L-Band Single/ Dual Stage Isolator

L-Band Single/ Dual Stage IsolatorOptical isolators can block back lection and backscattering in the reverse direction at any polarization sate. They have low polarization mode dispersion (PMD). The optical path is epoxy-free,Website:http://www.zgtech-solution.com, thereby enabling high-power applications. They are based on the micro-optics package technology and featured with the best stability and reliabilityThe products are Telcordia GR-1221-CORE qualified.Performance specificationsParameterSingle stage optical isolatorDual stage optical isolatorGradePAPAOperating wavelength (nm)1310 or 1550 or L bandTypical peak ＆value isolation (dB) (23°C)>42>40>52>50Minimum ＆value isolation * (dB) (23°C)>32>30>46>45Insertion loss typical ＆value ** (dB)0.30.40.40.5Insertion loss maximum ＆value *** (dB)<0.5<0.7<0.6<0.8Return loss (In/Out) (dB)>65/60>60/55>65/60>60/55PDL (dB)< 0.05< 0.1< 0.05< 0.1PMD (dB)0.2(0.05 available upon request)Band width (nm)±15±30Operating temperature (°C)-20 ~ + 70Storage temperature (°C)-40 ~ +85Fiber typeCorning SMF-28Fiber length1mDimensions(mm)5.5x30Power handing (mw)300*At 23°C over bandwidth** Does not include connector, splice and fiber-end fresher losses.*** Including PDL, operating wavelength range, -20° C to +70° C.
