100Glight Low-Latency Optical Modules Support High-Frequency Trading Network for European Financial Exchange

Author:

A leading European securities exchange required ultra-low latency, interference-free connectivity for mission-critical high-frequency trading, where millisecond delays caused huge losses. 100Glight’s financial-grade low-latency modules delivered sub-45ns ultra-low latency, 99.9999% network availability and zero packet loss, securing uninterrupted trading and meeting strict financial compliance standards.

Client Background

A leading European securities exchange specializes in high-frequency trading of stocks, futures, and foreign exchange, with extremely stringent requirements for network latency, stability, and security. Even millisecond-level delays in high-frequency trading orders can result in huge financial losses. The legacy network optical modules suffered from large latency fluctuations, significant signal attenuation, and trading freezes caused by electromagnetic interference. The exchange urgently needed an ultra-low latency, high anti-interference, zero packet loss optical interconnection solution to ensure full-time stability of trading links, meet financial industry compliance and regulatory requirements, and realize real-time and accurate trading data transmission.

Core Challenges

Ultimate Latency Requirement: Single-link latency must be controlled within 50ns, with jitter <0.01ms, a standard unreachable by traditional optical modules.
High Reliability Imperative: 7×24 uninterrupted operation, annual downtime limited to under 30 seconds, zero packet loss and zero freezes.
Poor Anti-Interference Capability: Complex electromagnetic environment in the equipment room required strong resistance to electromagnetic interference to avoid trading link interruptions.
Strict Financial Compliance: Products must comply with financial industry security standards and support full-link data monitoring and traceability.

100Glight Solution

100Glight launched an exclusive financial-grade ultra-low latency optical module solution, deeply optimized for high-frequency trading scenarios, with core products including:

100G QSFP28 SR4 Low Latency Optical Transceiver: Single-link latency as low as 45ns, a top industry level

400G QSFP-DD DR4 Low Latency Optical Transceiver: Supports core trading backbone networks, balancing bandwidth and latency

The products adopt military-grade chips and reinforced shielding shells, delivering superior EMC (Electromagnetic Compatibility) performance to eliminate interference completely. A built-in precision DDM monitoring system tracks link status, latency, and packet loss rate in real time to meet financial compliance audit requirements. All series pass financial-grade reliability tests with MTBF exceeding 100 million hours, ensuring foolproof trading links.

Deployment & Implementation

100Glight set up a dedicated technical team to complete deployment during the exchange's late-night off-peak hours, adopting a dual-link hot backup architecture for seamless switchover between primary and backup links to avoid service interruptions. Full-scenario stress tests, latency tests, and anti-interference tests were conducted in advance with detailed inspection reports. Post-deployment, 7×24 dedicated technical support was provided for real-time response to emergencies, fully complying with financial industry security O&M specifications without data leaks or trading pauses.

Project Results

Single-link latency stabilized below 45ns, jitter <0.008ms, 30% faster high-frequency trading order processing, and significantly improved order fulfillment rate.

Superior anti-interference performance, zero electromagnetic interference failures throughout the year, and trading link availability reaching 99.9999%, far exceeding industry standards.

Full-link monitoring system enables real-time data traceability, fully meeting financial compliance requirements and passing regulatory audits smoothly.

13 consecutive months of stable operation with zero failures, zero packet loss, and zero trading delays, reducing potential financial losses by over tens of millions of euros for the exchange.

Client Testimonial

“Latency and stability are the core of high-frequency trading, and 100Glight's ultra-low latency optical modules have fully exceeded our expectations, guaranteeing ultimate smoothness of trading links with hardcore technology. Product reliability and security meet the top financial industry standards, making them an indispensable core support for our high-frequency trading network.”
