Watch - 5 Steps to DWDM

Data is the most essential property in any organization, and automatic back up of the data at a remote location has become essential for the survival of the organization. This has lead the changes in the role of data centers over the last few years; From offering basic space or power rental services, to providing full scale connectivity and disaster recovery that have become critical to enterprises. The need to comply with standards and regulations has also driven changes in the way data centers are perceived and used.

Transport high capacity data and storage services over long distances with Layer-1 encryption and link redundancy.

Data Center Interconnect (DCI) is typically deployed in mission-critical applications and in industries carrying sensitive data, which require link redundancy, equipment protection and encryption for security. Today’s users expect all data to be available from everywhere and at any time, facilitating a demand for seamless DCI. High bandwidth applications such as data backup, synchronization of databases, financial transactions, and cloud services are driving the need for high capacity data transport capabilities between data centers.

High Capacity DCI Deployment

DWDM and OTN technologies are the most common solution for DCI connectivity, as they enable the transport of high capacity data over a single fiber, transparently and at low latency over long distances. PacketLight devices facilitate building private optical backbone between data centers with unlimited capacity, supporting a flexible mix of services, such as 10G/25G/40G/100/400G Eth and 8/16/32G FC.

PacketLight devices also enable scaling of existing network capacity without replacing existing OTN/DWDM infrastructure, by adding 100G/200G/400G alien wavelengths. This cost-effectively upgrades existing infrastructure and provides the flexibility to use different vendor hardware seamlessly over the same backbone, forming a disaggregated open line system solution.

Redundant Network

PacketLight equipment provides reliable, high-capacity networks with redundancy, critical in industries where information must be available at all time, and downtime is not an option. The network supports different levels of protection, including 1+1 facility protection using an optional integrated optical switch, equipment protection using Y-cable or OTN cross-connect. The units are designed with power and fan redundancies, further ensuring reliability.

Layer-1 Encryption for High Level of Security

Transferring the organization’s sensitive data between remote sites requires high level of security, as tapping fiber optic is not as complicated as it was once thought. The use of Layer-1 encryption at the transport layer maintains the confidentiality, data integrity and authentication of the data. This enables carriers to offer secured infrastructure to customers that demand high level of data protection.

PacketLight’s Layer-1 encryption devices perform GCM-AES-256 encryption on Layer-1 without any degradation to the full bandwidth of GbE/10/40/100/400Gb Ethernet and 1/2/4/8/16/32G Fibre Channel services. The solution is NIST FIPS 140-2 and Common Criteria EAL2 certified, and complies with Commercial National Security Algorithm (CNSA) Top Secret Suite B 2015 requirements for GbE/10/40/100/400Gb Ethernet.

DWDM/OTN Connectivity for Short and Long Haul

PacketLight solutions span across all range of distances, from short haul campus solutions to metro, to long haul, with optimal products for each distance.

The devices integrate optical amplifiers, mux/demux, DCMs and optical switch in a low power consumption 1U reducing space and simplifying operation, to deliver full DWDM/OTN connectivity for long haul networks. In addition, they use high-performance FEC (forward error correction) to meet the challenges of high link attenuation and OSNR, with minimal intermediate sites.

Scalable Data Center Interconnect Solutions

PacketLight’s 1U devices are highly integrated and cost-effective. They form a multi-chassis, which can expand at any time to add more capacity, without link downtime. The devices are easy to install, enable fast network deployment, take up minimal rack space and have low power consumption, significantly reducing OPEX and CAPEX.

Data centers use high-end DWDM optical network solutions for transporting multiple 10/40/100/400Gb Ethernet services to satisfy the increase in demand for high bandwidth. As data capacity increases, the need for economical rack space and power consumption has become more crucial to create cost effective, scalable networks.

Performance Monitoring

As the scale and capacity of data that needs to interconnect between colocations grow, internet exchanges and data centers rapidly increase fiber and bandwidth on each link. The health of the DWDM fiber link and the traffic it carries must be monitored, including alerts. PacketLight’s embedded high-level performance monitoring (PM) solution provides full visibility on the fiber infrastructure and health of the transported data.

Connectivity between data centers is becoming more important, and providers are depending on a reliable, secure, high-capacity DWDM network backbone that is easy to operate, maintain, and grow.
