Abstract

PURPOSE:To perform large-capacity transmission among packages by multiplexing and then converting signals, transmitted among package, into optical signals, and thus transferring the signals. CONSTITUTION:An electric signal generated on a package 1 is multiplexed by a multiplexing circuit 2 and then converted into an optical signal by a module 6 which includes an electrooptic converting circuit and a light emitting element. The optical signal is transmitted to an optical fiber 9 through an optical branching device 8 and sent to another package. The optical signal transmitted through an optical fiber 10 is branched by an optical branching device 8 and then converted into an electric signal by a circuit 7 which includes an optoelectric converting circuit and a photodetecting element. Among converted electric signals, only a necessary signal is selected. The selected signal is demultiplexed by a demultiplexing circuit 3 and sent into the package 1. Consequently, an increase in the number of terminals of each electric connector and the complicating of a back wiring board are prevented, and large-capacitance transmission among packages is performed.

Description

DETAILED DESCRIPTION OF THE INVENTION A ζO shield is installed, for example, in the rack of a switching equipment and is used to transmit signals from a multi-machine O package.

Conventionally, a grasshopper wire sonder board (1Wjl) and a rich connector for 1W1 have been included in the ζOS*O package battle.In this case, if the transmission value 4# of the package increases, the number of mushroom neta 10 terminals increases. Yes, but on the package
IWIO/
``The drawback is that it makes the turns more complicated.

This invention provides a good transmission system by multiplexing package transmission signals, converting them into optical IHIK, and then performing signal reception. But O″eh.

According to the invention from ζO, multiple machines transmit O11 between O packages and transmit heat from the package to the O package. Communication ◆ If you are in a 1-9 package, please indicate the contents of the meeting and send it to the 70 Electrical Signal Association Electrical Light Wag.
Mitsunobu 41KII! In exchange, the O-Party Confucian Association branch branch branch of the O-Party Tsuaipa and others were sent to the O-Party Road.

On the other hand, the message of Confucianism on Party Zengro branched off to the Party Branch-Electric Conversion Road.

Converts the 7ot@ number into an electrical signal and sends it within Sodenki 140 as necessary! 9t) Select the electrical signal depending on the content, and multiplex and separate the electrical signal with the multiplex branch. %iI party element, light branch armpit, me4 enemy, party-electrical conversion one route,
A demultiplexing path is arranged in a housing package, and a signal is optically transmitted using an optical path between predetermined O packages. In the tsukage Seki O molly, the package is specified.

Next, refer to Figure ■ for the example of ζO'lk@08 Maro.

14 and light, module 6 for electric-to-optical conversion circuit and ii*doko, optical-to-electrical separation llll5 and power supply; Each package has 10 parts G scissors... is connected to Hikari 7 Aipahai and 1o, and each power supply connector 11 &! - The overflow power supply line 111 has a lot of writing, and on the 1° package, it is multiplexed with II (! I! Telecommunications 4#% If you are sent your own package, you will receive a 4140 internal review.For example, depending on the package sent to you, you may be asked to open your own package, and the printed wire will be sent to you. The large multiplexed signal was transferred to the Juku Party Confucian number by the Gel 6, and was transferred to the Party Aaipa* by the 70th Mitsushin 4 #Welfare Light Branch S), which is the official OA Tsukage. Because it was sent to.

On the other hand, the optical signal being transmitted to Optical 1 Eye 741@ is

Only 1 ml * 1 sample was taken #3. The selected good signals are demultiplexed at the demultiplexer and transmitted to the package. To make you do it.

Hikari Tsuaipa 9 and 10 are connected in a loop via Party branch pattern Is8 to form Wajima. 1, this optical fiber is made of glass T.

Yuki 2II uses an optical waveguide as an optical path to generate tSO.
*Example 20II is shown, and the same waiting time is added to the 4111th minute corresponding to Fig. 1. Package 1 "l-1"・0

As seen above, ζ0%@ must have one multiplexing path and one demultiplexing path on the package! According to the requirements, a signal control memory, an electric-to-optical conversion circuit, a light-absorbing element, a power-to-electrical conversion line, a light-receiving element, an optical splitter, an optical line, etc. are installed. I worked hard to save my life, and the mold on the electrical connector SO terminal increased, IIWIO.
Complicating the O threshold s * LF, if large-capacity transmission between packages can be performed, the above-mentioned party transfer art OI! Akiko Kombatato is h9, and the package has the effect of making Ogamgi look like 1.
