Section 1 – Conflict Minerals Disclosure

Item 1.01 – Conflict Minerals Disclosure

Company Overview

Optical Cable Corporation (or OCC®) manufactures a broad range of fiber optic and copper data communication cabling and connectivity solutions. OCC’s products include fiber optic and copper cabling, fiber optic and copper connectors, specialty fiber optic and copper connectors, fiber optic and copper patch cords, pre-terminated fiber optic and copper cable assemblies, racks, cabinets, datacom enclosures, patch panels, face plates, multi-media boxes, and other cable and connectivity management accessories.

Conflict Minerals Disclosure

Section 1502(e)(4) of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (“the Act”) defines conflict minerals as columbite-tantalite (tantalum), cassiterite (tin), wolframite (tungsten) and gold, commonly referred to collectively as “3TG”. OCC evaluated its current product lines and determined that certain manufactured products contain 3TG.

Certain of the 3TG minerals are contained in some of the wire and metal components used by OCC in the connector manufacturing process. On a more limited basis, OCC uses certain 3TG minerals in the production of products in its fiber optic cable product lines.

OCC does not make direct purchases of raw ore or unrefined minerals or any direct purchases from recycled or scrap sources, and makes no direct purchases in the Democratic Republic of the Congo (“DRC”) or its adjoining countries. OCC has conducted a country of origin inquiry in good faith by identifying suppliers of the parts used in OCC products that are likely to contain 3TG and requesting that suppliers respond with a completed Conflict-Free Sourcing Initiative (“CFSI”) Conflict Minerals Reporting Template. This template facilitates disclosure and communication of information regarding the origin of conflict minerals, smelters that provide material to a company’s supply chain, and supplier due diligence.

OCC’s due diligence measures included:

Conducting a supply chain survey with all suppliers of components that contain 3TG using the CFSI Conflict Minerals Reporting Template.

Tracking and reviewing responses to assess reliability.

Following up with suppliers who failed to return responses or returned incomplete or inconsistent responses. OCC received valid responses from 32 of 36 surveyed suppliers.

Reviewing the smelters and refiners identified in the supply chain survey to determine location of the smelters and refiners indicated by the respondent and that the respondent has provided an indication of the smelters and refiners “conflict free” status.

Making additional inquiries of respondents if questions arose as to the “conflict free” status.

Forty-seven percent of the suppliers who responded to the survey reported that the 3TG minerals in the parts they sell to OCC did not originate in the DRC or adjoining countries. However, the remaining suppliers reported that the minerals contained in their products may have originated in the DRC or adjoining countries, or were unable to specify the origin of the minerals. Please see the attached Conflict Minerals Report (Exhibit 1.01). Based on the information received, OCC does not have sufficient information to determine whether the necessary 3TG minerals contained in our products directly or indirectly financed or benefited armed groups in the DRC or its adjoining countries.

A copy of OCC’s conflict minerals disclosure herein is publicly available at: www.occfiber.com under “Investor Relations”.
