Components and Subsystems

Now available from Nokia is the Quillion family of chipsets that are designed to power next-generation massive scale access networks.

Infinera took to the show floor at the recent ECOC exhibition to reveal XR optics, a point-to-multipoint coherent optical sub-carrier aggregation technology.

Finisar’s pluggable, tunable DWDM optical transceivers enabled with Flextune™ are a great way to lower your network infrastructure CapEx by transmitting multiple data streams on a single fiber optics link.

Now available from Henkel’s Adhesive Electronics division is an adhesive designed for streamlined assembly of optical components and modules.

The Intel® Silicon Photonics 100G CWDM4 QSFP28 Optical Transceiver product family is expanding!

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.

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.
