# Corning: Choosing the Correct Optical Hardware

by **[Bobby Salerno](https://www.accu-tech.com/accu-insider/author/bobby-salerno)** on August 8, 2019

Optical hardware is a critical demarcation point of each network and choosing the correct optical hardware is critical to the short-term and long-term performance, reliability and security of any network.

**When choosing fiber optic hardware, you must consider the following:**

- - What are the density requirements for your current and future application needs?
    - Compatibility with existing solutions or is it a new installation?
    - Is your application rack-mounted or wall-mounted?
    - Is your application indoors in a controlled environment or outdoors exposed to weather or another harsh environment?

**Corning connector panel**  
A basic building-block component of any hardware selection is the Corning connector panel. The panel fits across the most popular Corning rack-mounted and wall-mounted hardware offerings.  Panel selection is made based on the following considerations:

- Fiber type and performance (see table below)*

| **Connector Adapter Color** | **Fiber Type/Performance** |
| --- | --- |
| Beige | OM1 (62.5 µm) |
| Black | OM2 (50µm) |
| Aqua | OM3 (50µm) |
| Blue | OS2 (Single Mode) |
| Green | OS2 (Single Mode Angled Polish) |

*Note* - Corning recommends matching fiber, connector, and adapter type for performance and identification purposes.*

- Termination type (field termination or fusion-spliced)
- Density (number of fibers required)
- Ease of use
- Application requirements
- Future requirements

**Rack-mounted solutions**

Most hardware applications and installations will utilize rack-mounted solutions. Standard telecommunications racks are divided into rack-units based on the overall height of the rack. A rack-unit is measured at 1.75” or 44.45 mm and is used to help designers maximize available space for both active and passive communications components.

Corning’s CCH (or Closet Connector Housing) is the industry standard for rack-mounted housings. Corning’s CCH product line has four offerings that vary in size and capacity based on the connectivity chosen.  Refer to the table below:

| **Part Number** | **Panel Capacity** | **Fiber Capacity (SC/ST)** | **Fiber Capacity (LC)** |
| --- | --- | --- | --- |
| **CCH-01U** | 2 | 24 | 48 |
| **CCH-02U** | 4 | 48 | 96 |
| **CCH-03U** | 6 | 72 | 144 |
| **CCH-04U** | 12 | 144 | 288 |

**Appropriate housing**

When choosing the appropriate housing for your application carefully consider current and future requirements. It is always easier to add additional capacity at the initial installation.  
Whether using traditional field-termination methods like the [UniCam](https://www.accu-tech.com/vendors/corning/unicam-2) or [CCH Pigtailed Cassettes](https://www.accu-tech.com/vendors/corning/pigtailed), no additional hardware or accessories are required when using the CCH product line. If your application does not involve a telecommunications rack, Corning has several wall-mounted offerings.

 Corning’s WCH (Wall-mounted Connector Housings) and Single-Panel Housings also offer a variety of sizes based on your application or capacity needs.Unlike the rack-mounted offerings, Corning’s wall-mounted offerings are designated by CCH Panel capacity which defines overall fiber capacity. Refer to table below:

| **Part Number** | **Panel Capacity** | **Fiber Capacity (SC/ST)** | **Fiber Capacity (LC)** |
| --- | --- | --- | --- |
| **SPH-01P** | 1 | 12 | 24 |
| **WCH-02P** | 2 | 24 | 48 |
| **WCH-04P** | 4 | 48 | 96 |
| **WCH-06P** | 6 | 72 | 144 |
| **WCH-12P** | 12 | 144 | 288 |

As before, it’s always a good idea to consider both current and future requirements.  
Additionally, if using traditional field-termination methods like the [UniCam](https://www.accu-tech.com/vendors/corning/unicam-2) or [CCH Pigtailed Cassettes](https://www.accu-tech.com/vendors/corning/pigtailed), no additional hardware or accessories are required when using the WCH product line.

**Environments**

Outdoor or Harsh Environments can negatively affect the performance and long-term reliability if careful consideration isn’t taken during hardware selection. Corning offers a full complement of wall-mounted offerings designed for these harsh environments. Both EDC (Environmental Distribution Center) and ICH (Industrial Connector Housings) meet additional NEMA and IP requirements and utilize the same CCH Connector panels for both field-termination and fusion-spliced applications.

Regardless of your hardware needs, Corning caters to it all. From installing rack-mounted hardware and terminating with a traditional mechanical splice to offering pre-routed pigtailed cassettes, making it simple and easy to order, install, and use is paramount in all hardware offerings. After all, hardware selection doesn’t have to be hard.
