Unlocking High-Bandwidth LED Performance: The Fiber Receiving Card Advantage
EXECUTIVE SUMMARY
- Vanguard Fiber Receiving Cards represent a critical advancement in display technology by replacing conventional copper wiring with SFP fiber optic transmission.
- The Fiber Receiving Cards' primary value proposition centers on achieving superior bandwidth (5 Gb/s) and a significantly increased single-run loading capacity of up to 2.8 million pixels.
- Vanguard Fiber Receiving Cards provide total immunity to Electro-Magnetic Interference (EMI).
Fiber Receiving Cards
The Fiber Receiving Card is Vanguard’s next-generation receiving card engineered for high-end, fine-pitch fixed installations and demanding rental applications.
By replacing conventional multiple copper Ethernet wiring with SFP fiber optic transmission, Vanguard provides the following technical specifications:
- Bandwidth: 5 Gb/s (five times standard 1G systems)
- Single-run loading capacity: Up to 2.8 million pixels at 60Hz
- Loading capacity per card: 7684x432 pixels
- Transmission distance: Up to 2km
While standard receiving cards require multiple copper cable runs and complex infrastructure, the Fiber Receiving Card consolidates these into a single fiber connection. It features:
- Redundancy stack-loop backup, dual-card, and dual power supply
- Frame rate: 240Hz with HDR10/HLG support
- 14-bit per-pixel dual-layer calibration and dynamic thermal compensation
A Fiber Receiving Card has higher bandwidth capacity, useful for very high-resolution or high-refresh-rate content, or daisy-chaining many cabinets on one run.
A Fiber Receiving Card is immune to Electro-Magnetic Interference (EMI)—important near power infrastructure, broadcast environments, or stadiums with heavy electrical noise.
Fiber optic technology significantly increases data throughput to support higher resolutions and larger pixel counts.
Higher bandwidth: Fiber supports higher bandwidth, therefore data throughput, which helps with higher-resolution content, higher refresh rates, HDR signals, or driving larger pixel counts per run without needing to split into more cable segments.
When we talk about "fiber connections," we are actually looking at two distinct parts: the fiber optic cable itself (which carries the light) and the physical connectors (which plug into the network equipment).
Below is a breakdown of the materials used in both components.

The VF1 is a new-generation fiber optic receiving card developed by Vanguard for the company’s high-end fine-pitch fixed installation displays and flexible rental applications. It adopts an SFP fiber optic interface and can support either multimode or single-mode optical fiber, with a single fiber transmission rate of up to 5 Gb/s. The product supports a maximum loading capacity of 768 × 432 pixels and up to 32 groups of parallel data or 64 groups of serial data. The product measures just 145mm × 45.0mm × 14.7mm and connects directly to the cabinet HUB through a high-density connector.
From the SVC Judges: “These two products are a really great response to the challenges presented by the conventional copper IP-based dvLED transport solutions.”
From the AVT Judges: “This product is a really great response to the challenges presented by the conventional copper IP-based dvLED transport solutions.”
The Fiber Optic Cable
A standard fiber optic cable is composed of several layers, each utilizing specific materials to ensure light travels efficiently and the cable remains protected.
Fiber optic cables utilize layered materials like silica glass, Kevlar, and specialized polymers to ensure efficient light transmission and physical durability.
The Core (The Light Path)—Glass (Silica): The vast majority of fiber networks use ultra-pure silica glass (silicon dioxide). This glass is exceptionally clear to allow light pulses to travel miles without losing signal.
The Cladding (The Reflector): The cladding is made of the same base glass material as the core but with a slightly lower refractive index. This difference in material density creates a "mirror" effect inside the fiber, bouncing the light back into the core so it doesn't escape.
The Coating / Buffer (The Protector): Usually made from acrylate polymers, silicone, or polyimide. This layer wraps around the cladding to absorb shocks and protect the delicate glass from moisture and microscopic scratches.
Strength Members (The Muscle): Strands of Kevlar or fiberglass are wrapped around the core and buffer. This prevents the glass fiber from snapping when the cable is pulled during installation.
The Outer Jacket (The Shield): The outermost casing is typically made from plastics like Polyvinyl Chloride (PVC), Polyethylene (PE) for outdoor durability, or Low Smoke Zero Halogen (LSZH) plastics to prevent toxic fumes in the event of a fire.
The Fiber Connectors
The connector at the end of the fiber cable (such as an LC, SC, or ST connector) requires highly precise materials to align two microscopic glass cores perfectly. The most critical part of the connector is the ferrule—the rigid tube that holds the exposed end of the fiber.
Precise zirconia ceramic ferrules are essential for maintaining perfect alignment and signal integrity at connection points.
Ceramic (Zirconia): This is the gold standard and the most common material used for ferrules today. Zirconia ceramic is incredibly hard, temperature-stable, and can be polished to a perfectly smooth finish, ensuring the tightest possible connection between two glass fibers.
In short, a standard high-speed fiber connection relies on ultra-pure silica glass to transport the data, Kevlar and plastics to protect it, and zirconia ceramic to perfectly align it at the connection point.
Vanguard Fiber Receiving Cards provide mission-critical display performance for high-end installations by utilizing fiber to offer unmatched bandwidth, reliability through redundancy stacks, and complete EMI immunity.
