Abstract

PURPOSE: A serial-type optical high frequency repeater for use in mobile communication is provided to reduce a rental fee of an optical core leased line, a rental fee of a base station, and an install fee by using a serial-type. CONSTITUTION: A transmitted optical signal is laterally coupled on 1,2....n number optical directional coupler(forward). The transmitted optical signal is converted in a high frequency on an optical high frequency converter. A channel to service on a band-pass filter is passes. A high frequency high power amplifier amplifies the transmitted optical signal to pass it to a transmitting/receiving separation diplexer. The amplified optical signal is copied on a transmitting/receiving combination antenna. The amplified signal passes a band-pass filter and is converted by a high frequency optical converter to be coupled on an optical directional coupler(backward) .

이동통신을 고주파로 아날로그, 디지털(TDMA, CDMA, GSM, IMTS2000등) 방식으로 써비스 함에 있어서, 여러개의 주파수 밴드를 합성한 후 다시 고주파 광 변환하여 1개 광코아로 여러개 주파수 밴드를 동시에 전송할 수 있도록 직렬 분배하는 방식으로 그 동작 원리는 다음과 같다.In the mobile communication service with high frequency analog and digital (TDMA, CDMA, GSM, IMTS2000, etc.) method, after combining several frequency bands, high frequency optical conversion is performed so that several frequency bands can be simultaneously transmitted by one optical core. The principle of operation in the manner of serial distribution is as follows.

도 1에 마이크로 비티에스 FA순방향(송신)입력(F1, F2‥‥Fn) 단자에 입력되는 종합 기지국 이동통신 고주파 밴드들을 각각 대역통과 여파기 및 고주파 증폭기(I1, I2‥‥In)로 증폭후 고주파 합성기(2)에서 합성 후 고주파 광변환기(3)에서 광으로 변환하여 여러채널을 동시에 전송한다.In FIG. 1, the general base station mobile communication high frequency bands inputted to the micro VTS F A forward (transmission) inputs F 1 , F 2 ... F n are respectively passed through a band pass filter and a high frequency amplifier I 1 , I 2. After amplification with I n ), the high frequency synthesizer 2 synthesizes the light and converts the light to the high frequency optical converter 3 to transmit several channels simultaneously.

전송된 광신호(순방향)는 첫 번째 광방향성 결합기(41)에서 측면 결합 출력하여 첫번쩨 광고주파 중계기(가)에서 중계 송신하고 계속 두 번째 광고주파 중계기(나)를 거쳐 다음 광고주파 중계기 n쪽으로 전송한다.The transmitted optical signal (forward) is side-coupled and output from the first optical directional coupler (4 1 ) and relayed by the first advertiser repeater (A), and then continues through the second advertiser repeater (B), and then the next advertiser repeater n To the end.

광방향성 결합기(순방향)(41)에서 출력한 광신호는 광고주파 변환기(51)에서 고주파로 변환하고 대역통과 여파기(61)를 통과 후 고주파 고출력 증폭기(71)에서 증폭하여 송신, 수신 분리 다이플렉서(81)를 거친 후 송신, 수신 겸용 안테나(91)에서 복사(순방향)하여 가입자 단말기(H1)에서 수신하게 된다. 또 가입자 단말기(H1)에서 응답 송신(역방향) 고주파는 송신, 수신 겸용 안테나(91)에서 재수신하고 송신, 수신 분리 다이플렉서(81)를 거쳐 송신 신호와 분리 출력한 후 저잡음 증폭기(1O1)에서 증폭 후 대역통과 여파기(111)을 통과 후 고주파 광변환기(121)에서 광으로 변환하여 광방향성 결합기(역방향)(131)에 결합하여 마스터 유니트(M)쪽으로 역방향 전송한다.The optical signal output from the optical directional coupler (forward) 4 1 is converted into high frequency by the non-frequency transducer 5 1 , and then amplified and transmitted by the high frequency high power amplifier 7 1 after passing through the band pass filter 6 1 . After passing through the reception separation diplexer 8 1 , the transmission and reception antenna 9 1 is radiated (forward) and received at the subscriber station H 1 . In the subscriber station H 1 , the response transmission (reverse) high frequency signal is re-received by the transmitting / receiving antenna 9 1 , and is separately outputted from the transmission signal through the transmitting and receiving separation diplexer 8 1 . (1O: 1) to to in converting a band-pass filter (11 1) was amplified with the light in the high-frequency optical converter (12 1) was passed through binding to an optical directional coupler (reverse) (13: 1) uplink transmission towards the master unit (M) do.

이 전송된 역방향 신호는 광고주파 변환기(14)에서 고주파로 변환되고 이 고주파는 다시 고주파 분배기(15)에서 1, 2‥‥n 개 분배되어 대역통과 여파 및 증폭되어 기지국 수신기(R1)에 보내져서 단말기와 통신 가능하게 된다.The transmitted reverse signal is converted into a high frequency in the high frequency wave converter 14, and this high frequency is again distributed in the high frequency divider 15, and then band-pass filtered and amplified and sent to the base station receiver R 1 . And communication with the terminal is achieved.

이와 같은 방식으로 나‥‥n 번째 광 고주파 중계기도 첫 번째와 같은 방식으로 동일 순방향 광코아(18), 역방향 광코아(18')로 송신, 수신하여 여러개 기지국 F1R1, F2R2‥‥FnRn(동일 기계실 배치가 가능함)와 동시 통신이 가능하게 된다.In this manner, the n th optical high-frequency repeater also transmits and receives the same forward optical core (18) and reverse optical core (18 ') in the same manner as the first, and then receives several base stations F 1 R 1 and F 2 R 2. Simultaneous communication with F n R n (same machine room layout possible) is possible.

종래의 방식은 F1R1, F2R2‥‥FnRn기지국에 연결된 각각의 광코아를 병렬로 사용하고 기지국을 여러장소에 설치함으로써 많은 전용회선 사용료와 많은 기지국 임대 사용료를 지불해야 하는 폐단이 있었다.In the conventional method, each optical core connected to the F 1 R 1 , F 2 R 2 ‥‥ F n R n base station is used in parallel and the base stations are installed in several places to pay a large leased line fee and a large base station rental fee. There was a dismissal.

위와 같이 본 발명은 직렬형으로 사용함으로써 광코아 전용회선 사용료와 기지국 임대사용료, 설치료를 대폭 줄이는 방식을 채택하였다.As described above, the present invention adopts a method of significantly reducing the optical core dedicated line usage fee, base station rental fee, and installation fee by using the serial type.
