Description

The 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. The

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.

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 short reach applications. The characteristics are

performed in accordance with Telcordia Specification GR-468-CORE.

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.
