Cisco QSFP-100G-CWDM4-S Compatible QSFP28 100GBase-CWDM4 2KM 1270nm to 1330nm LC Connector SMF DOM MSA Compliant

• Product Overview

The 100GBASE-CWDM4 QSFP28 transceiver is a full duplex 100G QSFP28 optical transceiver that provides a high-speed link at aggregated data rate of 100 Gbps over 2 km on SMF. The transmitter path converts four lanes of serial electrical data to optical signal. The optical signals from the four lasers are optically multiplexed and coupled to single-mode fiber through an industry standard LC optical connector. The optical signals are engineered to meet the CWDM4 MSA specifications. On the receive side, the four incoming wavelengths are separated by an optical demultiplexer into four separated channels.100GBASE-CWDM4 QSFP28 Transceiver LC duplex 2km over 2 SMFs

For longer transmission distance, 100G QSFP28 CWDM4 is suggested, which supports a distance up to 2km over single-mode fiber optic cable. 100Gbase-CWDM4 standard is published by MSA, which is a more cost-effective solution for a wide range of applications compared with 100Gbase-LR4. This module uses CWDM technologies to transmit the 100G optical signal via a duplex LC interface over wavelengths near 1310nm.

CWDM4 modules comply with the requirements of this document and have the following common features:
four optical transmitters; four optical receivers with signal detect;
wavelength division multiplexer and demultiplexer;
Duplex optical connector for singlemode fiber. The optical connector type is vendor specific but can include SC or LC types.
