Multi-Purpose Housing (CMPH™) Interconnect (IT) Series of Pedestal Enclosures
■CMPH Exterior. The exterior of the CMPH consists of a nonmetallic, two-piece, rectangular, above-grade OSP enclosure that offers easy installation, superior structural strength, 360° technician access, generous cable storage capacity, and protection against corrosion, floods, fire, weather, soil, insects, intrusion, dents and impact for fiber-optic cable splices and customer service drops in FTTP and FTTC (Fiber to the Cell Site) deployments. The two exterior pieces of the CMPH are the base and the dome. The enclosure base has ribbed walls, internal, dual-purpose, molded-in, channel grooves (which accept most metallic stakes as well as the vertical channels of the internal framework, see Figure 2), an open top, and an open bottom. Easy replacement installations and easy underground cable access is provided via the open base bottom. The toppiece of the CMPH is the locking dome, designed to overlap the base for a flood-protective bell-jar effect.
■CMPH Interior. The interior of the CMPH consists of an internal framework which supports either one, two, or three CFDP206-EL08pedestal fiber organizers mounted in the frame (hereafter referred to as the ''backboard'' or ''CFDP''). Each fiber organizer is enclosed and secured with two large locking doors, one on the CO side and the other on the customer side, that separate the drop connections from the CO feed connections. Up to 24 connections can be made with SC or FC-type pre-terminated cables at the fiber organizer's interconnect bulkhead adapters (8 per fiber organizer). Feed side cables may be either a pre-terminated type connected directly to the CO side of the bulkhead, or a loop through or stub end cable requiring sheath removal, attachment, and splicing in the provided splice tray. Connectorized fanouts or pigtails are spliced to the CO fibers and terminated at the bulkhead. Three-meter long SC or FC-type pigtails are available from Charles Industries. Customer side cables are typically a pre-terminated type with an SC or FC connector at the fiber organizer, and these connectors are routed and inserted into the corresponding-numbered adapters for each customer line placed in service. Provided with any additional fiber organizer ordered is a 3/4'' diameter split tube to facilitate feed fiber transport from the first fiber organizer to the second and third fiber organizers (Note: a minimum fan-out or pigtail length of 60'' is required). Labels are provided on the inside each door and near the bulkheads for connector-to-adapter matching. The fiber organizer also enables technicians to route, bond, and attach various cables, tubes, splice trays, fiber management D-clips, splitters or other equipment, if needed. The bonding plate enables grounding and bonding connections either inside the fiber organizer's locked compartment or outside the fiber organizer for line maintenance and testing.
