## Long description

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.
Suitable for
 40G Ethernet uplinks and aggregation ports
 High-speed connections between switches, routers and storage systems
 Data center interconnects over single-mode fiber
 Long-reach optical links requiring CWDM support
Key specifications
 Form factor: QSFP
 Maximum data transfer rate: 40000 Mbit/s
 Connector type: LC duplex (optical)
 Fiber type: Single-mode (SMF), CWDM-capable
 Typical operational range: long-reach class (up to multiple kilometers depending on link design and fiber)
 Product colour: Silver
 Weight: 0.02 kg
 Regulatory compliance: CE, RoHS, FCC
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.
Usage 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.
