User manual CISCO PRISMA II XD BROCHURE

[. . . ] One Sheet Prisma II XD High-Density Optical Platform High-density optical platform improves performance, lowers costs and increases reliability. The Prisma IITM XD High Density optical platform provides network operators with unique features that enable the deployment of a carrier-class network. [. . . ] It can house 16 modular optical transmitters or receivers in a 3RU chassis for considerable density advantages. Cisco's solution results in: · Superior Headend/Hub rack space efficiency · Increased network reliability · Lower maintenance costs · Higher RF output levels · Elimination of most reverse headend driver amplifiers · Improved performance, low costs, and increased reliability One Sheet Prisma II XD Chassis features: Chassis height is only 3RU; houses up to 16 high density modules · Highest density optical transport chassis in the industry · 5. 3 transport modules per 1RU of rack space · Compatibility with the Prisma II HD modules AC or DC powered · Two slots on the rear of the chassis for AC modules ­ modules are field replaceable, redundant and load sharing · DC power can be wired directly to the chassis without the need for a power supply module ­ reduces deployment costs; redundant power connections provide power sharing from chassis-to-chassis All RF connections are made in the rear of the chassis · RF connections for each module are made by a high-reliability blind-mate connection on the inside backplane ­ no need to physically connect the RF cables to each module; very easy to plug-and-play All optical connections are made in the front of the chassis · Laser modules are designed with optical bulkheads at a 45 degree angle for eye protection as well as for improved fiber management · A fiber trough has been designed into the front of the chassis for improved fiber management · A dedicated access conduit has been designed into the chassis to help route fiber from the front and rear of the chassis; integrated fiber puller A local craft port is provided on the front of the chassis for convenient installation setup. The communication connections are located at the rear of the chassis; IN/OUT connections include the Element Management, the ICIM, and the alarm contact closure block. Three field replaceable fans on the rear of the chassis; the system can run on two fans in the event of a single fan failure. Excellent thermal design yields superior power efficiency, operating at approximately 54 watts per rack unit · Each high density modules dissipates approximately 7. 5 Watts.
