We have fabricated an erbium-doped phosphate glass fiber with a silica cladding and used 5cm length of it to form an optical amplifier. A bulk erbium phosphate glass called MM2 was used as a core glass in a silica cladding tube to prepare a preform using “core-suction” technique. This MM2 glass preform was drawn to a fiber and the resultant fiber was of good optical quality, free from air bubbles...
This paper proposes CDC ROADM architecture compatible with emerging DWDM super-channel technology. A real world network model is used to quantify that this architecture requires fewer network components leading to less capital and operational costs.
