QSFP transceiver modul BlueOptics QSFP-40G-LR4-VA-BO 40 Mbit/s

The BlueOptics QSFP-40G-LR4-VA-BO is a QSFP fiber optic transceiver module designed for single-mode fiber links with a maximum data rate of 40 Mbit/s. Housed in a durable metal casing and weighing 20 g, the module operates at 3.3 V and is intended for use as a hot-pluggable Ethernet or optical interconnect component in network hardware that supports QSFP interfaces. The transceiver is built to MSA-compatible mechanical and electrical specifications to ensure interoperability with systems that accept QSFP form-factor modules.

Advantages

This transceiver offers compatibility with QSFP-equipped switches, routers and storage systems while supporting single-mode LC duplex connections for bidirectional optical transmission. The metal housing and design-for-reliability deliver a high MTBF of 1,000,000 hours. The module supports standard optical monitoring functions where supported by host hardware, enabling remote diagnostics for voltage, laser bias, transmit/receive power and temperature.

Suitable for

• High-speed optical links between switches and routers over single-mode fiber
• Data center uplinks and aggregation links
• Long-distance fiber connections within campus or metro networks (single-mode)
• Systems requiring MSA-compliant QSFP pluggable modules

Key specifications

• Interface type: QSFP
• Maximum data transfer rate: 40 Mbit/s
• Connector type: LC Duplex (single-mode optical)
• Operating voltage: 3.3 V
• Housing: metal, hot-pluggable QSFP form factor
• Weight: 0.02 kg
• Mean time between failures (MTBF): 1,000,000 hours

How to use

Install the module into a compatible QSFP slot on supporting network equipment while the host device is powered on or following the manufacturer's hot-swap guidance. Connect single-mode LC duplex fiber patch cords to the module's LC ports, observing proper transmit (TX) to receive (RX) polarity. Verify that the host system recognizes the module and that any required firmware or software settings permit use of third-party QSFP transceivers. If the host supports digital diagnostics (DDM/DOM), enable and monitor the diagnostic parameters to confirm proper operation.

Recommendations

Use high-quality single-mode fiber patch cords and maintain clean connector endfaces to achieve the specified range and signal quality. Confirm host compatibility for third-party QSFP modules before deployment, and monitor DDM/DOM parameters where available to detect degradation in optical power or temperature. Handle the transceiver by its edges, avoid touching optical interfaces, and store with dust caps when not in use.
