## Summary description

BlueOptics 40G-QSFP-LM4-BO is a QSFP fiber optic network transceiver module supporting up to 40,000 Mbit/s. Designed for high-speed links, it provides a QSFP interface in a QSFP form factor with silver housing and a 1,000,000 h MTBF. Suitable for data center uplinks, switch-to-switch connections and high-bandwidth aggregation.

## Long description

BlueOptics 40G-QSFP-LM4-BO is a QSFP fiber optic network transceiver module engineered for aggregated 40 Gbit/s links. The module provides a QSFP interface in a compact QSFP form factor and a silver metal housing. It is intended for high-speed data center uplinks, switch-to-switch connections and other aggregation points where a four-lane, 40,000 Mbit/s fiber connection is required. The specification includes support for multimode OM4 short-reach links and longer singlemode links through wavelength division, and a high MTBF rating for reliable operation.
Advantages
The BlueOptics 40G-QSFP-LM4-BO offers a four-lane 40G physical interface in a single QSFP package, enabling consolidation of multiple 10G lanes into a single port. Its metal silver housing provides mechanical robustness and thermal dissipation. With a compact QSFP form factor and an industry-standard QSFP interface, the module is compatible with a wide range of switches and aggregation equipment that accept QSFP transceivers. The specified maximum data transfer rate of 40000 Mbit/s and a long MTBF support continuous operation in rack and data center environments.
Suitable for (tasks / use cases)
 Data center uplinks requiring 40 Gbit/s aggregated bandwidth
 Switch-to-switch high-bandwidth connections in campus or enterprise networks
 High-density aggregation panels and spine-leaf architectures
 Short-reach multimode OM4 links and extended singlemode links where compatible
When it may not be suitable
This QSFP module is intended for fiber optic networks with QSFP ports and will not work in equipment that accepts only SFP, SFP+, or fixed optical ports without an appropriate adapter or breakout cable. It is not suitable for copper-only environments or for applications that require lower data rates where a simpler, lower-cost transceiver would suffice. Compatibility with specific switch models should be verified before purchase.
Key specifications
 Interface type: QSFP
 Maximum data transfer rate: 40000 Mbit/s
 Form factor: QSFP
 Housing: silver metal
 Weight: 0.04 kg
 Mean time between failures (MTBF): 1,000,000 hours (specified)
 Optical modalities: multimode OM4 (short reach) and singlemode compatibility via wavelength division
How to use
Insert the BlueOptics QSFP module into a compatible QSFP port on the switch or transceiver cage until it latches. Connect appropriate LC-Duplex or breakout fiber cables according to the intended link topology and fiber type (multimode OM4 for short-reach or singlemode fiber for extended reach). Ensure the host device power and port settings match the module’s operating requirements and enable the port in the switch configuration. Monitor link status and diagnostics via the host device; the module includes digital diagnostics monitoring (DDM) for optical parameter checks when supported by the equipment.
What to consider before purchase
 Verify that your switch or router supports QSFP transceivers and accepts 40G QSFP modules from third-party vendors.
 Confirm the required fiber type (multimode OM4 or singlemode) and maximum link distance for your application.
 Check port configuration and firmware compatibility on the host device to ensure proper recognition and operation.
 Ensure you have the correct fiber connectors and any needed breakout cables for 4x10G or LC-Duplex connections.
Usage recommendations
Use the BlueOptics 40G-QSFP-LM4-BO in well-managed rack environments with appropriate cooling. Deploy it for aggregation and uplink links where 40 Gbit/s capacity is required. Before large-scale rollouts, test the transceiver in a sample of your switching hardware to confirm compatibility and diagnostic reporting.
