Description
The 25 and 50-pair series of protected terminal blocks provide a system for terminating
incoming cables and station pairs at the subscriber premises. These blocks are available in
stub-less R66 quick-clip type terminals with 3-element gas tube protection. To complete
this system, a weather-tight aluminum enclosure is offered. The enclosure is accessed
using a 216-type tool.
The quick-clip type termination fields are available in four clip multiples, and blocks can
have one or two terminal fields. Single-field blocks are wired directly to the protectors, a
lower cost alternative if cross-connect capability is not needed. Double-field blocks have a
protected field and a cross-connect field. The protected field is used to terminate the OSP
cable while the cross-connect field terminates subscriber wires; it is not connected to the
protectors. In comparison, for typical applications jumper wires are used to connect the
protected field to the cross-connect field.
All blocks are constructed of a high dielectric,
self-extinguishing thermoplastic and are
marked for protected and unprotected pairs.
Application
The 25 and 50-pair series terminal blocks are
ideal for apartment buildings or mediumdensity commercial or industrial buildings
where the maximum feeder cable is 50-pair
or less. They are used as an indoor application
where protection is required and cross-connection of feeder and subscriber cable pairs is
desired. The units may also be used as a
demarcation point for connecting to interconnect systems.
