Insertion Loss insertion loss is the loss of signal power resulting from the insertion

Insertion Loss insertion loss is the loss of signal power resulting from the insertion of a device in a transmission line or optical fiber and is usually expressed in d. Bs. Insertion loss is a measure of attenuation but is a more precisely defined term 原先光功率為 PT, 裝置插入後光功率為PR Insertion loss (IL) in d. B IL (d. B)＝ 10 x log(PR / PT) IL(d. B)＝-10 x log(PT/PR) 8

Power Budget source sensor link design Pd. B ＝ Pdbm ＋ Pdb ＋ Pmargin

Power Budget source sensor link design Pd. B ＝ Pdbm ＋ Pdb ＋ Pmargin The optical power budget, in a fiber-optic communication link, refers to the allocation of available optical power (launched into a given fiber by a given source) among various loss-producing mechanisms such as launch coupling loss, fiber attenuation, splice losses, and connector losses, in order to ensure that adequate signal strength (optical power) is available at the receiver 13
