## Summary description

CBO QSFP28-100G-LR4 is a fiber optic transceiver module supporting 100G data rate at 1310 nm wavelength. Designed for long-reach single-mode links, it fits QSFP28 ports and enables high-speed uplinks and switch-to-switch connections. Suitable for data centers and carrier networks, it provides reliable optical transmission for backbone and aggregation layers.

## Long description

CBO QSFP28-100G-LR4 Fiber Optic 100G 1310nm is a compact transceiver module designed for long-reach single-mode fiber connections. It provides 100 Gbps aggregate bandwidth in a QSFP28 form factor and operates at the 1310 nm wavelength, enabling high-speed uplinks and switch-to-switch links in data centers and carrier networks. The module supports reliable optical transmission for backbone and aggregation layers and is compatible with systems that accept QSFP28 100G LR4 optics.
Advantages
The transceiver delivers 100G performance in a small QSFP28 package, supporting long-reach links over single-mode fiber at 1310 nm. It is engineered for stable optical transmission with low power consumption and standard electrical and optical interfaces to simplify integration. The module is suitable for dense network environments where compact form factor and high bandwidth are required.
Suitable for
100G uplinks between switches and routers
Long-reach single-mode backbone and aggregation links
Data center interconnects and spine-leaf topologies
Carrier and metro network transport
Key specifications
Form factor: QSFP28
Data rate: 100 Gbps (aggregate)
Optical type: Single-mode fiber
Wavelength: 1310 nm
Reach: long-reach single-mode links (LR4 class)
Connector type: LC (typically used with LR4 optics)
Electrical interface: QSFP28 electrical signaling
How to use
Install the QSFP28 transceiver into a compatible QSFP28 port on a switch, router or other network device following the host equipment vendor’s hot-plug procedures. Connect single-mode fiber cables using appropriate LC connectors and ensure proper polarity and cleanliness of fiber end-faces. After insertion and cable connection, verify link status and configured speed on the network device to confirm the 100G optical link is established.
Usage recommendations
To ensure reliable operation, use single-mode fibers rated for long-reach LR4 links and maintain clean connector end-faces. Verify compatibility with the host device and update device firmware or transceiver compatibility lists if required. Monitor optical power levels and temperature during initial deployment to confirm link margins meet network design requirements.
