## Long description

The Transceiver CBO QSFP28-100G-LR4 100G LR4 fiber optic module by BlueOptics is a QSFP28 form-factor 100 Gigabit LR4 transceiver designed for long-reach single-mode fiber connections. It supports 100G data transmission using LR4 wavelengths and is intended for deployment in data center interconnects, core and aggregation layers, and telecom links where long-distance optical connectivity is required. The module provides a compact solution for high-speed uplinks and network expansion over single-mode fiber.
Advantages
The BlueOptics QSFP28 LR4 module offers high-density 100 Gigabit connectivity in a small QSFP28 form factor, enabling efficient use of rack and switch ports. It supports long-reach single-mode links with LR4 wavelength multiplexing to maintain signal integrity over extended distances. The module is interoperable with standard QSFP28 ports and is suitable for scalable network upgrades without changing existing fiber infrastructure.
Suitable for
Data center interconnect (DCI) links requiring 100G long-reach single-mode connectivity
Core and aggregation network uplinks in enterprise and service provider environments
Telecom and metro links where LR4 wavelengths are used for long-distance optical transport
High-speed uplinks between switches, routers, and optical transport equipment
Key specifications
Form factor: QSFP28
Data rate: 100 Gigabit Ethernet
Fiber type: Single-mode fiber (SMF)
Transmission type: LR4 wavelength division multiplexing for long-reach links
Typical application: Long-reach optical links and data center interconnects
Connector interface: Duplex LC (or QSFP28 common optical interface for LR4 modules)
How to use
Install the transceiver into a compatible QSFP28 port on a switch, router, or optical transport device, ensuring the device supports 100G LR4 modules. Connect single-mode fiber using the appropriate LC duplex patch cords and verify polarity and connector cleanliness before insertion. After physical installation, check the device interface status and configure the network port as required by your equipment and network design. Monitor link status and optical parameters through the host device management interface to confirm stable operation.
Usage recommendations
Use certified single-mode LC patch cords and maintain clean connectors to prevent signal loss. Confirm compatibility with the host device's QSFP28 interface and firmware requirements. For long-distance links, perform optical power budget calculations and verify transceiver transmit/receive levels to ensure reliable link margins.
