1 SFP, Duplex LC Connector, 850nm VCSEL for Multimode Fiber, ohs Compliant Features ohs Pb Applications Gigabit Ethernet Links Fiber Channel Links at 1.06 Gbps High Speed Backplane Interconnects Switched Backbones 850nm VCSEL Data ate: 1.25Gbps, NZ Single +3.3V Power Supply ohs Compliant and Lead-free AC/AC Differential Electrical Interface Compliant with Multi-Source Agreement (MSA) Small Form Factor Pluggable (SFP) Duplex LC Connector Compliance with specifications for IEEE-802.3z Gigabit Ethernet at 1.25 Gbps Compliance with ANSI specifications for Fiber Channel applications at 1.06 Gbps Eye Safety Designed to meet Laser Class 1, complies with EN Description he SFP-M from AAXEON is the high performance and cost-effective module for serial optical data communication applications specified for multimode of 1.25 Gb/s. It operates on +3.3V power. he module is intended for multimode fiber, operates at a nominal wavelength of 850nm, and complies with Multi-Source Agreement (MSA) Small Form Factor Pluggable (SFP). Each module consists of a transmitter optical subassembly, a receiver optical subassembly, and an electrical subassembly. All are housed in a metal package and the combination produces a reliable component. he module is a duplex LC connector transceiver designed for use in Gigabit Ethernet applications and to provide IEEE-802.3z compliant link for 1.25Gb/s short reach applications. he characteristics are performed in accordance with elcordia Specification G-468-COE. EMC Most equipment utilizing high-speed transceivers will be required to meet the following requirements: 1) FCC in the United States 2) CENELEC EN55022 (CISP 22) in Europe o 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 he transceivers have been designed to meet Class 1 eye safety and comply with EN Page 1 of 6
