ADVA SFP/GBE/850I/MM/LC SFP Optical Transceiver

The ADVA SFP/GBE/850I/MM/LC is a small form-factor pluggable (SFP) optical transceiver module designed for Gigabit Ethernet applications over multimode fiber infrastructure. Operating at a wavelength of 850 nm, the module supports data transmission at 1 Gbit/s and complies with the IEEE 802.3z 1000BASE-SX standard for short-reach optical connectivity. The transceiver features a duplex LC connector interface, ensuring compatibility with standard structured cabling systems deployed in enterprise data centers, campus networks, and telecommunications facilities. The "I" designation indicates industrial temperature range operation, providing reliable performance in demanding environmental conditions from -40°C to +85°C. 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, supporting transmission distances up to 550 meters on OM2 multimode fiber and extended reach on OM3/OM4 fiber types. It is designed for deployment in ADVA optical transport platforms and compatible third-party switches, routers, and media converters 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 horizontal cabling, inter-switch links, server connectivity, and storage network applications requiring cost-effective short-distance optical transmission.
