Aynı rafta fiber OM2, 50/125 MM, LC / LC ile bağlanması gereken birkaç anahtar var (referans için eklenen 2 ek örnek 10GbE ve OM3'tür).
Bir Verizon teknolojisi bana lazer çok güçlü olduğu ve optikleri yakacağı için zayıflatıcı eklemesi gerektiğini söyledi.
Hiç duymadım, bu db seviyelerinde en iyi uygulamalar var mı?

-5 dBm kabul edilebilir mi? Varsayılan 'ALARM'lar' -1 ile -16 arasındadır, ancak -10 dBm'yi hedeflemeli ve 5db zayıflatıcılara para harcamalı mıyım?
