The module fits QSFP28 ports and enables long-reach single-mode fiber connections where supported by infrastructure.

## Long description

Transceiver CBO QSFP28-100G-LR4 Fiber Optic 100G 1310nm is a QSFP28 form-factor 100 Gigabit optical module designed for long-reach single-mode links. The module operates at a center wavelength around 1310 nm and supports 100G Ethernet over single-mode fiber using LR4 transmission. It is intended for compatible 100G network equipment and fits standard QSFP28 ports to provide high-speed optical connectivity for data centers, aggregation layers and carrier interconnects.
Advantages
This QSFP28 LR4 transceiver offers high-density 100G connectivity in a compact pluggable module, enabling long-reach single-mode links where infrastructure supports LR4. The module is designed for interoperability with standard QSFP28 ports and provides stable optical performance for backbone and aggregation segments. Its compact form factor reduces space requirements in dense rack deployments while supporting high data throughput and simplified cabling for long-distance links.
Suitable for
Data centre core and aggregation links requiring 100G long-reach connectivity
Carrier and metro network interconnects over single-mode fiber
High-bandwidth backbone connections between switches and routers
Key specifications
Form factor: QSFP28 pluggable module
Data rate: 100 Gbps
Optical type: Single-mode fiber (SMF)
Wavelength: around 1310 nm (LR4 specification)
Reach: long-reach links over single-mode fiber (LR4 class)
Connector interface: standard QSFP28 electrical/optical interface
How to use
Install the QSFP28-100G-LR4 module into a compatible QSFP28 port on network equipment while the device is powered down or per the vendor's hot-plug procedure. Connect single-mode fiber terminated with appropriate LC or MPO connectors as required by the transceiver and the system. Verify link status and optical parameters via the host device management interface and allow time for the link to train and stabilize. Follow the equipment manufacturer’s interoperability list to ensure compatibility and expected performance.
Usage recommendations
Ensure clean connector endfaces and use certified single-mode fiber cabling for LR4 links. Verify that the network equipment supports QSFP28 LR4 modules and consult vendor documentation for recommended power budgets, link distances and transceiver settings. Monitor optical power and link diagnostics after installation to confirm stable operation.
