Problems solved by technology

[0012] Compensation methods for preventing gain and bandwidth reduction have been provided, and these methods are mainly implemented in ICs (Integrated Circuits), but implementation in ICs causes problems in adjusting the reflection characteristics of optoelectronic elements integrated therein
[0013] Also, since the RF (Radio Frequency) system uses a feedback circuit using both capacitance and inductance to form a compensation circuit, the compensation circuit becomes complicated

Abstract

PURPOSE: A high-speed photoelectric module compensated with induction is provided to insert an inductor, and to compensate for a parasite capacitance component, thereby simply expanding a frequency bandwidth of the photoelectric module without redesigning a TIA(Transimpedance Amplifier) and a photo diode. CONSTITUTION: A PD(Photo Diode)(1) receives an optical signal, and converts the received optical signal into an electric signal. A compensating inductor(2) offsets a capacitance component of a parasite capacitor. A TIA(3) amplifies the converted electric signal. A DC(Direct Current) cut-off capacitor(4) cuts off DC components, that is, noises included in the electric signal outputted from the TIA(3).

Description

[0001] Cross References to Related Applications [0002] This application is based on Korean Patent Application No. 2002-78747 filed with the Korean Intellectual Property Office on December 11, 2002, the contents of which are incorporated herein by reference. technical field [0003] The invention relates to a high-speed photoelectric module. Background technique [0004] Recently, as the demand for high-quality communication services has surged, studies on the transmission speed of optical communication systems have also increased. As early as the early 1990s, a 2.5Gbps transmission system was developed, and in 1998, a 10Gbps system also entered the commercial stage. It is possible to build a 40 to 100Gbps system for an ultra-high-speed broadband communication network according to the wavelength division multiplexing method by utilizing an optical module with a transmission speed of 2.5Gbps, however, it requires the use of optical components and electronic modules with a t...
