Fiber optic transceiver BlueOptics VJW01 40000 Mbit/s QSFP 850 nm

The BlueOptics VJW01 40000 Mbit/s QSFP 850 nm is a fiber optic transceiver module designed for high-speed network connections. It supports up to 40 Gbit/s data transfer and uses a QSFP form factor with an 850 nm wavelength suitable for short-range multimode fiber links. Intended for installation in compatible network equipment, this module provides a compact optical interface for data center and enterprise networking environments.

Advantages

The transceiver offers a high maximum data transfer rate of 40000 Mbit/s in a QSFP package, enabling aggregation of multiple lanes or single-port 40 Gbit/s links. Operating at 850 nm, it is optimized for multimode fiber, allowing cost-effective short-reach connections. Its standard QSFP footprint ensures broad compatibility with switches and routers that accept QSFP optics, while the compact module size helps conserve port density in rack-mounted equipment.

Suitable for

• 40 Gbit/s uplinks between switches and aggregation points
• Short-reach connections in data centers using multimode fiber (MMF)
• High-bandwidth server-to-switch links within the same rack or adjacent racks
• Network equipment requiring QSFP-form-factor optical modules

Key specifications

• Form factor: QSFP
• Maximum data transfer rate: 40000 Mbit/s (40 Gbit/s)
• Operating wavelength: 850 nm
• Fiber type: multimode fiber (recommended for 850 nm operation)
• Application range: short-reach optical links (data center, enterprise)

How to use

Install the BlueOptics QSFP transceiver into a compatible QSFP port on a switch, router or network interface card following the equipment manufacturer's insertion and removal procedures. Connect the multimode fiber patch cable to the transceiver, ensuring correct connector type and polarity. After physical installation, verify the link status on the host device and configure port settings as required (link speed, duplex, and any relevant transceiver or optical settings). Monitor link alarms or errors to confirm proper operation.

Recommendations

Use high-quality multimode fiber and appropriate patch cords for 850 nm transmission, maintain clean connectors to prevent signal loss, and match the transceiver to equipment that supports QSFP optics and 40 Gbit/s links. For runs beyond the recommended short-reach range, consider alternative wavelengths or transceiver types designed for longer distances.
