## Long description

The BlueOptics BN-CKM-QP-SR4 is a QSFP fiber optic transceiver module engineered for 40 Gbit/s high‑speed data links. Operating at a wavelength of 850 nm, this compact module supports short‑reach multimode fiber connections and is intended for data centre and enterprise network environments that require reliable, high‑capacity transmission in a small form factor. The module is lightweight (20 g) and finished in silver, making it easy to handle and install in compatible QSFP ports.
Advantages
The module delivers a maximum data transfer rate of 40000 Mbit/s and complies with standard QSFP interfaces to ensure interoperability with a range of network equipment. Its 850 nm optical wavelength is suited for multimode fiber applications, and the compact QSFP package provides four‑lane channels in a single connector to support aggregated high throughput. Low weight and a standardized form factor simplify deployment and replacement in rack systems and switches.
Suitable for
 Short‑reach multimode fiber links within data centres
 40 Gbit/s uplinks between aggregation switches
 High‑throughput server connections and storage networks
 Network equipment requiring a QSFP optical module
Key specifications
