## Long description

BlueOptics QSFP-40G-LM4-BO is a metal-housed QSFP fiber optic transceiver module that supports a 40 Mbit/s data rate and uses an LC Duplex connector. It implements the 40GBASE-LX4 optical standard with CWDM transmit and receive channels and is designed for use in high-density switches, routers and other network equipment that accept QSFP 40GBASE-LX4 optics. The module supports both multimode and single-mode fiber links and includes Digital Diagnostics Monitoring (DDM/DOM) for real-time status of supply voltage, laser bias current, optical output and input power, and temperature.
Advantages
The module is manufactured to MSA QSFP standards and is tested for compatibility with major Dell platforms. It uses high-quality components from established suppliers, offers an MTBF around 1,000,000 hours and a projected lifecycle of approximately 10 years, and supports Ethernet, FCoE or SDH/SONET applications at up to 40 Gbit/s over distances up to 2 km. DDM simplifies monitoring and maintenance of optical links.
Suitable for
40G fiber uplinks in data centre switches and aggregation equipment
High-density routers and storage system interconnects
Networks requiring QSFP 40GBASE-LX4 optics with LC Duplex connections
When it may not be suitable
This transceiver is not suitable for hardware that does not support QSFP 40GBASE-LX4 modules or for applications that require speeds other than up to 40 Gbit/s. It also requires compatible DDM/DOM support in the host device to use the diagnostic features.
Key specifications
Interface type: QSFP with LC Duplex connector
Optical standard: 40GBASE-LX4 with 4x CWDM lanes
Supported media: Multimode (e.g., OM4) and Single-mode fiber
Maximum data transfer rate: 40 Mbit/s (module rated for 40G operation)
Typical reach: up to 160 m on multimode (OM4) and up to 2 km on single-mode
Operating temperature range: 0°C to +70°C
Digital Diagnostics: DDM/DOM (MSA SFF-8472 compliant)
MTBF: ~1,000,000 hours
Weight: 0.04 kg
How to use
Install the QSFP module into a compatible QSFP slot on your switch, router or storage device following the host vendor’s instructions. Connect fibers using LC Duplex patch cords and ensure correct polarity. Verify that the host device supports 40GBASE-LX4 and DDM/DOM if diagnostics are required. After insertion, check link status and diagnostic values in the host management interface.
What to consider before purchase
Confirm your hardware supports QSFP 40GBASE-LX4 modules and LC Duplex connectors
Verify required reach (multimode OM4 ~160 m vs single-mode up to 2 km)
Check that the host device supports DDM/DOM if you need real-time diagnostics
Ensure the product’s operating temperature range fits your environment
Usage recommendations
Use factory-tested LC Duplex fiber patch cords and, where possible, connect via a patch panel to maintain optimal optical performance. Request a sample to validate compatibility with your specific Dell platform before large deployments.
