Overview:
The LINK-PP LS-SM3110-20C is a high-performance, hot-pluggable 10G SFP+ optical transceiver module designed for reliable long-reach data transmission over single-mode fiber (SMF). Operating at a 1310nm center wavelength, this module supports data rates from 1.0Gbps to 10.7Gbps, making it suitable for 10GBASE-LR and 10GBASE-LW applications.
Built with a 1310nm DFB laser transmitter and a PIN photodiode receiver, the LS-SM3110-20C delivers stable optical performance, excellent
link budget, and robust compatibility with modern networking
systems. With a transmission distance of up to 20km over SMF and a standard Duplex LC receptacle, it is an ideal choice for enterprise networks, telecom
infrastructure, switches, routers, and optical transport equipment.
This model also supports Digital Diagnostic Monitoring (DDM/DOM), allowing real-time access to key module parameters such as
temperature, voltage, TX bias current, and optical power levels
through the I2C interface.
