Product Description Safety
The EM125-N5 from E20 Communications is a duplex SC transceiver designed for use in Gigabit Ethernet applications. It operates with a single +5V power supply. The transceiver complies with the industry standard 1x9 footprint and meets the mezzanine height requirement of 9.8 mm. Each EM 125-N5 transceiver consists of a transmitter optical subassembly, a receiver optical subassembly and an electrical subassembly. All are housed in a plastic/metal package.

The transmitter consists of a high-performance 850-nm VCSEL and the receiver consists of an integrated GaAs PINpreamplifier.

All EM125-N5 transceivers also include a Signal Detect circuit, which provides a TTL or ECL logic high output when a usable input optical signal level is detected.

Electromagnetic Interference (EMI) Safety
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, and 3) VCCI in Japan.

To assist the customer in managing the overall equipment EMI performance, the EM125-N5 transceivers have been designed to perform to the specified limits. All transceivers comply with FCC Class B limits.

Immunity Safety
The EM 125-N5 transceiver has been designed to provide good immunity to radio-frequency electromagnetic fields. Key components to achieve the good electromagnetic compliance (EMC) are the internal shields, the metal housing, and the chassis shield.

Eye Safety
The EM125-N5 850-nm VCSEL-based transceivers have been designed to meet Class 1 eye safety and comply with FDA 21 CFR1040.10 and 1040.11 and the IEC 825-1.
