光纖網絡傳感器

　　世界依賴于光纖鏈接：從電話聯系世界各地的互聯網骨干網，光纖布線進行兆每天數以百萬計這是增加。根據德國的-海因里希赫茲研究所的數據，在所有經濟衰退中，電信網絡的流量每年都會穩定增長。為了滿足這一需求，提高光纖網絡的容量，更好地利用光纖鏈路來支持現代服務和高分辨率視頻至關重要。

　　這些光纖的基本技術是LED發射機和二極管接收器。發光二極管在波長為1300納米、820納米或650納米的波長上傳輸數據，或者在單模光纖的單一頻率下獲得長距離，或者與多模光纖一起用于具有較高帶寬的短鏈路。光孤子技術已經能夠把一個光脈沖通過4000公里的光纖沒有放大的需要，而同樣的技術已經被用于1 Tbit / s的數據速率。然而，這些還不是商業系統。

　　Increasingly， lower cost plastic fiber is being used with more cost-effective sensors providing the last mile connection for the telecom networks to the home. Developments in plastic fiber transmitter and receiver technology are boosting the data rates such that they will be proof against the increased data needs in the future.

　　While traditional telecom networks operate at standard data rates， most commonly up to 2.4 Gbit/s （or the optical carrier OC-48 standard in the US， and STM-16 in Europe）， now networking technologies are also running at similar speeds. The 10G Ethernet provides links at 10 Gbit/s， comparable to OC-192， while the developments in 40G Ethernet are mirrored by the development of the OC-768 （STM-256） protocol.
