Optical Cable Corporation (OCC) | The Buildout — AI Infrastructure
The Verdict
Optical Cable Corporation manufactures fiber optic and copper datacom cabling and connectivity products that form the physical layer inside data centers, enterprise networks, and military communication systems. Its cabling, connectors, and assemblies are the picks-and-shovels that carry the data traffic generated by AI workloads, even though OCC does not sell directly to the hyperscale data centers that train the largest models.

What We Like
- Sales order backlog surged 82% from October 2025 to April 2026, reaching $13.3 million, providing visibility into near-term revenue.
- Gross margin expanded 380 basis points to 34.2% in Q2 FY2026, as manufacturing leverage kicked in on 26.6% revenue growth.
- OCC’s long-standing fiber supply relationship with Lightera (Furukawa) has insulated it from industry-wide shortages, allowing uninterrupted production.
- Customer concentration is declining; the top distributor fell from 22.5% to 16.9% of sales over the past year, indicating broad-based demand.
- Management is evaluating capacity additions, signaling confidence that the demand inflection is durable rather than a temporary spike.
What We’re Watching
- Backlog conversion: a sustained backlog above $13 million is needed to confirm that orders are translating into shipments without new delays.
- Fiber supply: while OCC has avoided shortages so far, any disruption at Lightera could quickly constrain production.
- Raw-material costs: rising fiber and copper prices could compress margins if OCC cannot pass them through quickly enough.
- Capacity investment decision: if management hesitates to add staff and equipment despite strong demand, it may miss revenue opportunities.
The thesis that OCC is at a positive inflection is strengthening. The company moved from losses to profits in a year, backlog more than doubled, and data-center demand remains robust. The key open question is whether this is a cyclical upswing or the start of a multi-year structural growth story.
Earnings
In Q2 FY2026 (ended April 30, 2026), Optical Cable Corporation reported revenue of $22.2 million, up 26.6% from a year ago. Gross margin reached 34.2%, driving a net income of $1.1 million compared to a net loss of $0.7 million in the prior-year period. The standout metric was the sales order backlog, which climbed to $13.3 million, up 82% from October 2025.

We continue to believe the growth in the Tier 1 hyperscale data centers positively impacts growth opportunities that we are seeing in the multi‑tenant data center market sector … as well as growth opportunities we are seeing in the enterprise data center market sector.— Neil Wilkin, CEO, June 8, 2026
Management tone: Management’s tone was confident and forward-leaning, but measured. CEO Neil Wilkin highlighted ‘strong growth and momentum’ and fielded questions directly, acknowledging that OCC does not participate in hyperscale deals while emphasizing the company’s niche. The team appeared credible, with results that matched their prior qualitative guidance.
Management Guidance
Management did not issue quantitative guidance. They stated that data center markets will continue to positively impact revenue in H2 FY2026, that industry-wide fiber shortages are not expected to prevent growth, and that the company is evaluating adding manufacturing staff and machine capacity for long-term growth. Backlog remained strong as of the end of May.
Trajectory
OCC’s quarterly revenue has climbed from $16.2 million in Q3 FY2024 to $22.2 million in Q2 FY2026, with year-over-year growth accelerating to 26.6% in the latest quarter. Gross margin rose from 24.2% to 34.2% over the same period, as fixed manufacturing costs were spread across higher volumes. Both data center and military demand contributed, but management singled out multi-tenant and enterprise data centers as the primary growth driver. The sharp rise in backlog signals that growth may not slow in the near term.
The Model
The model projects FY+1 revenue of $87.1 million and EBITDA of $5 million (6.3% margin), and FY+2 revenue of $105.0 million and EBITDA of $10 million (9.5% margin). Near-term projections are anchored by the 26.6% year-over-year growth in Q2 and the $13.3 million backlog. The FY+2 step-up reflects expectation that data center spill-over demand persists, allowing OCC to sustain over 20% revenue growth and expand margins as past investments in plant and staffing leverage further.
| Metric | FY2025 | Next FY (E) | Following FY (E) |
|---|---|---|---|
| Revenue | $73M | $87M | $105M |
| YoY Growth | — | +19.5% | +20.6% |
| EBITDA | $0M | $5M | $10M |
| EBITDA Margin | 0.5% | 6.3% | 9.5% |
Projections are the median of 5 independent model runs. The model’s revenue sits 28.0% above analyst consensus.

What Could Go Right — and Wrong
- Data center demand accelerates beyond current expectations, pushing revenue growth above 30% and backlog over $15 million.
- OCC announces a significant new capacity expansion, enabling faster scaling and capturing a larger share of the multi-tenant data center market.
- Gross margin hits 35% or higher as volume leverage continues and raw material costs stabilize.
- Lightera partnership remains tight, and OCC seizes market share from competitors starved of fiber supply.
- Military/severe-duty orders contribute a second strong growth leg, diversifying the customer base further.
- Data center demand cools and backlog declines sharply, causing revenue growth to slow to single digits.
- Lightera reallocates fiber supply to larger customers, forcing OCC to extend lead times and miss shipments.
- Rising fiber and copper costs outpace OCC’s pricing adjustments, compressing gross margin back toward 30%.
- Top distributor loss or consolidation eliminates a significant portion of sales, undoing recent concentration improvements.
- Competitive pressure from Belden, Amphenol, or Corning squeezes OCC’s niche, eroding its distributor relationships.
Looking Ahead
Over the next twelve months, the primary focus is on whether the data-center-driven revenue momentum continues and whether OCC converts its capacity evaluation into concrete investments. The Q3 FY2026 report will provide the first test of backlog conversion; sustained sequential growth and a stable or rising backlog would reinforce the bull case. Management’s decision on staffing and machinery additions will be a key signal, likely by year-end fiscal 2026. If the industry fiber shortage persists, OCC’s supply advantage could become an even larger differentiator.
- Mid-Sep 2026Q3 FY2026 earnings — Tests whether $13.3M backlog converted to revenue and margin leverage continued.
- Late 2026Capacity expansion decision — Announcement of staff or machinery additions would confirm durability of demand.
- OngoingBacklog updates (quarterly) — Sustained backlog above $13M shows demand still outpacing shipments.
- H2 FY2026Data center demand commentary — Management’s assessment of whether Tier-1 spillover continues.
- Late FY2026/FY2027Fiber supply stress test — If shortages intensify, OCC’s Lightera relationship faces its most critical test.

The Company
Optical Cable Corporation manufactures fiber optic and copper datacom cabling, connectivity products, and assemblies. Its products form the physical layer that connects servers, switches, and storage inside enterprise networks, multi-tenant data centers, and military communication systems. As AI workloads drive a boom in data center construction, OCC supplies the high-density fiber cables, Category 6A/8 copper cables, and pre-terminated assemblies that are essential for high-speed, short-reach links.
The company operates three U.S. manufacturing plants — in Roanoke, Virginia; Swannanoa, North Carolina; and Plano, Texas — plus a leased warehouse. It sells overwhelmingly through wholesale distributors, giving it broad reach but limited visibility into end customers. OCC is vertically integrated only in the sense that it manufactures cable and connectivity under one roof; it sources optical fiber from long-standing suppliers, most notably Lightera, a subsidiary of Furukawa Electric.
Business Segments
Competitive Landscape
OCC competes with large, well-capitalized firms that span fiber optic cable (Corning, CommScope, Belden, AFL/Fujikura, Proterial, Superior Essex, Prysmian), enterprise connectivity (CommScope, Corning, Leviton, Legrand/Ortronics, Panduit), and harsh environment (Amphenol, Aptiv). The company’s niche is its flexible domestic manufacturing and distributor-centric model, which allows it to serve Tier-2 and enterprise data centers without directly battling for hyperscale mega-deals.
- CorningNamed in filings; major fiber supplier with ~$18B in hyperscale LTAs. OCC management says Corning’s deals are not directly impacting OCC’s growth.
- CommScopeNamed in filings as competitor in fiber optic cable and enterprise connectivity; no specific competitive discussion from OCC.
- BeldenNamed in filings; cross-read indicates Belden’s data center cabling grew double-digits, and it is expanding solutions team.
- AmphenolNamed in filings for harsh environment connectivity; management notes OCC occupies a different niche and does not compete head-to-head on hyperscale connectors.
- AFL (Fujikura)Named in filings as fiber optic cable competitor; no specific competitive discussion from OCC.
Supply Chain
OCC sits as a small domestic manufacturer in the data-center cabling chain. It sources optical fiber from a few key suppliers and sells through wholesale distributors, limiting its visibility into end users. Neighboring manufacturers have not mentioned OCC by name, but the same demand tailwinds are evident across the sector.
