The post-amplifier module is directly fed by the pre-amplifier module and outputs the high optical power level required to feed the Passive Optical Network (PON). There are two main types of post- amplifiers, double-wide and single-wide.

The double-wide post-amplifier module is normally used in a temperature controlled Headend or CO environment. The double-wide post-amplifier module is available in a variety of output port counts (8 to 24 ports). These modules are configured with high density LC/APC optical connectors.

The single-wide post-amplifier module is temperature hardened for use in applications having less temperature control than a headend or CO environment. The single-wide post-amplifier modules have 4 output ports at 17, 18.5, and 19.5 dBm per port, and are configured with SC/APC optical connectors.

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.
