HGPMJ Hermetically Sealable PM Patch Cables

Polarization Maintaining Patchcords. Metal Solder; Polarization Extinction Ratio >20, >25, >30 dB; Helium Leak Rate<10-8 ATM-cc/s; Operating Temperature -40 to +85 °C; Max. Installation Temperature +210 °C OZ Optics’ HPMJ series of hermetically sealable polarization maintaining (PM) patchcords with metal solder are designed for today's stringent requirements for component packaging. Utilizing metalized fiber and a proprietary sealing process, these patchcords feature a rugged hermetic feedthrough that can be soldered into an opto-electronic package using standard tin/lead solders. The hermetic seal tube is gold plated to promote good on-site sealing and corrosion resistance. These assemblies are capable of easily creating a seal that meets industry hermeticity requirements. PM fibers offer a means to control polarization of optical signals throughout the system, thus controlling Polarization Dependant Losses (PDL) and Polarization Mode Dispersion (PMD). This control is crucial in developing high speed, 40 Gbs, 100 Gbs coherent detection systems. In general, OZ Optics uses polarization maintaining fibers based on the PANDA fiber structure when building polarization maintaining components and patchcords. However OZ Optics can construct devices using other PM fiber structures. If necessary, OZ Optics is willing to use customer supplied fibers to build devices.
