Description
Fortinet FN-TRAN-QSFPDD-SR8 400G Optical Transceiver Module
Overview
The Fortinet FN-TRAN-QSFPDD-SR8 is a 400G QSFP-DD transceiver designed for high-speed, short-range data transmission over multi-mode fibre (MMF). Featuring eight parallel lanes of 50Gbps, this module is ideal for high-performance computing (HPC), large-scale enterprise networks, and hyperscale data centres.
With support for short-reach (SR) applications, the FN-TRAN-QSFPDD-SR8 delivers ultra-fast connectivity with low latency, making it a perfect choice for high-bandwidth environments such as AI workloads, cloud services, and storage area networks (SANs).
Key Features & Benefits
High-Speed 400G Performance
Delivers 400 Gbps of data transfer over eight lanes (8x50Gbps).
Uses QSFP-DD (Quad Small Form-Factor Pluggable Double Density) for enhanced bandwidth.
Supports PAM4 modulation, increasing data rates without added power consumption.
Optimised for Short-Distance Connectivity
Designed for data transmission up to 100m over OM4 multi-mode fibre (MMF).
Uses MPO-16 connector, allowing efficient high-density cabling.
Ideal for intra-data centre connectivity, including rack-to-rack and server-to-switch communication.
Energy-Efficient & Scalable
Low power consumption (<10W), reducing operational costs.
Enables seamless scaling of existing network infrastructure without costly overhauls.
Provides a cost-effective alternative to long-range transceivers for short-haul data transmission.
Fortinet Compatibility & Reliability
Fully compatible with Fortinet network switches, routers, and security appliances.
Designed to meet stringent Fortinet quality and security standards.
Ensures high-speed, secure, and low-latency communication within enterprise environments.
Use Case Scenario: Data Centre Expansion
A financial services firm is expanding its data centre operations to support real-time trading, fraud detection, and AI-driven analytics. The existing 100G network is insufficient to handle the growing demand for low-latency, high-bandwidth processing.
By integrating Fortinet FN-TRAN-QSFPDD-SR8 modules, the firm upgrades to 400G connectivity, reducing network congestion and increasing data throughput across server clusters. This upgrade enhances application performance, reduces transaction delays, and ensures compliance with high-speed trading requirements.
