Request InfoTyco Electronics, Communications & Industrial SolutionsTyco Electronics Corp. has released the AMP OC-3/Fast Ethernet multimode MT-RJ transceivers. The 156-Mb/s module is intended for use in SONET OC-3 multimode fiber physical layers that provide ATM and other data communications services, and the 125-Mb/s version is for use in FDDI, ATM and Fast Ethernet multimode fiber physical layer applications. They send and receive pre-encoded data over a pair of 62.5- or 50-µm-core multimode optical fibers. The modules employ 1300-nm optics and operate from a single 3.3-V power supply. They have a DC-coupled data interface that provides flexibility...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 4/27/2023Optical Time Domain ReflectometersThe D-Series of Optical Time Domain Reflectometer (OTDR) solutions from EXFO are advanced field testing tools that deliver highly accurate measurements to characterize and validate fiber links. ...Photonics.com 1/9/2024800 ZR/ZR+ TransceiverCoherent Corp.’s 800G ZR/ZR+ transceiver comes in ultracompact QSFP-DD and OSFP form factors for optical communications networks, AI, and machine learning applications.
