Abstract
Abstract PROTECTION CASE FOR OPTICAL FIBER SPLICES Abstract of the Disclosure A protection case for optical fiber splices is in the form of an elongate box having ducts along each side and a plurality of packet members pivotally attached to the bottom of the case in overlapping relationship. A holder in each packet will hold at least one splice, or an attenuator and two associated splices. A cover fastens over the base of the case. The packets have the form of shallow boxes and extra fiber is coiled round in a packet, being retained by turned in edges of the top, sides and bottom. - i -

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
88 words
A protection case for optical fiber splices, comprising: an elongate box having a base member and a cover attached to the base member; an insert in said base member defining ducts at each side; a plurality of packet members pivotally attached to the base of the insert, the packet members in an overlapping relationship when pivotted down in the insert; a holding member in each packet member, for holding at least one splice; access at one end of the box for incoming fiber cable and outgoing fiber cable.
