Fiber Type Panda or Bow Tie PM; Operating Temperature -55-+85 °C; Thermal Stability <0.3 dB; Excess Loss <0.5 dB
Due to the significant drop of PER at below freezing temperatures, polarization maintaining (PM) fiber optic couplers usually operate from 0 to +70 °C. Gooch & Housego’s proprietary fused biconical taper (FBT) platform and packaging technology has made it possible to build high performing PM couplers operating reliably from -55°C to +85°C, without significant changes in PER and other optical parameters over such a wide operating temperature range. These types of PM couplers are very suitable for use in many high-reliability systems and modules.
Gooch & Housego’s (G&H) fused polarization maintaining (PM) fiber optic couplers, taps and optical signal splitters offer high polarization extinction ratio (PER) with polarization launch into a single or dual axis (slow axis and fast axis). G&H utilizes a proven, proprietary fused biconical taper (FBT) process to manufacture high-grade PM couplers including single wavelength and wavelength flattened (broadband/wideband) devices.
G&H’s PM components offer high extinction ratio with minimum optical loss. G&H selects PM fiber from different suppliers to accommodate your application-specific operating wavelengths.
