信元時延變差
英文
cell delay variation （cdv）-
Because the physical distance between ouns and olts in apon is different from each other, and the transmission distance will undergo dynamic changes as a result of the variation in environmental temperature and the aging of optoelectrical appliances, the differences in the uplink transmission delay will cause an overlay of the uplink time slots of onus, thus leading to the collision of different atm cell flows
由於apon中各onu與olt之間的物理距離各不相同，並且其傳輸距離也會由於環境溫度的變化和光電器件的老化等因素而發生動態的改變，引起上行傳輸時延差異造成各onu的上行時隙重疊，從而導致不同的atm信元流發生碰撞。
