Agilent Extends Optical Receiver Stress Test Solution to 850nm Transceivers
Agilent Technologies has announced its complete optical receiver stress test solution will be expanded to test 850 nm multimode transceivers.
The Agilent N4917A optical receiver stress test set provides the most accurate and repeatable conformance and characterization test results. Design and test engineers in the communications and storage industry can now accurately characterize and verify standard conformance of receive optical sub assemblies (ROSAs) and transceiver modules operating up to 14.2 Gb/s, commonly used in 10 Gb Ethernet and 10 G Fibre Channel networks.
Optical component vendors are continuously driving optimization and redesign of the optical transceivers used in IEEE 802.3ae 10GbE and IEEE 8.03ba 40GbE and 100G Ethernet and for next-generation Fibre Channel networks.
The growing demand for optical short-reach connections increases the demand for testing 850 nm multimode transceivers and subcomponents. R&D and test departments need flexible test equipment that allows accurate characterization and compliance testing, in a repeatable and efficient way, for such new receiver designs.
Agilent already offers a complete optical receiver test solution for 10 GbE-LR/-ER and 10 G Fibre Channel. This solution is now extended to address testing of short-reach transceivers, such as 10GBASE-SR, 40GBASE-SR4 and 100GBASE- SR10.
The extended Agilent N4917A optical receiver stress test set provides R&D and test engineers with a complete test solution. Benefits include:
* accurate test results with calibrated injection of optical modulation amplitude (OMA), extinction ratio
