QSFP+ CWDM OPTEC 40G SM LC 7.5dB 20km DFB/PIN TX1271-1331 DDM

QSFP+ 40G LR4 transceivers are high-performance optical modules designed for data transmission at speeds of up to 40 Gb/s over long distances using single-mode fiber (SMF). These transceivers are used in data centers, enterprise networks, carrier infrastructure, and Internet Service Provider (ISP) networks.

CWDM (Coarse Wavelength Division Multiplexing) technology enables the transmission of four independent optical channels, each with a bandwidth of 10 Gb/s, over a single pair of optical fibers. The individual channels use wavelengths of 1271 nm, 1291 nm, 1311 nm, and 1331 nm, while the connection is made using a standard Duplex LC connector. This solution reduces the number of fibers required in the infrastructure and provides greater installation flexibility compared with solutions using multimode fiber and MPO/MTP connectors.

Key features:

• QSFP+ form factor
• Data rate of up to 40 Gb/s, 4× 10 Gb/s
• Single-mode fiber (SMF)
• Duplex LC connector
• CWDM transmission technology
• Wavelengths: 1271 nm, 1291 nm, 1311 nm, 1331 nm
• DDM/DOM: digital monitoring of module operating parameters, including temperature, voltage, and optical transmit and receive power
• Hot-Pluggable: enables the transceiver to be installed or replaced without powering down the network device
• Applications: data transmission in 40GbE Ethernet networks and telecommunications and carrier infrastructure.
