D-LINK 1000Base-LX SFP SINGLE MODE TRANSCEIVER
DEM-310GT SFP transceiver is a 1Gbps, hot-pluggable SFP module designed for single-mode and multi-mode fiber networks. It features a duplex LC connector and supports a wavelength of 1310 nm, providing reliable long-distance connectivity up to 10 km on single-mode fiber. This 1000BASE-LX compliant SFP delivers TX optical power up to -3 dBm, RX sensitivity down to -21 dBm, and a power budget between 11.5–18 dB, ensuring high-performance fiber links.
The metallic housing ensures durability and heat dissipation, while 3.3V low-power operation and hot-pluggable design allow easy deployment in enterprise networks, data centers, and fiber channel SANs. Fully RoHS and MSA compliant, the DEM-310GT meets EMI and safety certifications including FCC Class B, CE Class B, ICES-003 Class B, VCCI Class B, FDA/CDRH, TUV, and cUL.
Applications: Ideal for Gigabit Ethernet networks, IP backbone connections, enterprise fiber networks, and storage area networks (SANs) requiring 1Gbps SFP modules.
