BlueOptics QSFP Transceiver 02313URS-BO 40GBASE-LR4L LC-Duplex Singlemode 4xWDM 2 km DDM/DOM

BlueOptics QSFP Transceiver 02313URS-BO is a compatible 40GBASE-LR4L optical module designed for use in QSFP ports of switches and routers. The module uses LC-duplex connectors over singlemode fiber and implements four WDM channels to carry 40 Gbit/s aggregated throughput across distances up to 2 km. It includes DDM/DOM support for real-time diagnostic monitoring and is specified to operate in environments from 0°C to +70°C.

Advantages

This BlueOptics QSFP transceiver provides a cost-effective compatible option for deploying 40GBASE-LR4L links on singlemode fiber with LC-duplex connectivity. The 4xWDM implementation enables high-density aggregation within a single QSFP housing while keeping fiber pair count low. Built-in DDM/DOM offers operational visibility for parameters such as optical power and temperature, easing troubleshooting and maintenance. The module's specified operating temperature range and industry-standard QSFP form factor make it suitable for typical data center and network edge equipment.

Suitable for

• 40 Gbit/s optical uplinks between switches and routers over singlemode fiber
• Short-distance metro or campus links up to 2 km
• High-density aggregation using QSFP ports where LC-duplex terminations are used
• Environments requiring optical diagnostics via DDM/DOM

When it may not be suitable

This transceiver is not suitable for multimode fiber installations because it is designed for singlemode fiber and 40GBASE-LR4L operation. It is also not intended for links that require distances beyond 2 km; for longer spans, modules specified for longer reach should be selected. Compatibility cannot be guaranteed with every vendor device despite being a compatible module, so verification of host equipment support for third-party transceivers is recommended.

Key specifications

• Data rate: 40 Gbit/s (LR4L)
• Interface: LC duplex
• Fiber type: Singlemode
• WDM configuration: 4xWDM
• Maximum link distance: up to 2 km on singlemode fiber
• Diagnostics: DDM/DOM support
• Operating temperature: 0°C to +70°C
• Form factor: QSFP

How to use

Install the QSFP transceiver into a compatible QSFP port following the host device manufacturer's insertion procedure to avoid electrostatic discharge and mechanical damage. Connect LC-duplex singlemode patch cables to the module ensuring correct transmit/receive orientation. After link establishment, monitor DDM/DOM parameters via the host management interface to confirm optical power levels and module temperature are within expected ranges. To remove the module, follow the device-specific safe removal steps while the port is administratively disabled if required.

What to consider before purchase

• Confirm the host switch or router supports compatible (third-party) QSFP transceivers
• Ensure singlemode LC-duplex fiber infrastructure is in place and supports the required 2 km span
• Verify link budget and optical power requirements for the specific fiber plant and connectors
• Check that the operating temperature range suits the installation environment

Usage recommendations

Use proper singlemode LC-duplex patch cords and maintain clean connector endfaces. Monitor DDM/DOM values after commissioning to detect early signs of connector loss or fiber degradation. For interoperability, test the module in a non-critical link before wide deployment.
