With the rapid development of cloud computing, the high speed and stable interconnection of data centers (DCs) and cloud services has emerged as a mainstream networking solution.
Data Center Interconnect (DCI) and Cloud Interconnect are two specialized networking solutions, which is designed to link physically distinct computing environments via high-speed, dedicated, and secure channels. Data Center Interconnect primarily facilitates interconnection between multiple physical data centers, whereas Cloud Interconnect focuses on bridging local or private data centers with public cloud networks.
Data Center & Cloud Interconnect solutions use the advantages of fiber optic, specifically its high bandwidth, low latency, and resistance to interference to establish end-to-end high speed links. This enables the seamless and efficient exchange of data between data centers across different regions, thereby ensuring the smooth flow of data throughout the entire network domain.
Data Center & Cloud Interconnect solution adopts a design which is centered on a "layered architecture combined with dedicated channels". Structurally, it is divided into three distinct layers, the Access Layer, the Transport Layer, and the Interconnect Layer, which work in concert to establish a comprehensive, high speed transmission infrastructure powered by fiber optic products. This design ensures that interconnectivity between Data Centers (DCs) and the Cloud is efficient, secure, and reliable.
Deployed in data centers and cloud edge nodes, the access layer connects servers, storage, virtual hosts and cloud resources to the interconnect network. It performs signal conversion and aggregation to support high-speed transmission, mainly relying on fiber optic products.
As the core of the interconnect solution, the transport layer enables high speed data transmission between data centers and the cloud. Using fiber optic products and high speed transmission equipment, it delivers high bandwidth, low latency and low packet loss, ensuring stable interconnection performance.
The interconnect Layer interfaces with core network equipment of data centers and clouds, implementing routing, traffic scheduling and security protection. It safeguards data transmission against theft or tampering, supports multi-path redundancy for higher reliability, through the coordination of fiber-optic products and network security devices.
Data Center & Cloud Interconnect solution is built on fiber optic products, covering three core categories, like access, transmission, and ancillary components. Each fiber optic product performs a dedicated role and works together to form a complete fiber interconnection ecosystem. As a professional fiber optic products supplier, UnitekFiber provides full range fiber optic solutions. Below is a detailed introduction to the core fiber products used in Data Center & Cloud Interconnect:
Optical transceivers are core components in data center & cloud, responsible for converting electrical and optical signals to enable data transmission. As key devices in the access and transport layers, they are the most widely used and fundamental fiber products in the solution.
Installed in servers, storage devices, switches within data centers and access switches at cloud edge nodes, they convert electrical signals from equipment into optical signals for fiber links, and convert received optical signals back into electrical signals for servers or cloud core networks.
Available in speeds including 10G, 25G, 100G, 400G, 800G and 1.6T, 100G and 400G transceivers are mainstream for Date Center & Cloud interconnection, while 800G and 1.6T are used in high-end application for ultra-high bandwidth requirements.
Fiber optic patch cords are key interconnect product for linking switch devices and optical transceiver. They create detachable connections between fiber cables and equipment such as optical transceiver, switches and ODFs, enabling optical signal transmission as essential links at the access layer.
In data centers, MM OM4 LC fiber patch cords are widely used between optical modules and switches for 100G/400G high speed transmission, while singlemode fiber patch cords are applied in long distance inter cabinet connections for stable signal transmission. UnitekFiber provides a full range of high quality fiber optic patch cords including LC, SC, FC, ST, MU and MDC types, meeting diverse access-layer connectivity needs in data centers.
MPO/MTP cables are high density, premium fiber patchcord designed for efficient, reliable multi-core parallel optical signal transmission. They greatly reduce cable volume and save cabinet space, making them ideal for high-speed, high-density cabling in 400G/800G and above Data Center & Cloud interconnection, as well as high-speed access links at cloud edge nodes. For example, 16core multimode OM4 MPO/MTP cable are used for 400G QSFP-DD SR8 optical modules to fiber switches, replacing 16pcs simplex fiber patchcord and increasing cabling density by over 80%. In high end hybrid cloud deployments, 12Cores singlemode MPO/MTP cable work with DWDM equipment to support high density, high speed transmission for AI clusters and large scale data interactions, simplifying cabling and reducing maintenance complexity.
Bulk fiber drop cables are ideally suited for fast deployment and easy termination in both outdoor and indoor using. Designed specifically to support high performance network cabling, its high capacity fiber optic cores, such as 2/4/6/8/12 cores, offers significant space saving advantages. For data center setups, bulk fiber drop cables are commonly routed to fiber optic patch panels or communication closets, where they connected with relevant equipment to enable seamless data transmission across distinct office spaces.
The main function of an Fiber Optic Patch Panel is to facilitate the organization, splicing, distribution, and management of optical fibers. It centralizes the management of fiber optic links connecting Data Centers and Cloud, thereby simplifying fiber maintenance, capacity expansion, and troubleshooting. It is an essential piece of supporting equipment for any fiber optic communication facility. Key product variants include rack-mounted fiber patch panel featuring LC or SC connectors, such as 1U 24ports and 2U 48ports, as well as MPO/MTP fiber optic patch panel.
Fiber media converters are compact access devices that perform electrical-to-optical signal conversion, similar to optical transceivers. Deployed on edge terminals, small branches in Data Center rooms, or small access devices at cloud edge nodes, they enable fiber connectivity for a small number of equipment such as monitoring devices, mini servers and operation terminals, reducing access costs without large fiber switches. Supporting 1G and 10G speeds, with transmission distances of 10km, 20km and 40km.
Using 100G/200G/400G/800G/1.6T optical transceiver and fiber optic patchcord, we enable flexible, high speed data transmission (up to hundreds of Gbps) with intra-city latency <1ms, solving traditional public network bandwidth and latency issues for massive data scenarios.
Hot plugable optical transceiver and optical patchcord allow easy bandwidth scaling. It can add devices to boost capacity, support multi-cloud interconnections, and upgrade hybrid cloud architectures without full network restructuring, reducing costs.
Fiber optic products support remote monitoring and intelligent alerts. A unified platform enables centralized management, rapid fault handling, and the products’ high stability reduces O&M workload and costs.
