- Product Introduction
Fabricated los ntawm fused-biconical-taper thev naus laus zis nrog Panda PM fiber ntau, qhov 2 × 2 PM txuas txuas txhawb nqa ob txoj kev kho qhov muag lub zog sib cais thiab sib txuas ntawm 1064 nm. Nws khaws cia lub xeev polarization nrog siab PER thiab qis tshaj poob. Compact nyob rau hauv-kab pob guarantees ruaj khov kev ua tau zoo nyob rau hauv txawv kub. Zoo tagnrho rau fiber ntau lasers, coherent detection, fiber-optic sensing thiab interferometric ntsuas. Kev cai cais piv, fiber ntau ntev thiab connector hom muaj.

1). Cov specifications yog tsis muaj connector. Rau cov khoom siv nrog cov khoom sib txuas, IL yuav tsum yog 0.3dB (1310 ~ 1550) lossis 0.5dB (980 ~ 1060) lossis 0.8dB (780 ~ 850) siab dua, ER yuav tsum qis dua 2dB.
2). Cov lus qhia tshwj xeeb tau muab rau cov axis qeeb ua haujlwm nkaus xwb, yog tias cov axis ceev lossis ob qho tib si axis ua haujlwm xav tau, IL yuav siab dua 0.3dB.
3). Rau cov cuab yeej ntxiv cov khoom sib txuas, qhov tseem ceeb sib dhos kom qeeb axis yog tias tsis muaj qhov tshwj xeeb
