1 x SFF, Duplex LC Connector, 80 CSEL for Multimode Fiber, RoHS Compliant Extended Operating Temperature from -0 to +8 RoHS Pb Features Applications Gigabit Ethernet links Fibre Channel links at.0 Gbps High speed backplane interconnects Switched backbones 80 CSEL Data Rate:.Gbps, NRZ Single +. Power Supply RoHS Compliant and Lead-free AC/AC Differential Electrical Interface Compliant with Multi-Source Agreement (MSA) Small Form Factor (SFF) x Footprint Duplex LC Connector Compliance with specifications for IEEE-80.z Gigabit Ethernet (0Base-SX) at. Gbps Compliance with ANSI specifications for Fibre Channel applications at.0 Gbps Eye Safety Designed to meet Laser Class comply with EN08- Description The CT-0NSR-SBL-A from is a high performance and cost-effective module for serial optical data communication applications specified for multimode of. Gb/s. It operates with +. power supply. The module is intended for multimode fiber, operates at a nominal wavelength of 80 and complies with Multi-Source Agreement (MSA) Small Form Factor (SFF) x footprint. Each module consists of a transmitter optical subassembly, a receiver optical subassembly and an electrical subassembly. All of them are housed in a plastic package and the combination produces a reliable component. The module is a dual fiber connector transceiver designed for use in Gigabit Ethernet applications and to provide IEEE-80.z compliant link for.gb/s short reach applications. The characteristics are performed in accordance with Telcordia Specification GR-8-CORE. EMC Most equipment utilizing high-speed transceivers will be required to meet the following requirements: ) FCC in the United States ) CENELEC EN0 (CISPR ) in Europe To assist the customer in managing the overall equipment EMC performance, the transceivers have been designed to satisfy FCC class B limits and provide good immunity to radio-frequency electromagnetic fields. Eye Safety The transceivers have been designed to meet Class eye safety and comply with EN 08-. F,0 Industry E. Rd. I., Science-Based Industrial Park, Hsinchu, Taiwan, R.O.C. Page of ersion B
