Abstract: A glass composition well suited for use in optical amplification consists of an erbium-doped borate glass composition comprising at least 30 mole percent of B2O3. This family of glasses provides a wide useful bandwidth (50 nm and greater) for optical amplification around the 1545 nm region. One preferred sub-family of glasses contains equal to or less than 30 mol. percent of SiO2. Another preferred sub-family of glasses contains equal to or less than 5 mol.% of La2O3 and the ratio of B2O3 to ( SIGMA X2O + SIGMA YO) is greater than or equal to 3.5, more preferably 4.5, where X2O represents monovalent metal oxide(s) and YO represents divalent metal oxides.

Abstract: A glass composition suited for use in optical amplification includes a silicate which includes: at least 5o mole percent of SiO2, and at least one group III oxide, which may be selected from the group Al2O3 and B2O3, the ratio (R) of (X2O + YO) to said at least one group III ocide being less than or equal to 1.3, where X2O represents the sum of all alkali metal oxides present and YO represents the sum of all alkaline earth oxides and PbO and Z nO present. Fluorine may be included in the glass compositions. For composition s not including fluorine, it is preferred that the ratio R should be less than or equal to 1.0. The glass compositions are erbium-doped, and may be are co- doped with Yb2O3 and include dispersants such as Y2O3 and/or Gd2O3. This family of glasses possesses a flat gain characteristic in the 1545 nm region .

Abstract: A multichannel fiber optic communication network incorporates multichannel fiber optical amplifiers having different functions but designe d to use substantially identical gain flattening filters. This is achieved by designing the amplifiers to have total insertion losses such that their respective internal gains (internal gain = net gain + total insertion loss) are substantially th e same, most preferably within 1 dB.
