CALIENT Technologies introduced its Edge|640 Optical Circuit Switch (OCS) with 640 fiber-optic cross connections – up to twice the capacity of its current S320 OCS product. CALIENT uses 3D microelectrical machine (MEMS) optical mirror technology to create protocol agnostic optical connections between ports at speeds up to 400 Gbps. The all-optical nature of the switch […]
Sedona Systems, a start-up offering multi-layer IP/optical network automation and control solutions, introduced a Hierarchical Network Controller that automatically discovers, provisions and optimizes L0-L3 services across multilayer, multivendor, multidomain networks. The company said the role of its Hierarchical Network Controller is to present a single interface and simplified view of the network to service orchestrators […]
Kaiam unveiled an 8-lane, single-mode 400G transceiver in a QSFP-DD form factor at OFC 2018. The new device, which is enabled by the company’s LightScale2 architecture used in its XQX5000 series of 100GBASE-CWDM4 QSFP28 pluggables, is optimized for high-volume, low-cost manufacturing. The company said its LightScale2 platform supports both 4-lane and 8-lane 200G and 400G […]
Menara Networks has begun sampling its Coherent CFP2-DCO transceivers to select customers. Menara’s Digital CFP2-DCO “system-in-a-module”, which is powered by a 16nm Coherent Processor, provides DWDM coherent transmission for 100G and 200G per wavelength in a CFP2 MSA small form factor. It performs all necessary adaptive PM-QPSK and PM-QAM 16 modulation, digital signal processing for […]
400 gigabit Ethernet (GbE) switches will see initial shipments this year and will grow exponentially, driving the majority of data center Ethernet switch bandwidth by 2022, according to a newly published Data Center Switch Long-Range Forecast Report by Crehan Research Inc. In addition to a strong ramp of 400GbE, Crehan’s report predicts that: 400GbE data […]
At this week’s OFC 2018 in San Diego, Lumentum is conducting 100G single lambda and 400G FR4 demonstrations, as well as showcasing its catalog of optical modules and transceivers. Live 100G Single Lambda Demonstration: Lumentum’s 100G single lambda Multi-Source Agreement (MSA) compliant QSFP28 transceiver features PAM4 higher order modulation technology to transmit 100G over a […]
WDM Metro equipment revenue surpassed $7 billion in 2017, according to a recently published report from Dell’Oro Group. Huawei, ZTE, and Ciena led the market for 2017. Additional highlights from the 4Q17 Optical Transport Quarterly Report: Optical Transport revenue increased 19 percent year-over-year in 4Q17, driven largely from increased WDM Metro sales. In the quarter, […]
At OFC2018, MACOM Technology Solutions introduced single- and quad-channel linear externally modulated laser (EML) drivers for 53 Gbaud PAM-4 applications. This family of surface mount drivers enables 100 Gbps per lambda with low power and high bandwidth for 100G/400G Data Center applications. MACOM’s MAOM-005311 and MAOM-005411 feature differential inputs to provide common-mode rejection while the […]
Keysight Technologies is working with Ball Aerospace and Anokiwave to validate the first commercial 5G NR active array antenna product designs in the 26 GHz band. The Keysight 5G NR-ready measurement testbed offers the precision that base station and component designers require to extensively explore the performance edges of a new class of active antenna […]
RETN, which operates a backbone network that spans 33,000 kilometers of fiber and connects 34 countries across Europe, Asia and North America, has deployed the Infinera XT-3300 and FlexILS to scale network capacity for its international wholesale and enterprise customers. RETN previously deployed the Infinera DTN-X, XT-500 and Cloud Xpress throughout Europe and Russia.
SFR, a subsidiary of the Altice Group, is deploying Cisco Network Services Orchestrator (NSO) to simplify the entire lifecycle management for its services, automating core functions across physical and virtualized networks for both existing and new customers.
