戴尔(Dell)兼容BiDi XFP万兆单纤双向光模块 1330nmTX/1270nmRX 40km

Although the modules are really good and affordable, I always can't stand the slow shipping speed.

First I want to say the salesman's attitude is really bad, the second is that you guys sent me the wrong products. Although they have resent new order to me without charging, I still feel upset.

Website is easy to navigate. Just spent few minutes to place the order. And items arrived quickly and are working well.
