## Summary description

CBO QSFP28-100G-LR4 is a QSFP28 fiber optic transceiver module supporting 100G LR4 connectivity. Designed for long-reach single-mode fiber links, it implements 4-channel LR4 transmission in a compact QSFP28 form factor. Suitable for data center interconnects, metro networks and high-speed backbone links, it enables high-bandwidth, low-latency 100 Gigabit Ethernet connections.

## Long description

The Transceiver CBO QSFP28-100G-LR4 Fiber Optic 100G LR4 Module is a compact QSFP28 form-factor optical transceiver designed for long-reach single-mode fiber links. It provides 100 Gigabit Ethernet connectivity over LR4 transmission, using four wavelength channels to carry high-bandwidth data across extended distances. The module is intended for use in data center interconnects, metro networks and backbone links where low latency and reliable 100G transport are required.
Advantages
This QSFP28 LR4 module delivers multi-channel 100G performance in a small form factor, enabling high port density in switches and routers. It supports long-reach single-mode fibers, which reduces the need for intermediate repeaters or regeneration in metro and inter-site links. The transceiver is designed for interoperability with standard QSFP28 cages and electrical interfaces, and it provides consistent, low-latency transmission for demanding network environments.
Suitable for
Data center interconnects and leaf-spine fabrics
Metro and regional optical links requiring long-reach single-mode connectivity
High-speed backbone links and aggregation layers
Upgrading network equipment to 100 Gigabit Ethernet
Key specifications
Form factor: QSFP28
Data rate: 100 Gigabit Ethernet (4×25G lanes)
Transmission type: LR4 over single-mode fiber
Wavelength: 4-channel LR4 wavelength division
Connector type: duplex LC (compatible with LR4 optics)
Typical reach: long-reach links (single-mode fiber)
Electrical interface: QSFP28 compatible
How to use
Install the module into a compatible QSFP28 port on a switch, router or transponder in accordance with the host equipment manufacturer’s instructions. Ensure fiber cabling uses single-mode fiber with appropriate LC connectors and observe correct polarity when connecting transmit and receive pairs. Verify that the host device recognizes the module and configures the port for 100G LR4 operation. Monitor link status and optical power levels through the host management interface to confirm proper operation.
Usage recommendations
Handle the optical transceiver following standard electrostatic discharge (ESD) precautions and keep dust caps on connectors when not in use. Use certified single-mode fiber and maintain connector cleanliness to ensure optical performance. Confirm compatibility with the network equipment vendor’s supported transceivers list if required by your operational policies.
