Integrated Picor Filter and Hot-Swap
Save Space and Reduce Complexity of a Passive Optical Network
Fiber optics is a technology used to transmit digital signals ― such as television, internet data, and voice ― over longer distances, with less loss, and at higher data rates than other communication systems. A passive optical network (PON) is a fiber optics network architecture that uses a single optical fiber to serve multiple end users.
Our customer is a telecom company that designs and develops PON access equipment.
Their unique technology has led to the development of a new hybrid RF PON system that allows for seamless bridging of traditional telephone service, Ethernet, and video services over a PON system. Fiber systems such as this 10 Gigabit PON offer high volume “last mile” bandwidth allowing users combine voice, video and data with flexibility to support TDM or IP voice, RF or IP video and ultra high speed data. Achieving this requires the ability to combine lots of computing and I/Os into a relatively small space.
The power is -48 V (-42 to -65 V) input, hot-swap enabled, redundant feed, with about 500 W of total system power (less than 200 W per card) It is NEBS (Network Equipment Building System) compliant. That means it meets NEBS technical requirements to ensure network integrity. The QPI-8, which integrates a total hot-swap function with an active EMI filter, aligns with the AdvancedTCA PICMG® requirements for hot insertion and board level conducted noise limitations. Combining the filter with hot-swap helps save valuable board area and simplifies the design.
