Product Description
The EM250-L3 from E20 Communications is a 3.3V Small Form Factor (SFF) transceiver designed for use in applications up to 2.5Gb/s. The EM250-L3 transceivers provide the LC optical receptacle that is compatible with the industry standard LC connector. The transceiver also complies with the industry standard 2x5 footprint and meets the mezzanine height requirement of 9.8 mm. Each EM250L3 transceiver consists of an optical subassembly housing both the transmitter and the receiver, and an electrical subassembly. All are housed within a plastic/metal package.

The transmitter consists of a high-performance 850-nm VCSEL and the receiver consists of a GaAs PIN and a preamplifier.

All EM250-L3 transceivers also include a Signal Detect circuit that provides a TTL logic high output when a usable input optical signal level is detected.

Electromagnetic Interference (EMI)
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 EM250-L3 transceivers have been designed to perform to the specified limits. All transceivers comply with the FCC Class A limits.

Immunity
The EM250-L3 transceiver has been designed to provide good immunity to radio-frequency electromagnetic fields. Key components to achieve the good electromagnetic compliance (EMC) are the metal housing, and the chassis shield.

Eye Safety
The EM250-L3 850-nm VCSEL-based transceivers have been designed to meet Class 1 eye safety and comply with FDA 21 CFR 1040.10 and 1040.11 and the IEC 825-I.
