Infineon Technologies has expanded its BIDI (Bi-Directional) optical component family with the release of the Triport-BIDI optical triplexer that enables telcos and service providers to offer high speed digital services and cost effective analog video signal broadcasting in Fiber-to-the-Home (FTTH) and other access network applications.

The module allows two-way digital communication over a single optical fiber and features an additional receiver for analog video signals. The technology operates with three different wavelengths and eliminates the cost of additional fibers.

The FSAN (Full Service Access Network) standard compliant product operates in the 1310-, 1490-, 1555nm wavelength scheme and can be offered in several variants such as BPON (Broadband Passive Optical Networks), GPON (Gigabit Passive Optical Networks), as well as other PON systems.

The Triport-BIDI modules contain a laser, a PIN diode with an optional pre-amplifier for digital signals, and a second PIN diode as receiver for the analog video signals. The transmitter supports data rates of up to 1.25Gbps, and the emitter and receivers are placed in hermetically sealed TO-cans providing high reliability and long operating life.

Suitable for short and long haul links of up to 20km, the modules operate in the temperature range of -40C to 850C, and the metal housing enables good heat transport, high EMI performance and high reliability.

All products can be delivered with fiber pigtail and several connector options.
