Cisco Prisma Ii Hd,ln,rxr,sa

The Cisco Prisma II optical network is an advanced transmission system designed to optimize network architectures and increase reliability, scalability, and cost-effectiveness. The Prisma II High Density Dual Reverse Optical Receiver (HD-RXR) modules are available in the half-height High Density form factor.The HD-RXR modules contain two independent reverse optical receivers and two RF output ports. A single HD-RXR module occupies one slot in a Prisma II XD chassis. Two such modules can be vertically stacked in an associated Prisma II Host Module that occupies a single-wide slot in the Prisma II standard chassis. Up to 26 HD-RXR modules can operate in a standard 6RU chassis, while up to 16 HD-RXR modules can operate in the Prisma II XD chassis.The ability to mix high density receivers with other Prisma II modules in the same chassis greatly enhances the flexibility of the platform. HD-RXR modules are available in three versions: Standard Gain, High Gain, and Low Noise.
