Transceiver BlueOptics QSFP28 BO28L13910D 4x25G LR

BlueOptics QSFP28 BO28L13910D is a QSFP28 LR optical transceiver designed to deliver 4×25G lanes for 100G links over long-reach single-mode fiber. The module is intended for use in high-capacity network environments such as data centers, aggregation switches and routers that provide QSFP28 ports. It offers an interoperable form factor for simplifying upgrades to 100G connectivity while minimizing the need for additional cabling.

Advantages

This QSFP28 LR transceiver supports four independent 25G channels to carry a combined 100G signal, enabling high-throughput connections over single-mode fiber at extended distances. The compact QSFP28 form factor reduces occupied port density while maintaining compatibility with standard QSFP28 slots. Its long-reach optical design is suitable for connections between racks, aggregation layers and campus links where single-mode fiber is deployed.

Suitable for

• 100G uplinks between switches and aggregation devices
• Long-reach single-mode fiber connections in data centers
• High-bandwidth links for routers, core switches and optical transport
• Network upgrades where QSFP28 ports are available

Key specifications

• Interface: QSFP28 form factor with 4 transmit and 4 receive lanes
• Data rate: 4 × 25 Gbit/s (aggregate 100 Gbit/s)
• Optical reach: long-reach single-mode fiber suitable for extended distances
• Wavelength: single-mode optical wavelength per lane (standards-compliant)
• Connector type: LC duplex (single-mode)
• Power consumption: typical low-power QSFP28 profile (device-dependent)
• Hot-pluggable design for easy installation and replacement

How to use

Install the transceiver into an available QSFP28 port on a compatible switch or router; ensure the host device supports QSFP28 LR modules. Connect single-mode LC duplex fiber patch cords to the module’s transmit and receive ports, observing correct polarity. After insertion and fiber connection, verify link status and configure interface settings on the host device as required for 25G lanes or 100G operation. Follow your equipment vendor’s guidance for enabling and monitoring the optical interface.

Usage recommendations

Handle the transceiver with static-safe precautions and keep dust caps on connectors when not in use. Verify compatibility with your network equipment and consult fiber link budget calculations for reliable long-reach performance. Use certified single-mode LC fiber patch cords and maintain proper polarity and cleanliness to ensure stable 100G links.
