BlueOptics QSFP28 Transceiver X50210A-BO, 100GBASE-DR, LC-Duplex, Singlemode 1310nm, PAM4, 500m, DDM/DOM

BlueOptics QSFP28 Transceiver X50210A-BO is a compatible 100GBASE-DR optical module that provides high-speed singlemode fiber connectivity over LC-duplex connectors. Operating at 1310 nm with PAM4 modulation, this QSFP28 transceiver supports links up to 500 meters and includes digital diagnostics (DDM/DOM) for real-time monitoring of optical parameters. The module is specified for an operating temperature range of 0°C to +70°C and is intended for use in dense data center uplinks, campus backbones and other high-capacity network segments where 100 Gbit/s singlemode links are required.

Advantages

The BlueOptics QSFP28 X50210A-BO delivers 100 Gbit/s throughput using PAM4 modulation while remaining compatible with standard QSFP28 ports and LC-duplex singlemode fiber. Built-in DDM/DOM enables monitoring of transmit and receive power, temperature and supply voltage to help maintain link reliability and simplify troubleshooting. Its 500 m reach at 1310 nm covers typical short-reach singlemode applications in data centers and campus environments, and the industrial operating range supports rack and enclosure installations within the specified temperature limits.

Suitable for

• Data center top-of-rack and spine-to-spine 100G uplinks
• Campus backbone and aggregation links requiring 100G singlemode connections
• High-performance computing interconnects and optical switching fabric
• Network refreshes where QSFP28 form-factor compatibility is required

When it may not be suitable

This transceiver is designed for singlemode fiber and LC-duplex connectors; it is not suitable for multimode fiber environments or applications requiring MPO/MTP connectivity. Links longer than 500 meters or systems that require wavelengths other than 1310 nm will need a different transceiver. Also, it is a QSFP28 module that requires a compatible 100G-capable port—older 10G/25G-only ports are not supported.

How to use

Install the BlueOptics QSFP28 X50210A-BO into a compatible QSFP28 port on your switch or router, ensuring the module is fully seated and the retention latch is engaged. Connect LC-duplex singlemode patch cables with correct polarity to the remote transceiver. Verify that the host device recognizes the module and that link parameters such as speed and lane configuration are set to support 100G PAM4 operation. Use management tools or the module’s DDM/DOM features to monitor optical power, temperature and voltage after bringing the link up. Follow the host vendor’s hot-swap and ESD handling guidelines during installation and removal.

What to consider before purchase

• Confirm your switch or router has QSFP28 ports and supports 100G PAM4 modules
• Verify singlemode LC-duplex cabling and correct polarity are available for the link
• Ensure required link distance does not exceed 500 meters
• Check operating temperature requirements for your deployment environment

Usage recommendations

For reliable performance, use factory-tested singlemode LC patch cables, enable DDM/DOM monitoring to track link health, and ensure firmware or driver compatibility on the host device. Avoid exceeding the specified temperature and distance limits and follow standard ESD precautions when handling the module.
