Santec Launches PON Filter

KOMAKI, Japan -- Santec are pleased to announce the release of a 1310/1490/1550nm triplexer filter for Passive Optical Networks (PON). PON technology is rapidly becoming the solution of choice for FTTH and similar access networks.

Santec's Super-PON Triplexer Filter has been developed specifically for this application and has isolation values in excess of current standards to enable high quality transmission of analogue video on the 1550nm wavelength channel. The filter incorporates a number of technological advances which enables low cost manufacture of both the ONU and OLT modules. Firstly, proprietary filter coatings, which Santec refers to as Grand-Ex, are used which achieve a reflection isolation of >35dB. This eliminates the need for a second filter to increase the isolation.

Secondly, ultra-low reflectance, <0.01%, AR coatings eliminate the requirement for a substrate with a tapered edge. This reduces manufacturing cost of the filter chip and simplifies alignment of the optical modules.

Santec can supply filter chips for integration with lasers and photodetectors in triplexer transceivers, or can supply pigtailed modules for direct implementation in ONU and OLT modules.
