Alcatel-Lucent 3HE00027AA 01 100BASE-SX SFP Optical Transceiver

The Alcatel-Lucent 3HE00027AA 01 is a small form-factor pluggable (SFP) optical transceiver module designed for Fast Ethernet applications over multimode fiber infrastructure. Operating at a wavelength of 850 nm, the module supports data transmission at 100 Mbit/s and complies with IEEE 802.3u 100BASE-SX standard for short-reach optical connectivity in enterprise and carrier networks. The transceiver features a duplex LC connector interface, ensuring compatibility with standard structured cabling systems deployed in telecommunications facilities and data centers. The module incorporates digital diagnostic monitoring (DDM) capabilities per SFF-8472 specification, enabling real-time access to operational parameters including temperature, laser bias current, transmitted optical power, received optical power, and supply voltage. Hot-pluggable design allows for non-disruptive replacement and maintenance in live network environments without powering down host equipment. The transceiver utilizes VCSEL (Vertical-Cavity Surface-Emitting Laser) technology for efficient optical signal generation over multimode fiber with typical reach up to 2 kilometers on OM1 fiber and extended distances on higher-grade OM2/OM3 fiber types. It is designed for deployment in Alcatel-Lucent optical transport platforms and compatible third-party switches and routers supporting SFP MSA-compliant slots. Management and provisioning are performed through a two-wire serial interface (I2C), ensuring seamless integration with network management systems. This module is suitable for metropolitan area networks, enterprise campus backbones, and fiber-to-the-building applications requiring cost-effective short-to-medium distance optical transmission at Fast Ethernet speeds.
