## Long description

The BlueOptics QSFP-40G-SR4-NK-BO is a QSFP fiber optic transceiver module designed for 40 Mbit/s data transfer over an 850 nm wavelength. Housed in metal and weighing 20 g, the module is intended for short-reach multimode fiber links where a compact, hot-pluggable QSFP interface is required. The transceiver provides a balanced receiver and transmitter at 850 nm and is built to deliver long operational life with a stated mean time between failures (MTBF) of 1,000,000 hours.
Advantages
The module offers a QSFP interface in a metal housing that supports reliable insertion and operation in compatible network equipment. Its lightweight design and compact form factor make it suitable for dense installations. The specified MTBF indicates a design focus on operational longevity and reduced maintenance cycles. Support for 850 nm multimode optics aligns the module with common short-range data center and network interconnect scenarios.
Suitable for
Short-reach multimode fiber connections in data centers
40 Mbit/s high-speed links between switches, routers and storage systems
Environments requiring compact, hot-pluggable QSFP transceivers
Key specifications
Interface type: QSFP
Maximum data transfer rate: 40 Mbit/s
Wavelength: 850 nm
Housing: metal
Weight: 0.02 kg
MTBF: 1,000,000 hours
How to use
Install the transceiver into a compatible QSFP port on network equipment while the device is powered on or according to the host system instructions for hot-pluggable modules. Connect the MPO/MTP multimode fiber cable to the transceiver ensuring correct polarity and secure connection. Verify link status and data rate on the host system; ensure the connected hardware supports 40 Mbit/s operation and 850 nm multimode optics. Follow any platform-specific procedures for enabling digital diagnostics or monitoring features if supported.
Usage recommendations
Use certified multimode MPO/MTP patch cords and maintain fiber connectors clean and undamaged. Confirm host compatibility and firmware support for third-party QSFP modules and enable any available digital diagnostic monitoring (DDM/DOM) on supported platforms to monitor optical power and temperature for preventive maintenance.
