News and BusinessAccording to the 4Q21 Transport Applications Report from market research firm Cignal AI, shipments of 400ZR/ZR+ modules surged in 4Q21 as Cisco (Acacia) and Marvell rapidly scaled up production capacity. It adds however, demand from cloud operators is still exceeding supply, which will be increased this year as vendors such as Ciena, Neophotonics, and II-VI […]
Technologies and ProductsAnritsu Corporation has upgraded its Network Master Pro 1040A to support tests of 400GBASE-ZR standard optical modules, facilitating low-cost DCI. The company has also developed its optional Ethernet 4x100G N Port BERT and Ethernet 2x200G N Port BERT M1040A software solutions for breakout-type communications quality tests to reduce DCI test workloads. Anritsu says these upgraded […]
News and BusinessII‐VI has shipped its 400G ZR+ QSFP-DD-DCO transceivers, claimed to be the world’s first with 0 dBm output power that can plug directly into QSFP-DD transceiver slots on IP routers, to Windstream Wholesale for field qualification. II-VI and Windstream partnered in October 2021 to fast-track the development of high output power 400G transceiver technology that […]
Technologies and ProductsNeoPhotonics has announced availability of its extended case temperature QSFP-DD 400G ZR modules with an operating temperature range of up to 80oC. The 400G ZR modules utilise NeoPhotonics’ coherent optical components including its Silicon Photonics Coherent Optical Subassembly (COSA) and low power consumption, ultra-narrow linewidth Nano-ITLA tuneable laser. Each of these components can be operated […]
Technologies and ProductsFujitsu Optical Components Limited (FOC) has released a 400G ZR+ transceiver that enables coherent WDM transmission greater than 120km in the same form factors (QSFP56-DD and OSFP) as its 400G ZR transceiver. Both of these transceivers use advanced coherent technology to enable higher bandwidth capacity and lower cost per bit compared to existing 100G WDM […]
