 AOT-AIPHONE 


 The Product Summary
AOT telephone data fiber equipment to use word nothing compression technique and internation the most advanced numeral vidio and the ultrahigh speed optical fiber transmission technique at a high speed total number , multiple telephone , data and etc the at the same time nothing of signal on two rush pith optical fibers of lacks fidelity and the high quality transfer , has economized the user's set capitalized cost greatly , and has raised the photo cable utilization ratio .
The AOT telephone data fiber equipment uses the modularization and the structured design , user can dispose according to nimble selections of concrete circumstances of field or customization , and the at the same time can provide OEM and supply the goods method to user .
The AOT telephone data fiber equipment possesses that capability price is wideer than high dynamic range and the volume is small and uses is convenient and can suit the characteristics such as many kinds of complicated environments etc because of his , and the extensive use at present in the traffic , public security , customhouse and supervision of large-scale factories and mines is in vidio transmission system etc many domains
My corporation has developed out AIPHONE special and has held the machine product to AOT-AIPHONE series light speaking the product circumstances of shorter and can not meet again ordinary audio fiber equipment be dead against loves the peak product transmission range , and this product is suitable the internal to speaking the product of AIPHONE each model , and the end machine set a camera can transmit all the way to speaking the signal , for monomode SC's interface .
The AOT-AIPHONE specially to speaks solely holds machine series word type light to hold the machine , can on one or two optical fibers the audio to speaks the system to need of transfer ALPHONE .
AF-AIPHONE is for the monomode fiber equipment , and has the power supply pilot lamp summation tone frequency state pilot lamp on the front panel .
The person who at present successful applies in the various places in whole nation to speaking the engineering to the audio data transmission system of long distance ALPHONE who is possesses high reliability and high performance price ratio to speaks to LEF , LEM and NEM' Audio and the data control protocol to speaks the system of AOT-AIPHONE plug-to-plug compatibility ALPHONE .


 The roduct characteristic 
◆ It is compatible voluntarily PAL、NTSC、SECAM vidio standard
