## Summary description

BlueOptics PAN-QSFP-40GBASE-LM4-BO is a QSFP fiber optic transceiver supporting up to 40,000 Mbit/s. Housed in metal with a silver finish, it provides a QSFP interface for 40 Gigabit Ethernet links. Designed for high-speed network uplinks and data center interconnects where multi-channel 40G connectivity is required.

## Long description

BlueOptics PAN-QSFP-40GBASE-LM4-BO is a QSFP fiber-optic transceiver module designed for 40 Gbit/s links. The module uses an LC duplex connector and supports 40GBASE-LX4 operation with four CWDM lanes, enabling multimode OM4 links up to 160 meters and single-mode fiber links up to approximately 2 kilometers. Housed in a metal case with a silver finish, this QSFP transceiver is intended for high-speed uplinks, data centre interconnects and other network hardware that accept QSFP 40G modules.
Advantages
The transceiver supports up to 40,000 Mbit/s and implements digital diagnostics (DDM/DOM) for real-time monitoring of supply voltage, laser bias current, transmit power, receive power and temperature. It is manufactured to MSA compatibility and is tested for interoperability with systems that accept the equivalent 40GBASE-LX4 QSFP modules. Constructed with industry-grade components and a durable metal housing, it is intended for long operating life and high availability in high-speed networks.
Suitable for
40 Gigabit Ethernet uplinks and switches
Data centre interconnects and aggregation links
High-speed storage network links and routers
Environments requiring QSFP form-factor transceivers with LC duplex connections
When it may not be suitable
This QSFP module uses the 40GBASE-LX4 specification and CWDM lanes; it is not suitable where a different optical standard (for example 10G-only SFP+ or other QSFP variants such as QSFP28 for 100G) is required. The stated reach differs between multimode and single-mode fiber—for distances beyond the specified single-mode range, a different module or amplifier may be needed.
Key specifications
Interface type: QSFP (Quad Small Form-factor Pluggable)
Data rate: up to 40,000 Mbit/s (40 Gbit/s)
Standard: 40GBASE-LX4 (4× CWDM lanes)
Connector: LC duplex
Multimode OM4 reach: up to ~160 m
Single-mode fiber reach: up to ~2 km
Operating temperature range: 0°C to +70°C
Housing: metal, silver colour
Monitoring: DDM/DOM (MSA SFF-8472 compliant)
Weight: approx. 0.04 kg
How to use
Insert the QSFP module into a compatible QSFP port on a switch, router or other network device while the device is powered per the vendor’s instructions. Connect LC duplex patch cords to the module—observe correct transmit/receive orientation and use appropriate multimode or single-mode cable according to the link plan. If DDM/DOM monitoring is required, enable or verify support for diagnostics on the host device to read real-time parameters for maintenance and troubleshooting.
What to consider before purchase
Verify that your hardware explicitly supports QSFP 40GBASE-LX4 modules or compatible third-party QSFP transceivers.
Confirm required link distance and choose multimode OM4 or single-mode fiber accordingly.
Ensure the host device supports DDM/DOM if remote diagnostic monitoring is needed.
Check operating temperature range and environmental requirements for your installation site.
Usage recommendations
Use certified LC duplex fibre patch cords and, where possible, patch panels to achieve optimal link quality. Test the module in your environment before large-scale deployment to confirm compatibility and performance.
