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
