QSFP112 FR4 OPTEC 400G SM LC 4dB (2km) TX1271-1331 DDM

QSFP112 400G FR4 transceivers are modern optical modules designed for ultra-high-speed connections in high-bandwidth networks. They enable data transmission at speeds of up to 400 Gb/s, meeting the growing demands of modern network infrastructures.

These modules use PAM4 technology (4×100G), allowing efficient transmission of large amounts of data with a limited number of optical channels. The FR4 standard is based on four wavelength transmission, enabling connections over single-mode fiber (SMF), compliant with the IEEE 802.3cu standard.

The transceivers are equipped with an LC Duplex connector, allowing them to operate within widely used fiber optic infrastructure. Their compact form factor supports high port density in networking devices, which is essential in modern large-scale environments.

Built-in features such as DDM (Digital Diagnostic Monitoring) allow real-time monitoring of module operating parameters. With hot-plug support, the modules can be installed or replaced without interrupting device operation.

Key features:

• Data rate up to 425 Gb/s

• Built-in 400G PAM4 DSP

• 4 CWDM channels (EML) + PIN receiver (4 channels)

• Maximum reach up to 2 km

• LC Duplex connector

• DDM function - real-time monitoring

• Hot-pluggable

• Low power consumption (<10 W)

• Operating temperature: 0-70°C

• RoHS compliant.
