OPTICAL INSIGHTS BLOG
The broadcast industry is undergoing one of the most significant transformations in its history. As audiences demand instant, high‑resolution content across multiple devices and platforms, traditional SDI‑based workflows can no longer keep pace. The shift toward IP‑based production, virtualized environments, and cloud‑native operations is accelerating—and at the center of this evolution is optical circuit switching (OCS).
The POLATIS® family of all‑optical switches, from HUBER+SUHNER, provides the flexible, scalable, and future‑proof foundation broadcasters need to thrive in this new landscape.

Why the Industry Is Changing
1. Explosive growth in digital content consumption
Ultra‑high‑speed internet access and always‑on devices have radically shifted expectations. Consumers now want instant access to content on phones, tablets, laptops, and beyond—not just traditional TV screens.
2. Evolving video standards
From SD to HD, 4K, 8K, HDR, and even 32K formats, the growth in resolution is pushing bandwidth requirements to their limits. Traditional SDI over coax simply cannot scale affordably or efficiently.
3. Migration to SMPTE ST 2110 workflows
The shift toward ST 2110 makes media streams look more like IT traffic—packetized, routable, flexible. Fiber has become the new physical layer standard thanks to its performance, reach, and low signal degradation.
Why Optical Circuit Switching Matters
OCS replaces manual, error‑prone fiber patching with software‑controlled routing at the physical layer. The result: smart, automated, ultra‑low‑latency infrastructure that supports any format, any protocol, at any data rate

Key Advantages of POLATIS® OCS
Traditionally, telecom and data systems relied on electronic packet switches - Ethernet, IP/MPLS, or
InfiniBand - involving multiple Optical-Electrical-Optical (OEO) conversions. These conversions introduce
latency and power overhead, which become significant at scale.- Protocol & data‑rate agnostic—future‑proof for new video standards.
- Ultra‑low loss and near‑zero latency—ideal for live production.
- Supports all video/audio formats, including ST 2110 and legacy SMPTE standards.
- Handles single, mixed, and multi‑wavelength signals (TDM, CWDM, DWDM).
- Full software control, ready for SDN, orchestration systems, and broadcast automation.
- Optional optical power meters for real‑time signal monitoring.
- Optional protection switching for resilient fiber backbones.
- Eco‑friendly, low‑power operation.
- Matrix sizes from 16×16 to 384×384 ports.
Where OCS Delivers the Most Impact
There are several high‑value applications where OCS transforms operational efficiency, reliability, and cost structure.
1. Outside Broadcasting (OB)
Live events—especially motorsports and large‑venue sports—require redundant fiber backbones and dozens of nodes for routing video, audio, telemetry, and timing data.
OCS enables:
2. College Sports Broadcasting
American universities run broadcast operations rivalling major networks, often across sprawling campuses.
OCS supports:
3. Virtual Studio Expansion
When studio space in major cities becomes too expensive, OCS makes it practical to extend production to satellite locations.
Benefits include:
Companies increasingly rely on internal broadcast networks for town halls, training, corporate events, and global communications.

OCS enables:
- Automated routing of diverse fiber paths
- Simplified management of complex infrastructures
- Signal equalization from remote devices using integrated attenuation
2. College Sports Broadcasting
American universities run broadcast operations rivalling major networks, often across sprawling campuses.
OCS supports:
- Centralized production with fiber‑rich campus networks
- ST 2110‑based workflows
- Dynamic routing to multiple venues (stadiums, arenas, pools, training facilities)
3. Virtual Studio Expansion
When studio space in major cities becomes too expensive, OCS makes it practical to extend production to satellite locations.
Benefits include:
- Resource sharing between main and satellite studios
- Seamless operator experience (satellites feel “local”)
- Protection switching for tie‑lines
Companies increasingly rely on internal broadcast networks for town halls, training, corporate events, and global communications.
OCS enables:
- Low‑latency, scalable broadcast links across buildings or campuses
- Rapid deployment for on‑demand production
- Support for global, multi‑site broadcast
Integration and Operational Efficiency
POLATIS® OCS integrates cleanly into automated broadcast environments with:
- Software‑defined networking support
- Multiple APIs and driver availability for major broadcast systems
- Central monitoring of link health and power levels
- Significant reductions in troubleshooting time and technician workload
Conclusion: A Smarter, More Agile Future for Broadcasting
As broadcast workflows move deeper into IP and fiber‑based architectures, the need
for a flexible, automated physical layer becomes essential. POLATIS® optical circuit
switches deliver exactly that—helping broadcasters:
- Reduce costs
- Enhance resilience
- Improve production speed
- Maximize asset utilization
- Prepare for the next generation of video formats
