## Summary description

The BlueOptics WSP-Q40GLR4L-BO is a fiber optic transceiver module designed for high-speed data transfer up to 40000 Mbit/s. It features a QSFP interface and is compatible with Cisco products. The module is RoHS compliant and weighs 40 g, making it a reliable choice for network applications.

## Long description

The BlueOptics WSP-Q40GLR4L-BO fiber optic transceiver module is a QSFP form-factor device designed for high-speed optical links up to 40,000 Mbit/s (40 Gbit/s). It implements 40GBASE-LR4L-style single-mode transmission with LC duplex connectivity and is engineered to be compatible with major Cisco platforms that support the corresponding QSFP modules. The module is RoHS compliant, has a silver housing, and a lightweight construction of approximately 0.04 kg suitable for dense network installations.
Advantages
The module supports full-duplex optical transmission using CWDM-enabled transmitter and receiver components, enabling 40 Gbit/s transport over single‑mode fiber. It follows MSA-defined QSFP mechanical and electrical interfaces to ensure interoperability with MSA-compliant hardware. Built with diagnostic capability, the transceiver provides real-time monitoring of operating parameters when the host system supports DDM/DOM. The compact QSFP form factor and low weight make it suitable for space-constrained switch and router ports.
Suitable for
40G Ethernet uplinks and aggregation links in data center and campus networks
Fibre Channel over Ethernet (FCoE) and SDH/SONET applications requiring 40 Gbit/s optical links
Interconnects between switches, routers, storage systems, and optical patch panels over single-mode fiber
Key specifications
Interface type: QSFP (quad small form-factor pluggable)
Maximum data transfer rate: 40,000 Mbit/s (40 Gbit/s)
Connector type: LC duplex (single-mode fiber)
Transmission: 40GBASE-LR4L style, CWDM-enabled transmit and receive
Compliance: RoHS; MSA QSFP mechanical/electrical interoperability
Module colour: Silver
Weight: approx. 0.04 kg
How to use
Insert the QSFP transceiver into a compatible QSFP port on a switch, router, or storage device following the host vendor's hot‑plug instructions. Connect LC duplex single‑mode fiber patch cables to the module's transmit and receive ports, ensuring correct polarity. If the host device supports digital diagnostics (DDM/DOM), enable or query the monitoring interface to view supply voltage, laser bias current, optical output and input power, and module temperature for operational insight. Verify link status and negotiate the appropriate protocol (Ethernet, FCoE, SDH/SONET) on both ends of the link.
Usage recommendations
Use factory-tested single‑mode LC patch cords and, where possible, route fibers through protected patch panels to preserve connector integrity and optical performance. Confirm software or firmware compatibility with the host platform to ensure proper recognition and full functionality of the transceiver and diagnostic features.
