Sekian banyak jenis alarm yang terdapat pada DWDM hiT 7300, mungkin kita hanya tahu beberapa jenis alarm saja dari sekian banyak jenis alarm. Salah satu jenis alarm yang sangat kenal yaitu LOS (Loss of Signal) alarm, alarm inilah yang sering terdengar bahkan ketika terjadi gangguan pada perangkat telekomunikasi DWDM, silahkan hitung saja berapa banyak kita menangani gangguan dan jenis alarm apa yang sering ditangani. Ketika terjadi gangguan pada perangkat telekomunikasi DWDM, coba cek alarm apa yang muncul? karena menurut saya mengetahui jenis alarm itu penting, dengan mengetahui jenis alarm setidaknya kita sudah mengetahui sebab akibat dari problem yang terjadi, sehingga mempermudah dalam action pertama yang mesti dilakukan. Pada perangkat DWDM hiT 7300 dibagi beberapa kategori alarm :
