Product information

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

  • Interface type: QSFP
  • Maximum data transfer rate: 40000 Mbit/s
  • Operating wavelength: 850 nm
  • Applicable fibre type: multimode fiber (short reach)
  • Weight: 0.02 kg
  • Product colour: Silver

How to use

Install the BlueOptics QSFP transceiver into a compatible QSFP port on the network switch or server following the equipment manufacturer's handling guidelines. Ensure the device is powered down or that hot‑swap procedures are observed according to the host system documentation. Connect appropriate multimode fiber patch cords to the transceiver, confirm correct cable polarity and connector type, then power up and verify link status through the host device management interface. Use diagnostics available in the host system to monitor signal levels and link health.

Usage recommendations

Handle the transceiver using electrostatic discharge precautions and avoid touching optical interfaces. Store and transport in protective packaging to prevent contamination of the fibre connector. For reliable short‑reach performance, use multimode patch cords and adhere to multimode fibre specifications and connector cleanliness best practices.
