GIGALIGHT's Low-Latency Optical Transceiver Series: Delivering Nanosecond Value to Customers

By: GIGALIGHT
 
SHENZHEN, China - May 21, 2025 - PRLog -- GIGALIGHT has officially launched its brand-new low-latency optical transceiver series, which brings nanosecond-level value to customers. This series precisely meets the urgent demands for ultra-low latency and high reliability in data centers and high-performance computing scenarios. By optimizing optical performance and signal processing technologies, these products achieve an extremely low bit error rate (BER) without the need for Forward Error Correction (FEC), significantly reducing link transmission delays. As a result, they offer crucial performance advantages in scenarios such as financial trading, AI training, and real-time data analysis.

Core Advantage: Eliminating FEC to Reduce Hundreds of Nanoseconds of Delay

Traditional 25G/100G optical transceivers rely on FEC to ensure link reliability. However, FEC processing introduces additional latency, which can be as high as 250ns. Through innovative design, GIGALIGHT's low-latency optical transceivers can maintain a BER below 1E-12 (with a typical value of <1E-15) even when FEC is disabled. This directly eliminates the FEC processing step, saving up to 250ns of delay per link.

Product Features and Measured Performance

Below are some representative products from the series along with their test data:

Key Features
  • FEC-Disabled Switch Compatibility: The pre-FEC bit error rate (BER on Pre-FEC) meets the requirement of being less than 1E-12, fulfilling the need for systems to disable FEC and reduce latency.
  • High-Temperature Stability: All products in the series have passed rigorous 30-minute tests at 70°C, ensuring reliability under extreme operating conditions.

Application Scenarios and Interoperability
  • Ultra-Low-Latency Scenarios: Suitable for latency-sensitive fields such as high-frequency trading and distributed databases. Maximum performance can be achieved in FEC-disabled mode.

Supported Platforms

GIGALIGHT's low-latency optical transceivers have obtained compatibility certifications for mainstream switch platforms, including:
  • 25G SFP Ports: Ideal for high-performance Top-of-Rack (ToR) switches and direct server connections.
  • 200G QSFP-DD Ports: Support high-density deployments in the core and Spine layers of data centers.

Technological Upgrades, Empowering the Future

The launch of GIGALIGHT's low-latency optical transceivers not only builds upon its technological expertise in the optical communications field but also provides critical infrastructure for next-generation network architectures through its "zero-FEC latency" design. In the future, GIGALIGHT will continue to optimize product performance, facilitating a smooth evolution from 25G to 200G and assisting customers in building efficient and agile intelligent networks.
