Data Center Networks
Cloud service providers are driving the rapidly growing demand for optical transceivers in hyperscale datacenters with ever-evolving requirements for higher bandwidth, lower power consumption, and longer reach. Multimode fiber continues to provide the lowest cost and lowest power connectivity for the majority of datacenter deployments with links of up to 300 meters. Active optical cables represent a simple, low-cost interconnect for short-reach interfaces of less than 20 meters. For these reaches, vertical cavity surface-emitting laser (VCSEL) technology has the proven reliability and performance to meet the demands of the modern datacenter. For longer reaches, spanning from 2 km to 80 km, single-mode fiber is preferred. Transceivers for single-mode fiber are enabled by edge-emitting lasers. They are typically based on Ethernet protocol and come in a broad range of pluggable form factors.
Enterprises of all sizes use fiber optics to run their networks. Fiber optic cables are commonly deployed across campus environments, between floors, within enterprise datacenters. Enterprises require a diversity of interoperable, standards-based equipment to perform a variety of IT functions. They run their networks over fiber optics to deliver reliable, high-speed traffic to their end users with minimal downtime. A typical enterprise network has fiber spanning an entire building across multiple floors and across campus between buildings.
Storage Area Networks
Fibre Channel has become the trusted networking protocol for mission-critical data in storage area networks. Today, it is the most widely used interface for most enterprise storage applications, including Fibre Channel switches, host bus adapters, and storage systems. Transceivers for Fibre Channel are enabled by VCSELs for short-reach transmission over multimode fiber and edge-emitting lasers for longer-reach transmission over single-mode fiber, such as in FICON applications or for transmission using wavelength division multiplexing between datacenters.
High-performance computing (HPC) is the interconnection of many computer, storage, and networking systems that unlock high levels of computational capabilities for the hardest mathematical problems, such as in weather forecasting, biotech simulations, seismic data analysis, or big data analytics. HPC is enabled by the interconnection of many individual devices using high-speed fiber optics.
