一款应用于FTTH的CATV光接收机的设计

Design of FTTH optical receiver in CATV

在分析国内外FTTH光接收机应用前景的基础上,设计并实现了一款应用于FTTH的CATV光接收机。在低动态接收、高灵敏度和成本方面有较大突破,光功率接收范围达到-8～0dBm,功耗降低到约3W,制造成本降低到300元左右,具有很好的实用价值。

Based on the analysis of the application fore ground of the domestic and, abroad FTTH optical receiver, designed and realized a CATV optical receiver applied for FTTH. There is a bigger breakthrough among the field of low dynamic receiving, high sensitivity and the low cost, the new receiver has a dynamic range of up to -8-0dBm, and power wastage as low as 3W, the producing cost reduced to about RMB 300,owning good practical value.
