It operates with +3.3V power supply. The module is intended for single mode fiber, operates at a nominal wavelength of CWDM and complies with Multi-Source Agreement (MSA) Small Form Factor Pluggable (SFP). Each module is integrated digital diagnostics functions via an I2C serial interface ( optional ). The 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 long reach applications. The characteristics are performed in accordance with ITU-T G.694.2 and G.695. EMC Most equipment utilizing high-speed transceivers will be required to meet the following requirements: 1) FCC in the United States 2) CENELEC EN55022 (CISPR 22) 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 1 eye safety and comply with EN 60825-1.
