BlueOptics QSFP28 Transceiver BO28L13610D 100GBASE-LR4, LC-Duplex, Singlemode 4xWDM, 10 km, DDM/DOM, 0–70°C

The BlueOptics QSFP28 Transceiver BO28L13610D is a compatibility module designed for 100GBASE-LR4 links over singlemode fiber. In QSFP28 form factor it provides 100 Gbit/s throughput using four WDM lanes and an LC-duplex interface. The module supports digital diagnostic monitoring (DDM/DOM) and is specified to operate across an ambient temperature range of 0–70°C. It is intended for use in core aggregation points, data center uplinks and metro connections with reach up to 10 km over singlemode fiber.

Advantages

This transceiver offers a compact QSFP28 footprint that combines high-density port counts with 100G performance. The LC-duplex connector and 4xWDM design enable compatibility with standard singlemode cabling while keeping fiber routing simple. DDM/DOM support provides real-time monitoring of optical parameters such as transmit/receive power and temperature, which helps with diagnostics and link validation. The module’s operating temperature range and 10 km reach make it suitable for many enterprise and carrier metro deployments.

Suitable for

When it may not be suitable

This QSFP28 100GBASE-LR4 module is not appropriate for multimode fiber links or for singlemode links that require reaches significantly beyond 10 km. It is also not suitable where alternative connector types (for example, MPO/MTP) are mandated. Devices that do not accept QSFP28 form-factor transceivers or do not support 100GBASE-LR4 will be incompatible.

Key specifications

How to use

Install the transceiver into a compatible QSFP28 slot on a switch, router or media converter following the host device manufacturer’s insertion and handling procedures. Connect LC-duplex singlemode patch cables to the module ports, ensuring correct orientation of transmit and receive fibers and proper LC connector seating. After insertion, verify link status and use DDM/DOM telemetry via the host management interface to check optical parameters such as Tx/Rx power and temperature. For reliable operation, ensure fiber connectors are clean and adapters or patch panels are rated for singlemode use.

What to consider before purchase

Recommendations

Use singlemode LC-duplex patch cords of appropriate length and quality, maintain clean fiber endfaces, and verify DDM/DOM readings after installation to ensure expected signal levels and temperature conditions. Follow electrostatic discharge (ESD) precautions when handling the transceiver and store unused modules in protective packaging.
