The Huawei QSFP-100G-CWDM4 is a QSFP28 transceiver designed for use with Singlemode fiber optics. It offers very high throughput, supporting up to 100 Gbps in accordance with the standard. It transmits over two optical fibers and features LC/UPC (duplex) connectors. Transmission is carried out using four wavelengths: 1271, 1291, 1311, and 1331 nm. The transmit power range is -6.5 ~ 2.5 dBm, and the receiver sensitivity is -9.8 dBm. The maximum transmission range is 2 km. The transceiver is designed to work with all Huawei solutions.
QSFP28 Transceiver
This device is a QSFP28 fiber optic transceiver that supports speeds of up to 100 Gbps. It is ideal for creating primary connections between different locations or devices within a single building. It offers significantly higher speeds compared to QSFP+ (40G) or SFP+ (10G) standards.


Singlemode Fiber, Range up to 2 km
The offered product is compatible with fiber optic cables equipped with Singlemode fiber, enabling a relatively long transmission range.
The QSFP-100G-CWDM4 transceiver features an optical power range of -6.5 ~ 2.5 dBm and a receiver sensitivity of -9.8 dBm. The maximum transmission range is 2 km, making the module suitable for connecting two moderately distant buildings.
LC/UPC Connectors
The transceiver uses standard LC/UPC connectors.


Two Connectors, Duplex Transceiver
The transceiver uses two connectors, one for transmitting (Tx) and the other for receiving (Rx) the signal. Four separate transmission channels operate at different wavelengths within the range of 1271 - 1331 nm. It is important to connect the Tx of one transceiver to the Rx of the other.
Compatibility
The transceiver is designed to work with all Huawei devices. It provides full support for all functions and operational status monitoring.
