Reliability & Qualification Report for MEMS Based Variable Optical Attenuators W } ] ( } u } v Telcordia GR-1209-CORE "Generic Requirements for Fiber Optic Branching Components with GR-468-CORE. Optical parameter measurements are made at the before and after the Electro-Optic Components comply with Telcordia GR-468-CORE specs. This NEBS Network Equipment-Building System document presents the Telcordia view of proposed generic reliability assurance practices for most optoelectronic devices used in telecommunications equipment. GR-1221-Core states that the ultimate qualification of an epoxy type adhesive is the responsibility of the fabricator of the optical system. Qualification depends upon maintaining optical integrity throughout an appropriate test regimen. Accelerated environmental tests are described in 6.2.1 - 6.2.10. It recommends Woodward Academy's Rising 4 th Grade Math Packet Name:_____ Please put the pages in order & staple before turning in to your Math teacher on the first Friday after the beginning of school. You will be given an assessment over the contents of this packet on a date to be announced by your Math teacher. For the best answers, search on this site shorturl.im/ax9rZ This is my job, so I can give a good answer, but please note, there are a lot of variables, depending on how many doctors/hospitals you have been to and how many years it goes back.--I would have to know more about that to give you a more specific answer. Telcordia GR-487-CORE. The requirements of telcordia GR-487-CORE are intended to provide a suitable environment for telecommunication companies' electronic and passive equipment that is housed in above ground cabinets or enclosures, typically pad- or pole-mounted, in an Outside Plant (OSP) environment. zbgb.org Shock tests occur typically at 500 g for 1 ms, and vibration tests are performed from 20 Hz to 2000 Hz based on the Telcordia GR-468-CORE standard. Finisar's engineers often must design and build their own test equipment to keep pace with marketplace demand for 100-Gbps optical transmission speeds. ???? > ???? > ???? > ??????? > Telcordia GR-468-CORE-issue2.pdf Reliability Assurance Requirement for Optoelectronic Devices Component level qual (Laser diode, LED, PD, ) Mechanical, environment and electrical Tests in parallel Integrity tests - harsh test conditions Long duration Sampling Plan Optical electrical functional testing Pass/Fail criteria The GR-468 test qualification includes: 1.1 Scope and Purpose . . . . . . . . .
