两台交换机堆叠使用单模万兆光纤，距离两三公里是否可行？

现场两台设备之间的距离大约有两到三公里左右。请问在这种情况下，用单模万兆光纤连接是否可行？有没有光模块类型上的限制，比如必须使用LR模块或者其他？另外，在这么远的距离下做堆叠是否稳定，有没有人有类似的实际部署经验？weibo.com/ttarticle/p/show?id=2309405161528314954068weibo.com/ttarticle/p/show?id=2309405161530412105829weibo.com/ttarticle/p/show?id=2309405161529829097534weibo.com/ttarticle/p/show?id=2309405161529279643737weibo.com/ttarticle/p/show?id=2309405161529392889909weibo.com/ttarticle/p/show?id=2309405161528205902068weibo.com/ttarticle/p/show?id=2309405161530403455081weibo.com/ttarticle/p/show?id=2309405161529938149648weibo.com/ttarticle/p/show?id=2309405161529770377445weibo.com/ttarticle/p/show?id=2309405161529816252600weibo.com/ttarticle/p/show?id=2309405161529229049877weibo.com/ttarticle/p/show?id=2309405161530147864896weibo.com/ttarticle/p/show?id=2309405161529925566976weibo.com/ttarticle/p/show?id=2309405161530135019874weibo.com/ttarticle/p/show?id=2309405161529204146492weibo.com/ttarticle/p/show?id=2309405161530571489668weibo.com/ttarticle/p/show?id=2309405161528629526758weibo.com/ttarticle/p/show?id=2309405161530240139666weibo.com/ttarticle/p/show?id=2309405161528948293710weibo.com/ttarticle/p/show?id=2309405161530567033174weibo.com/ttarticle/p/show?id=2309405161529501679750weibo.com/ttarticle/p/show?id=2309405161530084688186weibo.com/ttarticle/p/show?id=2309405161529531039921weibo.com/ttarticle/p/show?id=2309405161528746967073weibo.com/ttarticle/p/show?id=2309405161528427937870weibo.com/ttarticle/p/show?id=2309405161528897962010weibo.com/ttarticle/p/show?id=2309405161530629947778weibo.com/ttarticle/p/show?id=2309405161528314953783weibo.com/ttarticle/p/show?id=2309405161529887818184weibo.com/ttarticle/p/show?id=2309405161528843436128weibo.com/ttarticle/p/show?id=2309405161528482726047weibo.com/ttarticle/p/show?id=2309405161529665519630weibo.com/ttarticle/p/show?id=2309405161529376112860weibo.com/ttarticle/p/show?id=2309405161529447153792weibo.com/ttarticle/p/show?id=2309405161528788648002weibo.com/ttarticle/p/show?id=2309405161528209834057weibo.com/ttarticle/p/show?id=2309405161530349191219weibo.com/ttarticle/p/show?id=2309405161530252460370weibo.com/ttarticle/p/show?id=2309405161528587321447weibo.com/ttarticle/p/show?id=2309405161528478531842weibo.com/ttarticle/p/show?id=2309405161529317392497weibo.com/ttarticle/p/show?id=2309405161528260427797weibo.com/ttarticle/p/show?id=2309405161530626015325weibo.com/ttarticle/p/show?id=2309405161529153814710weibo.com/ttarticle/p/show?id=2309405161529011208305weibo.com/ttarticle/p/show?id=2309405161528956420278weibo.com/ttarticle/p/show?id=2309405161528679596131weibo.com/ttarticle/p/show?id=2309405161529099288730weibo.com/ttarticle/p/show?id=2309405161529426182370weibo.com/ttarticle/p/show?id=2309405161528146919523weibo.com/ttarticle/p/show?id=2309405161528906350793weibo.com/ttarticle/p/show?id=2309405161529648480468weibo.com/ttarticle/p/show?id=2309405161530202390701weibo.com/ttarticle/p/show?id=2309405161528998363244weibo.com/ttarticle/p/show?id=2309405161530462437854weibo.com/ttarticle/p/show?id=2309405161528537251963weibo.com/ttarticle/p/show?id=2309405161528637653140weibo.com/ttarticle/p/show?id=2309405161530739261714weibo.com/ttarticle/p/show?id=2309405161528155308050weibo.com/ttarticle/p/show?id=2309405161530034356474weibo.com/ttarticle/p/show?id=2309405161529048957228weibo.com/ttarticle/p/show?id=2309405161528688247100weibo.com/ttarticle/p/show?id=2309405161528528863391weibo.com/ttarticle/p/show?id=2309405161529560399876weibo.com/ttarticle/p/show?id=2309405161529719783557weibo.com/ttarticle/p/show?id=2309405161528424005874weibo.com/ttarticle/p/show?id=2309405161530189807809weibo.com/ttarticle/p/show?id=2309405161529593954328weibo.com/ttarticle/p/show?id=2309405161529761726648weibo.com/ttarticle/p/show?id=2309405161528738578520weibo.com/ttarticle/p/show?id=2309405161529333907686weibo.com/ttarticle/p/show?id=2309405161529170591823weibo.com/ttarticle/p/show?id=2309405161529476514006weibo.com/ttarticle/p/show?id=2309405161529707462674weibo.com/ttarticle/p/show?id=2309405161528856019075weibo.com/ttarticle/p/show?id=2309405161528579195056weibo.com/ttarticle/p/show?id=2309405161530353385551weibo.com/ttarticle/p/show?id=2309405161528088461499weibo.com/ttarticle/p/show?id=2309405161530738999367weibo.com/ttarticle/p/show?id=2309405161530043007420weibo.com/ttarticle/p/show?id=2309405161529979830284weibo.com/ttarticle/p/show?id=2309405161529262604320weibo.com/ttarticle/p/show?id=2309405161530520895533weibo.com/ttarticle/p/show?id=2309405161529875234891weibo.com/ttarticle/p/show?id=2309405161528801230945weibo.com/ttarticle/p/show?id=2309405161528373674145weibo.com/ttarticle/p/show?id=2309405161530298859624weibo.com/ttarticle/p/show?id=2309405161530680279358weibo.com/ttarticle/p/show?id=2309405161529115803852weibo.com/ttarticle/p/show?id=2309405161529610994038weibo.com/ttarticle/p/show?id=2309405161528256233561weibo.com/ttarticle/p/show?id=2309405161530457980961weibo.com/ttarticle/p/show?id=2309405161530680541418weibo.com/ttarticle/p/show?id=2309405161528092655847weibo
