Abstract

Claims (39)

1. A telecommunications assembly, comprising:

a tray, the tray having a base and a sidewall;

two cable management devices provided on the base of the tray for containing one or more fiber loops;

wherein only two cable management devices are provided on the tray facing one another in an area for containing the one or more fiber loops;

wherein the two cable management devices allow for storage of fiber loops having a length defined by a cable in a full loop having the radius of the minimum bend radius of the cable up to and including a length twice as long as the full loop having the radius of the minimum bend radius of the cable;

wherein the two cable management devices allow for storage of fiber loops wherein no linear segments are defined by the full loop having the radius of the minimum bend radius of the cable; and wherein linear segments are provided in loops greater in length than a full loop having the radius of the minimum bend radius of the cable;

wherein the cable management devices are each provided with a base, and three uprights;

wherein two uprights are on one side of the base of each cable management device, and one upright is on an opposite side of the base of each cable management device;

wherein when the cable management devices are mounted on the tray for containing one or more fiber loops, the cable management devices are mounted facing one another with the sides of the base with the one upright facing each other;

wherein overhanging tabs on the ends of the uprights are provided for fiber retainment;

a closure including a tray system including a plurality of the trays, and at least one component module including one of a fusion splice holder module, a WDM, or a splitter on at least one of the trays;

wherein the trays, the cable management devices, and the at least one component module are provided with compatible attachment features that allow for the cable management devices and the at least one component module to be mounted to the trays;

a plurality of fiber loops held by the two cable management devices, wherein each fiber loop has a length no more than two times the minimum bend radius.

2. The telecommunications assembly of claim 1 , wherein each cable management device includes a dovetail shaped interlock structure for connecting to the base of the tray.

3. A telecommunications assembly, comprising:

a tray;

two cable management devices provided on the tray for containing one or more fiber loops;

wherein two cable management devices are provided on the tray facing one another;

wherein the two cable management devices allow for storage of fiber loops having a length defined by a cable in a full loop having the radius of the minimum bend radius of the cable up to and including a length twice as long as the full loop having the radius of the minimum bend radius of the cable;

wherein the two cable management devices allow for storage of fiber loops wherein no linear segments are defined by the full loop having the radius of the minimum bend radius of the cable; and wherein linear segments are provided in loops greater in length than a full loop having the radius of the minimum bend radius of the cable;

wherein:

Pn=Perimeter of Path n;

Ln=Tangent Length of Path n;

Rn=Minimum Bend Radius of Path n;

P3=2*P1 (continuous range of slack storage from P1 to P3);

P1=2*Pi*R1;

P3=2*(2*Pi*R1)=2*L3+(2*Pi*R3);

R3=R1;

L3=P1*R1;

If: L3=Pi*R1,

Then: Pn can be any length>P1;

If: Pn is between P1 and two times P3;

Then: maximum of two coils are required;

If: Pn is between P1 and three times P3;

Then: Maximum of three coils are required;

If: Pn is between P1 and N times P3;

Then: Maximum of N coils are required;

wherein each cable management device includes a dovetail shaped interlock structure for connecting to the tray, the tray having a plurality of attachment arrangements for connecting to the dovetail shaped interlock structure of each of the cable management devices;

a plurality of fiber loops held by the two cable management devices, wherein each fiber loop has a length no more than two times the minimum bend radius.
