Infineon Expands its BIDI® (Bi-Directional) Optical Component Family with an Optical Triplexer: Triport-BIDI® Offers Additional Interface for Analog Video

Jun 24, 2003 | Technology Media

Munich, June 24, 2003 – Infineon Technologies, a leading provider of communi-cations integrated circuits (ICs) and fiber optic components, presents its new optical triplexer, the Triport-BIDI® at the fibercomm 2003 trade show in Munich (hall B1, booth 450). With the latest enhancement of its popular BIDI® (bi-directional) optical component family Infineon enables telcos and service providers to offer both reliable, high speed digital services and cost effective analog video signal broadcasting in Fiber-to-the-Home (FTTH) and other access network applications.

The new module allows two-way digital communication over a single optical fiber and features an additional receiver for analog video signals (e.g. 80 TV channels). The technology operates with three different wavelengths and eliminates the cost of additional fibers which are normally required for such applications. Single fiber bi-directional communication doubles the capacity of existing networks without adding any new fibers and simplifies fiber management. The Triport-BIDI even transmits both digital services and additional analog video signals through one single fiber.

The Triport-BIDI is based on Infineon’s field proven classic BIDI technology with several 100,000 modules installed worldwide. It is specially designed for BPON (Broadband Passive Optical Network) systems with analog video broadcast signals on a 3rd wavelength. Its second PIN diode receives standard CATV video signals, modulated onto an optical carrier. In addition to the FSAN (Full Service Access Network) standard compliant Triport-BIDI is operating in the 1310/1490/1555 nm wavelength scheme, Infineon also offers customer specific wavelength schemes, e.g. 1310/1310/1555 nm. The module can be offered in several variants which enables the system designer to use it in different system solutions: BPON (Broadband Passive Optical Networks), GPON (Gigabit Passive Optical Networks) as well as other PON systems, HFC (Hybrid Fiber Coax) systems, but also in Point-to-Point networks.

“ Fiber to the Home, Building, Cabinet or Curb applications solve the last mile access problem. Whether in a PON or a Point-to-Point system - the availability of cost- efficient bi-directional optical components is a key success factor” said Uwe Schmidt, Director Wireline Communications Fiber Optics Marketing at Infineon Technologies. “With the BIDI family Infineon offers a complete range of optical diplexers and triplexers specially designed for PON systems. The BIDI and Triport-BIDI components enable its customers to design fully standard compliant ATM PON and Broadband PON systems and are also perfectly suited for the upcoming Gigabit PON and Ether-net PON standards.” Mr. Schmidt added.

The Triport-BIDI modules contain a laser, a PIN diode with an optional pre-amplifier for digital signals and - different from the Standard Classic BIDI - a second PIN-Diode as receiver for the analog video signals. The transmitter supports data rates of up to 1.25 Gbps. The emitter and receivers of the Triport-BIDI are placed in hermetically sealed TO-cans providing high reliability and long operating life. Suitable for short and long haul links of up to 20 km the modules operate in the temperature range of -40 to +85 °C. The metal housing enables good heat transport, excellent EMI performance, and high reliability.


The FSAN-standard compliant Triport-BIDI is currently in volume production. Engi-neering samples of customer specific versions are available on request. All products can be delivered with fiber pigtail and several connector options.
