## Long description

The CBO QSFP28-LR4-XCVR Transceiver 100G 1310 nm 10 km is an optical QSFP28 module designed for 100 Gigabit Ethernet links over single-mode fiber. It operates at 1310 nm wavelength and supports a link distance of up to 10 km, providing hot-pluggable QSFP28 connectivity for data center switches, routers and server uplinks. The module is intended for high-density environments and for interconnects that require long-reach single-mode fiber transmission while maintaining standard QSFP28 form-factor compatibility.
Advantages
This transceiver delivers a 100G data rate in a compact QSFP28 package and is hot-pluggable for flexible deployment and maintenance without powering down equipment. The single-mode 1310 nm optics enable reliable transmission over distances up to 10 km, supporting aggregation and long-reach links between racks or sites. Its compatibility with standard QSFP28 ports simplifies integration into existing 100 Gigabit Ethernet infrastructures.
Suitable for
100 Gigabit Ethernet connections in data centers
