24 I ICT TODAY Pulling on pre-terminated cables can often turn out to be more complicated than anticipated. Connectors need to be protected from excessive mechanical pulling force, impact, and accidental removal of dust caps. Unless a strategy is planned to pull on pre-terminated cables, installers often find themselves having to resort to do-it yourself (DIY) schemes, lengthening installation times. Since many connectors are significantly larger in diameter than the cable itself, pulling through holes much larger than the cable is often assumed to be unavoidable. This makes it difficult to reuse existing small diameter holes or conduits and requires that new holes be drilled to a diameter in excess of 3/8 in (≈9.5 mm). Accordingly, there is an opportunity to minimize damages to building structures while pulling on pre-terminated cables that can have their connector outer bodies easily field installed. Pre-terminated cable pulling adapters (PCPAs) are a possible solution to ease the pulling of pre-terminated cables in passive optical network (PON) or passive optical LAN (POL) applications. To learn more about PONs, POLs, and the latest standards and best practices, refer to BICSI's Telecommunications Distribution Methods Manual (TDMM), 14th edition. The use of pre-terminated cables as an alternative to field-terminated cables make it possible to save considerable time and expense. However, pulling directly on connectors must be avoided. Pre-connectorized cables are used for many reasons, including: • The complexity of installing field connector kits for single strand, large diameter, ruggedized optical fiber pre-connectorized cables. • The shortage of skilled labor (e.g., fusion splicing of connectorized optical fiber pigtails). • The time taken to install connectors. • The costs of testing the connectors for compliance with performance specifications.
