Prisma D-PON System 
Optical Passives for PON 
Prisma
®
 Optical Passives are designed to support Passive Optical Networks (PON) and 
are used in conjunction with Prisma II transmitters and optical amplifiers. There are two 
product families: couplers/splitters and BWDM filters. 
Prisma Singlemode Multiband Couplers/Splitters provide consistent performance with low insertion 
loss and polarization sensitivity. Available in LGX-compatible or rack mounted modules, these 
couplers/splitters are easy to handle and provide accurate and reliable transmission. 
Prisma BWDM filters for RF video overlay provide the basic building block for combining video and 
data optical signals on a single fiber. The single slot LGX module contains two WDM filters to serve 
independent PONs for high density and design flexibility. 
Prisma BWDM filters for Prisma D-PON are used to multiplex or demultiplex video, data, and RF 
return optical signals on a single fiber. Two versions of this filter are available. The first version 
supports a two-wavelength solution without optical line termination (OLT), and the return optical 
signal can be either 1310 nm or 1610 nm. The second version supports four-wavelength solutions 
with xPON OLT. Both versions are housed in a single LGX module that contains WDM filters to 
serve three independent D-PON for high-density and design flexibility.
