CASE HISTORY

The company C. had to chose if it was preferable to use pre-terminated cables or to assemble connectors "on field" in an Ethernet installation.
Typical links were 30m long, with one hundred links overall.

It was made the following table:

	Laying time	Termination time	Total laying time	Total termination time
Pre-terminated cables	40 meters/hour	0	100(sections)*30(m)/40(meters/hour)	0
Non- terminated cables	60 meters/hour	3 min	100(sections)*30(m)/60(meters/hour)	200 connectors*3min

While the non-terminated cables appeared preferable, both in terms of installation time and costs (a pre-terminated cable is more expensive and often longer than needed), the choiche went to pre-terminated cables, because field-mounted connectors weren't reliable.

By using plastic fiber, it discovered that a work which required 10 working days could be carried out in less then 4 days:

	Laying time	Termination time	Total laying time	Total termination time
Plastic fiber	100 meters/hour	>0,5 min	100(sections)*30(m)/100(meters/hour) = 30 hours	200 connectors*0,5min = 1,6 hours
