This QSFP+ Gen2 optical module is optimized for environments requiring high throughput, reduced latency, and improved power efficiency. It supports parallel optical transmission across multiple channels, enabling efficient data transport between network switches, routers, and server systems.

40GBASE-SR4 Extended Reach Optical Transmission Architecture

The Finisar FTL410QE2C-G1 operates on the 40GBASE-SR4 standard, which utilizes four parallel optical lanes to achieve a combined data throughput of 40 Gigabits per second. Each lane operates at 10Gbps, allowing simultaneous transmission and reception of data streams across multimode fiber infrastructure.

What differentiates the G1 variant is its extended reach capability, enabling reliable optical communication up to approximately 150 meters depending on fiber quality, connector integrity, and environmental conditions. This extended reach makes it suitable for larger data center layouts, campus interconnects, and structured cabling environments requiring greater distance flexibility.

The SR4 architecture is specifically designed for short-to-medium range optical transmission, making it ideal for intra-facility networking where high-speed data exchange is required between racks, rows, or adjacent buildings within enterprise campuses.

Parallel Optics Transmission Mechanism

The Finisar FTL410QE2C-G1 utilizes a parallel optics architecture that distributes data across four independent transmit and receive channels. Each channel operates simultaneously to deliver aggregated 40G throughput while maintaining signal integrity and synchronization.

This parallel design significantly reduces latency compared to serialized single-lane transmission systems. It also enhances scalability by allowing network engineers to increase bandwidth capacity without requiring fundamentally different cabling architectures.

Parallel transmission is particularly beneficial in high-density data center environments where efficiency and performance consistency are critical for workload distribution and application responsiveness.

150-Meter Extended Reach Multimode Fiber Capability

The extended reach capability of the Finisar FTL410QE2C-G1 sets it apart from standard SR4 modules by supporting longer-distance transmission over OM3 and OM4 multimode fiber. This enhancement enables network deployments across larger physical layouts without requiring single-mode fiber upgrades.

With up to 150 meters of operational range, this module supports expanded data center architectures, including multi-row switch configurations, distributed server clusters, and inter-building connectivity within enterprise campuses.
