The Infineon module for bidirectional optical transmission has been designed for different optical networks structures: In the last few years the structure has changed from point to point planned for Broad band ISDN to a point to multipoint passive optical network (PON) architecture for the optical network in the subscriber loop. Transmitter Electro-Optical Characteristics A transceiver can be realized with discrete elements (Fig. 1). Transmitter and receiver with pigtails are connected with a fiber-coupler (2:1 or 2:2, wavelength independent or WDM). Figure 1. Realization with discrete elements Transmitter Coupler Receiver 2:1 or 2:2 3 dB wavelength independent or wavelength division multiplexing Infineon has realized this transceiver configuration in a compact module called a BIDI® (Fig. 2). This module is especially suitable for separating the opposing signals at the ends of a link. It replaces a discrete solution with a transmitter, receiver and coupler. The basic devices are a laser diode and a photodiode, each in a TO package, plus the filter in the beam path. A lens in the TO laser concentrates the light and enables it to be launched into the single-mode fiber of the module. In the same way the light from the fiber is focused onto the small, light-sensitive area of the photodiode to produce a high photo current. The mirror for coupling out the received signal is arranged in the beam so that the transmitter and receiver are at right angles to each other. This means the greatest possible degree of freedom in the layout of the electric circuit. Symbol Min.

The tracking error TE is the maximum deviation of PF at constant current Imon over a specified temperature range and relative to the reference point: Imon,ref=Imon (T=25°C, PF=0.5 PF, max.). Thus, TE is given by: PF [T c ] TE [ dB ] = 10 x log PF [ 25 o C ] TO-Detector A decisive advantage of the module is its use of standard TO components. These devices, produced in large quantities, are hermetically sealed and tested before they are built in. This makes a very substantial contribution to the excellent reliability of the module. The solid metal package of the module serves the same purpose. It allows the use of modern laser welding techniques for reliable fixing of the different elements and the fiber holder.
