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.
Fibres & Cabling
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.
The latest addition to AFL’s MicroCore cable family is the Ultra HD MicroCore, which uses SpiderWeb Ribbon (SWR) technology.
The new cable supports high fibre density deployments in data centre and central office installation environments and is designed to optimise splicing efficiency when interconnected with the company’s Wrapping Tube Cable (WTC), a fibre optic cable that AFL says provides the smallest cable diameter and lowest weight, high-fibre count ribbon cable in the industry.
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.
Rosenberger OSI has revealed the next step on from its PerCONNECT portfolio of data centre cabling infrastructure for the office and building cabling sector in its new EcoFlex’IT. The new launch is designed to enable an efficient active and passive network from a single source, featuring active components and an overall concept that focuses on efficient and flexible new and existing network installations.
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.
OFS has expanded its portfolio of long haul products with the introduction of TeraWave SCUBA 125 Optical Fiber, which has been designed for coherent transport submarine systems.
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.
Cleaning specialist MicroCare Europe has expanded its Sticklers fibre cleaning portfolio with the introduction of three new tools and cleaners. The latest additions include a compact end-face cleaning tool; a lint-free wipe that cleans duplex connectors with one pass; and a new package size for the existing ‘Fiber Optic Splice & Connector Cleaning Fluid’.
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
