The AddOn Networks 3CSFP91-AO is an HP and 3Com compatible SFP optical transceiver module designed for 1000Base-SX Gigabit Ethernet over multi-mode fiber. It operates at 850nm wavelength with a VCSEL laser transmitter and PIN photodiode receiver, supporting data rates from 1.063 to 1.25 Gbps. Maximum reach is 550m over 50/125μm MMF or 220m over 62.5/125μm MMF, with dual LC/UPC connectors and hot-pluggable SFP form factor. It guarantees a 7.5 dB link budget and complies with IEEE 802.3z, SFP MSA, and INF-8074i standards. Power consumption is low at 90-130 mA transmit and 80-110 mA receive on +3.3V supply. Operating temperature ranges from 0 to 70°C standard, with industrial options to -40 to 85°C. TAA compliant, RoHS certified, and made in USA/UK, it suits enterprise data centers, campus networks, and storage connectivity requiring reliable 1G fiber links.
