Finisar introduced a number of new products at ECOC in Rome, including 200G and 400G transceivers such as the 400G QSFP-DD DR4, 400G QSFP-DD eLR8 (extended-reach), 200G QSFP56 FR4 and 200G QSFP56 eFR4. The company also demonstrated its first 64GBd Integrated Tunable Transmitter and Receiver Assembly (ITTRA) and a self-tuning feature for tunable DWDM modules.
Components and Subsystems
Malfunctions or failures in optical backbone networks are the nightmare of any network operator and can result in nerve-wracking and often costly repairs. Insertion loss, return loss and the ability to withstand high power densities are decisive criteria that should be considered when selecting the suitable connector.
This week, at the NGON & DCI 2018 event in Nice, France, Acacia Communications announced general availability of their new high-speed coherent optical modules for ‘ZR’ applications. The new CFP and CFP2 pluggable modules are designed to meet the growing need for capacity in network access and edge applications.
The ZR specification supports the unamplified transmission over distances greater than 40km, typically out to 80km and sometimes beyond over singlemode fibre - to address demands for growing capacity in network access, edge, and enterprise campus applications.
Attenuators are used to adapt the transmitted light power to the characteristics of the implanted receiver. The in-line fixed attenuators (OAF) offer excellent reliability and repeatable amount of light loss (attenuation) via a doped fiber. This results in wavelength independent and stable attenuation values for typical wavelength bands used in telecommunication applications (1260-1360 and 1460-1580 nm). They are suitable for optical power up to 20dBm.
CommScope has upgraded its microwave antenna portfolio with the introduction of two new long-haul antenna product lines – USX and HX – into its Sentinel and ValuLine ranges. These are designed to ultimately replace the company’s existing long-haul antennas, providing next generation performance for cellular, broadcast, telecom and private networks.
Finisar has introduced a 100G serial FR transceiver in the popular QSFP28 form factor for inter-data centre, transport and router applications with 2km reaches.
Previewing at the recent OFC conference and exhibition in San Diego, the module leverages a standard 4x25G electrical interface, so that it plugs into standard QSFP28 slots, but employs just one serial 100G PAM4 optical channel. Once deployed in sufficient volume, it is expected to replace existing 100G QSFP28 CWDM4 modules. The company also plans to introduce a 500m DR version of this module.
Amongst its new product launches at the recent OFC conference and exhibition, Finisar introduced what it says is the industry’s first 400G QSFP-DD transceiver and active optical cable for switching and routing applications.
Finisar launched a new product family at this year’s OFC conference in San Diego, complementing its line of coherent components and Analog Coherent Optics (ACO) transceivers. Called the Integrated Tunable Transmitter and Receiver Assembly (ITTRA), the new product family is heralded as the industry's smallest fully integrated coherent optics assembly.
The MIL-83526 DM connector is the most recent product developed for harsh environments. It incorporates four termini based on DIAMOND's two-component ferrules, assembled with our Active Core Alignment (ACA) process for unparalleled optical performances. This connector is available for MM, SM (PC/APC) and small core single mode fibre, polarization-maintaining (PM) fibre, and other specialty fibre types. Furthermore, this connector can also include electrical contacts for hybrid E/O applications.
Cost and compatibility can make a compelling case for pushing 100Gb/s bandwidth over a single optical channel, both as individual links and supporting 400Gb/s Ethernet, finds Andy Extance
Robin Mersh takes a look at how the industry is creating next-generation optical access fit for 5G
Technological advances to aid the increasing demand for bandwidth, on the path towards the terabit network, should lead to optical signals that are flexible and adaptive, like water, argues Dr Maxim Kuschnerov and Dr Yin Wang
