40G QSFP+ OPTEC PLR4 SMF 1x MPO 20km Tx:4x 1310nm/Rx:4x 1310nm DDM (QSFP-40G-PLRL4)

QSFP+ 40G PLR4 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.

Parallel transmission technology (Parallel SMF / PSM4) uses four independent optical channels, each with a bandwidth of 10 Gb/s, operating at a single wavelength of 1310 nm. The connection is established using a multi-fiber MPO/MTP connector (8 SMF fibers: 4 for transmission and 4 for reception). The main advantage of the PLR4 architecture is the ability to flexibly split a single 40G port into four independent 10GBASE-LR connections using an MPO-4xLC cable, making these modules an ideal solution for flexibly connecting devices with different port densities.

Key features:

• QSFP+ form factor
• Data rate up to 40 Gb/s, 4× 10 Gb/s, 4× 10 Gb/s
• Single-mode fiber (SMF)
• MPO/MTP connector (8 fibers)
• Parallel transmission technology (Parallel SMF/PSM4)
• Wavelengths: 4× 1310 nm
• Direct breakout to 4× 10GBASE-LR
• DDM/DOM: digital monitoring of module operating parameters, including temperature, voltage, and transmitter/receiver optical power
• Hot-Pluggable: allows the transceiver to be installed or replaced without powering down the network device
• Applications: data transmission in 40GbE Ethernet networks, direct Switch-to-Switch connections, and 40G-to-4×10G port breakout in data center and carrier infrastructure.
