Key Features & Technical Advantages
High-Density Architecture: Utilizes a 4-parallel lanes design for short-reach modules (SR4, ESR4) and a 4-CWDM lanes Mux/Demux architecture for long-haul links (LR4, ER4).
Full MSA Compliance: Built strictly in accordance with the QSFP+ Multi-Source Agreement (MSA) to guarantee plug-and-play compatibility with industry-leading switches and routers.
Low Power & Green Design: Energy-efficient, low-power hardware design minimizes heat dissipation and operational costs inside high-density racks.
Flexible Fiber Connections: Available with Duplex LC or MPO receptacles supporting both Multi-Mode Fiber (MMF) and Single-Mode Fiber (SMF) network environments.
Electrically Hot-Pluggable: Allows safe, seamless installation, hot-swaps, and maintenance updates without requiring system downtime.
Industrial-Grade Reliability: Supports a commercial case operating temperature range of 0°C to 70°C with highly stable optical power and receiver sensitivity.
Target Applications
Data Center & Enterprise Core Switching: High-speed optical interconnects within and between core switches, edge routers, and transport equipment.
High-Performance Computing (HPC): Seamless networking for Server-to-Server Clusters, super-computing interconnects, and proprietary backplanes.
Flexible Hardware Bridging: Supports rack-to-rack, shelf-to-shelf, board-to-board, and board-to-optical backplane cabling architectures.
Versatile Protocol Support: Fully compatible with 40GBASE-SR4/LR4/ER4 Ethernet links, InfiniBand SDR/DDR/QDR applications, and legacy 10GBASE-SR link expansions.
