## Abstract

A hardened optical platform includes a hardened enclosure including a door that when closed environmentally seals the hardened enclosure; a first set including one of more modules; a second set including one or more modules arranged substantially perpendicular to the first set; and high-speed cabling interconnecting the first set to the second set, wherein the hardened optical platform is passively cooled with the hardened enclosure and the door being weatherproof thereby having no airflow internally from a surrounding environment.

## Claims

### Claim 1

A hardened optical platform comprising:
a hardened enclosure including a door that when closed environmentally seals the hardened enclosure;
a first set including one of more modules;
a second set including one or more modules arranged substantially perpendicular to the first set; and
high-speed cabling interconnecting the first set to the second set,
wherein the hardened optical platform is passively cooled with the hardened enclosure and the door being weatherproof thereby having no airflow internally from a surrounding environment.

### Claim 2 (depends on 1)

The hardened optical platform of claim 1, wherein the high-speed cabling is twinaxial cabling.

### Claim 3 (depends on 1)

The hardened optical platform of claim 1, wherein the first set includes any of line modules and client modules, and the second set includes switch modules.

### Claim 4 (depends on 1)

The hardened optical platform of claim 1, wherein the high-speed cabling is utilized in lieu of a backplane.

### Claim 5 (depends on 1)

The hardened optical platform of claim 1, wherein each module in both the first set and the second set include cabling only on a faceplate.

### Claim 6 (depends on 1)

The hardened optical platform of claim 1, wherein the hardened enclosure has a rectangular shape, and wherein the second set are arranged along a length of the hardened enclosure.

### Claim 7 (depends on 1)

The hardened optical platform of claim 1, wherein the hardened enclosure includes a length and a width, and wherein the second set are arranged along the length of the hardened enclosure.

### Claim 8 (depends on 1)

The hardened optical platform of claim 1, wherein the second set generates more heat than the first set.

### Claim 9 (depends on 1)

The hardened optical platform of claim 1, wherein the second set is configured to supply power to the first set.

### Claim 10 (depends on 1)

The hardened optical platform of claim 1, wherein the high-speed cabling is electrical cable, and wherein the first set further include optical ports.

### Claim 11 (depends on 1)

The hardened optical platform of claim 1, wherein each module in the first set and the second set is enclosed with a thermally conductive housing.

### Claim 12 (depends on 1)

The hardened optical platform of claim 1, wherein one or more modules in the first set include at least one cage configured to receive a pluggable optical module.

### Claim 13 (depends on 1)

The hardened optical platform of claim 1, wherein the hardened enclosure is configured to be any of pole-mounted, strand-mounted, mounted to an exterior of a building, and located in an outside plant cabinet.

### Claim 14 (depends on 1)

The hardened optical platform of claim 1, wherein the hardened optical platform is a packet switch.

### Claim 15 (depends on 1)

The hardened optical platform of claim 1, wherein the hardened optical platform is a Time-Division Multiplexed (TDM) switch.

### Claim 16 (depends on 1)

The hardened optical platform of claim 1, wherein a front cover of the door includes spaces and guides for fiber management and fiber splicing.

### Claim 17 (depends on 1)

The hardened optical platform of claim 1, further comprising a temperature sensor and circuitry configured to heat an interior of the hardened enclosure responsive to a predetermined temperature.

### Claim 18 (depends on 1)

The hardened optical platform of claim 1, further comprising a heat fins on an exterior portion of the hardened enclosure to move heat generated inside the hardened enclosure.

### Claim 19 (depends on 1)

The hardened optical platform of claim 1, further comprising a fiber and power access ports on an exterior portion of the hardened enclosure.

### Claim 20

A method comprising providing a hardened optical platform that includes
a hardened enclosure including a door that when closed environmentally seals the hardened enclosure;
a first set including one of more modules;
a second set including one or more modules arranged substantially perpendicular to the first set; and
high-speed cabling interconnecting the first set to the second set,
wherein the hardened optical platform is passively cooled with the hardened enclosure and the door being weatherproof thereby having no airflow internally from a surrounding environment.
