11 Benefit of Free Space Matrix
Insertion Loss (dB) Footprint (Business Card) BD-CDWDM DWDM module Discrete 2.5 dB Free Space X 2 1.2 dB SD-CDWDM 以8CH 產品來說，傳統CWDM Module IL約2.5dB，體積大小約120z80x8mm， 而CCWDM可以將IL降至1.2 dB，減少1.3 dB；體積降至44x25x6mm，體積降低91.4%。 Loss降低1.3 dB，以G.657A1光纖而言，對1550nm光源，傳輸距離可增加6.5km (0.2dB/km); 對1310nm光源，傳輸距離可增加 3.7 ~ 4 km (0.33~0.35 dB/km) 為提供客戶有效提升空間密度，我們力求更小的Size的產品開發，目前已有單一出口更小型化的產品正在試產中。 Mini CCWDM體積為33x18x6，體積再縮小46%，Channel數可達11CH。 目前產品型態幾乎都是11CH以下，針對12Channel以上產品，我們有開發另一個產品型態可達18Channel，體積大小為45x25x6mm。 X 1/8 X 1/4 Remark :Benchmark via 8ch DWDM

IV). Dual Band DWDM Applied I). Min Footprint, Reduce Up to 30% Basic Type Channels: 11 Footprint:¼ Biz Card 我們擁有十幾年微光學 (Micro Optics)產品之開發設計經驗，及五、六年 Free Space WDM Module的開發、量產經驗。 在追求低損耗 (Low Loss)、體積小 (Compact Size)與高性價比 (Performance Cost Ratio)的目標下， 我們已有18Channel的CCWDM，其體積大小只有45x25x6 mm，但品質與可靠度完全不打折扣。 III). Platform Extend to DWDM II). More channels. Add Up, Max 18
