　　高精度IRIG-B光纖收發(fā)器
　　發(fā)送延遲補償解調碼達4公里以上的sel-3405高精度IRIG-B光纖收發(fā)器光纖電纜,。
　　預算零售
　　特色應用
　　在光纖布線的IRIG-B碼轉換解調IRIG-B從時鐘′的DB-9或BNC端口（使用適配器電纜）成纖維sel-3405t,，sel-3405r接受IRIG-B通過光纖端口和輸出到DB-9或BNC端口（使用適配器電纜）。
　　B從遠程時鐘把時間從遠程衛(wèi)星時鐘進入控制室,。這是特別有用的,，在安裝天線的位置是不可行的,，因為一個明確的看法的天空是不可用。把你的天線和時鐘,，它可以得到一個好的衛(wèi)星信號,，并發(fā)送小于200 ns的精確解調碼到使用sel-3405需要。
　　IRIG-B碼的變電站的院子里送的高精度解調裝置在變電站的IRIG-B碼同步,，IEC 61850-9-2采樣值,，或其他高精度授時應用。配置三sel-3405r接收器在一圈送< 1?的IRIG-B碼到多個設備,。
　　適配器電纜
　　這是任何sel-3405 SEL時鐘兼容,。使用sel-c940 DB-9雙插頭電纜將設備連接到一個sel-3400 IRIG-B碼分配模塊。使用一個BNC連接到sel-3400和權力的sel-3405另提供時間,。使用sel-c942 DB-9 BNC公鍍錫銅線電纜電力設備使用sel-9321電源,。使用BNC連接到輸入結束時間裝置或從時鐘接收時間，并使用鍍錫電源線

　　FEATURED APPLICATIONS
　　IRIG-B Over Fiber-Optic Cabling—Convert demodulated IRIG-B from a clock′s DB-9 or BNC port (using adapter cable) into fiber using the SEL-3405T. The SEL-3405R accepts IRIG-B via its fiber ports and outputs it to a DB-9 or BNC port (using adapter cable).
　　IRIG-B From a Remote Clock—Bring time from a remote salite clock into the control house. This is especially useful in locations where installing an antenna is not feasible because a clear view of the sky is not available. Place your antenna and clock where it can get a good salite signal, and send <200 ns accurate demodulated IRIG-B to where it is needed using the SEL-3405.
　　IRIG-B to the Substation Yard—Send high-accuracy, demodulated IRIG-B to devices in the substation yard for synchrophasors, IEC 61850-9-2 sampled values, or other high-accuracy timing applications. Configure up to three SEL-3405R Receivers in a ring to send < 1 ?s IRIG-B to multiple devices.
　　ADAPTER CABLES
　　The SEL-3405 is compatible with any SEL clock. Use the SEL-C940 DB-9 to Dual BNC Male Cable to connect the device to an SEL-3400 IRIG-B Distribution Module. Use one BNC connection to provide time to the SEL-3400 and the other to power the SEL-3405. Use the SEL-C942 DB-9 to BNC Male to Tinned Wires Cable to power the device using an SEL-9321 Power Supply. Use the BNC connection to input time to the end device or to receive time from a clock, and use the tinned wires for power.
