ADVA SFP/2Q1/8501/MM/LC SFP Optical Transceiver

The ADVA SFP/2Q1/8501/MM/LC is a small form-factor pluggable (SFP) optical transceiver module designed for short-reach multimode fiber applications in Gigabit Ethernet and Fibre Channel networks. Operating at a wavelength of 850 nm, the module supports data transmission over multimode fiber with typical reach up to 550 meters on OM2 fiber and extended distances on OM3/OM4 fiber types. The transceiver features a duplex LC connector interface, ensuring compatibility with standard structured cabling systems deployed in enterprise data centers and telecommunications facilities. It complies with IEEE 802.3z 1000BASE-SX and SFF-8472 industry standards, incorporating digital diagnostic monitoring (DDM) capabilities for real-time access to operational parameters including temperature, laser bias current, transmitted and received optical power, and supply voltage. The module is hot-pluggable and designed for deployment in ADVA optical transport equipment and compatible third-party switches and routers supporting SFP MSA-compliant slots. It operates within a commercial temperature range and maintains low power consumption suitable for high-density port configurations. The transceiver utilizes VCSEL (Vertical-Cavity Surface-Emitting Laser) technology for reliable optical signal generation and includes integrated signal conditioning circuits for optimal data integrity. Management and provisioning are performed through a two-wire serial interface (I2C), enabling seamless integration with network management systems. This module is suitable for intra-data center connectivity, horizontal campus cabling, and short-reach inter-switch links requiring cost-effective optical connectivity.
