DIAMOND optical attenuators - precise and repeatable

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.

New CommScope long haul antenna product lines upgrade microwave antenna range

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 expands portfolio with next generation 100G serial QSFP28 and ‘industry first’ 50G SFP56 transceivers

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.

Finisar launches ‘industry's smallest’ coherent optics assembly at OFC 2018

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.

DIAMOND introduces the new hybrid E/O rugged connector for harsh environment

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.

II-VI Incorporated reveals new high resolution optical channel monitor for flexible grid ROADMs

II‐VI Incorporated has introduced a new CTM 1450 high resolution optical channel monitor for flexible grid reconfigurable optical add-drop multiplexers (ROADMs).

Highly flexible ROADMs that enable bandwidth optimisation across the network with dynamic data rate selection and channel width allocation are essential for the efficient build out of the global optical transport infrastructure. The CTM 1450 monitor provides visibility into capacity allocation by monitoring the DWDM spectrum at the ingress and egress points of ROADM nodes.
