Alcatel 3HE07158BA Optical Transceiver for 7750 SR-12 IMM-2PCA-FP3

The Alcatel 3HE07158BA is a high‑performance optical transceiver module designed for use with the 7750 SR‑12 IMM‑2PCA‑FP3 interface card. This SFP+ (Small Form‑factor Pluggable) transceiver provides a flexible and hot‑swappable optical interface for Gigabit or 10 Gigabit Ethernet connectivity, enabling high‑speed fiber links in carrier‑grade IP/MPLS networks.

Overview

The 3HE07158BA transceiver is part of Alcatel’s optical module portfolio, supporting a variety of reach and wavelength options. It typically operates at 10 Gbps over single‑mode fiber for distances up to 10 km or more, depending on the specific variant. The module conforms to MSA (Multi‑Source Agreement) standards, ensuring interoperability with other compliant equipment. It features digital diagnostics monitoring (DDM) for real‑time reporting of optical power, temperature, voltage, and laser bias current.
