懷化:迎戰冰凍 信號滿格
作者:【】 來源:【湖南郵電報】 瀏覽:【336】發布時間:【2019/3/4】
 

維護人員冒著冰凍進行纖芯測試,尋找故障點。 

      2月23日,陰雨綿綿,低溫冰凍持續,寒氣逼人。高山深處的冰凌強勢襲擊,致使大面積倒樹、倒桿,壓壞、拉斷光纜多處,導致懷化楊村至黃巖段的光纜出現故障,OLT掉線,光衰增大,黃巖片區的寬帶和固話通信出現中斷。

      中國電信懷化分公司維護人員快馬加鞭地驅車在蜿蜒的山路上前進,車子離黃巖越來越近,溫度越來越低,最低氣溫為-6℃。樹梢、樹葉上掛滿了大塊大塊的冰凌,樹兒被壓彎了腰。“嗖嗖嗖”的冷風吹在鼻尖、耳根、手心上,讓人不得不縮緊了脖子。

      懷化分公司維護團隊和裝維外包公司人員先后抵達故障點,大家針對惡劣天氣下的搶修方案進行了短暫的交流。因纖芯有光信號無法測試,無法確定具體光衰點,查修隊伍便兵分兩路,分別沿著楊村和黃巖兩個方向對線路進行巡查。大家在雜草和樹木之間查找故障點,山坡上、樹上的冰凌不時地“啪啪啪”地往下掉,且多處山體滑坡,腳底下發出“咯吱咯吱”的聲音,一不小心就會被跌倒。中午1時30分左右,通過在楊村機房測試光纜障礙點和在黃巖山上找光纜接頭盒進行纖芯測試,確定故障點在黃巖大峽谷牌坊往楊村方向約565米處。

      故障點為下山桿路,因冰雪太厚,且都是懸崖峭壁,人員無法下山,搶修難度很大。本著“保安全,先搶通,后恢復”的原則,搶修隊伍再次分工,一個隊在疊翠蘭亭接頭點進行測試,另一個隊在黃巖山頂接頭點進行跳纖。當問及在現場調度指揮的接入維護中心副主任王學鋒“冷不冷”時,他笑了:“不冷!查修的時候通常都是全神貫注,哪還注意到冷?搞維護工作這么多年,越是雨雪風霜,越是氣候惡劣,越是考驗我們的時候!”

      18時15分,負責搶修調度的接入維護中心副主任王學鋒在易信工作群里發布信息:黃巖光纜故障全部排查完畢,OLT在線,信號滿格上線!
