Prisma II XD High-Density Optical Platform
High-density optical platform improves performance, lowers costs and
increases reliability.
The Prisma II™ XD High Density optical platform provides network operators with unique
features that enable the deployment of a carrier-class network. Advanced features, such as
the highest module density in the industry, rugged construction and a unique design
optimized for easy module insertion, setup, and administration, make the Prisma II XD High
Density platform the key to increased network reliability, scalability and more cost-effective
deployments. The Prisma II XD has been designed to exclusively house and manage the
high density modules in a low profile 3RU chassis– without the need for an additional host
module.
Large-scale forward-path or reverse-path deployments need the versatility and
performance of Cisco’s Prisma II XD platform. 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

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
One Sheet
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.
