Modulo transceiver in fibra ottica BlueOptics QLR4-PLUS-BO 40000 Mbit/s QSFP

The BlueOptics QLR4-PLUS-BO is a QSFP fiber optic transceiver module designed for high-speed network connections with a maximum data transfer rate of 40000 Mbit/s. It has a silver housing, weighs 20 g and conforms to CE, RoHS and FCC standards. The module follows QSFP interface conventions and is intended for single-mode fiber links using LC duplex connections and CWDM multiplexing where supported by the host equipment.

Advantages

This QSFP transceiver offers 40 Gbit/s line-rate capability in a compact QSFP form factor, enabling high-density port deployment. Compliance with CE, RoHS and FCC standards ensures regulatory conformity. The module’s lightweight metal housing supports integration into switches, routers and other networking hardware that accept QSFP optical modules. The design is compatible with industry MSA practices and includes support for optical signalling appropriate for long-reach single-mode links when used with matching fiber cabling and host software.

Key specifications

How to use

Insert the QSFP transceiver into a compatible QSFP slot on the host device following the manufacturer’s hot-plug procedures. Connect LC duplex single-mode fiber patch cords to the module’s transmit and receive ports, ensuring correct polarity. Verify that the host device supports the module’s operating mode and any required CWDM channels; enable or configure the interface in the device management plane. Monitor link status and alarms from the host to confirm proper initialization and sync at 40G.

Recommendations

Use high-quality single-mode LC duplex patch cords and appropriate patch panels to achieve optimal range and signal quality. Confirm host compatibility for digital diagnostic monitoring (DDM/DOM) and CWDM channel handling if remote diagnostics and wavelength multiplexing are required. Follow ESD precautions when handling the module and observe manufacturer guidance on insertion/removal to avoid damage.
