Alcatel-Lucent 3HE00042AA SFP Transceiver Module

Alcatel-Lucent 3HE00042AA is a 622 Mbps SFP transceiver designed for OC-12/STM-4 SONET/SDH networks, delivering 1550 nm LR-2 operation over single‑mode fiber with an 80 km reach. This small form‑factor pluggable (SFP) module uses a duplex LC optical interface and supports Digital Diagnostics Monitoring (DDM/DOM) for real-time visibility into laser bias, supply voltage, temperature, and optical power. Intended for a 1-port OC-12/STM-4 link, the 3HE00042AA enables long‑haul connectivity over SMF, leveraging the 1550 nm window to minimize attenuation across long distances. Typical applications include telecom backbone links and enterprise WAN connections requiring reliable 622 Mbps transport.
