length of  
50.0 µm multimode or single mode 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 155 Mb/s  
fiber-optic NRZ signal to differential PECL data outputs.  
A PECL 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 with -5 Volts or Grounded. All elements are  
integrated into fiber-coupled 1.3” X 0.635” 20 pin DIL  
package. The RXM-155 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.
