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.

Digital Diagnostics Monitoring (DDM):
Yes
Fiber ethernet cabling technology:
40GBASE
Rx wavelength (max):
850 nm
Tx wavelength (max):
850 nm
Wavelength: The distance over which a wave repeats itself. The wavelength determines the characteristics of the wave e.g. red light has a different wavelength to blue light.
850 nm
Maximum transfer distance: The greatest distance over which the data/signal can be transferred.
150 m
SFP transceiver standard:
SR4
Fiber optic connector: This terminates the end of an optical fiber, and enables quicker connection and disconnection than splicing. The connectors mechanically couple and align the cores of fibers so light can pass. Better connectors lose very little light due to reflection or misalignment of the fibers. In all there have been about 100 types of optic fiber connectors produced.
