## Summary description

CBO QSFP28-LR4-XCVR-I is a QSFP28 optical transceiver supporting 100G data rate with wavelength 1310 nm and a reach of up to 10 km over single‑mode fiber. Designed for high‑speed links in data centers and carrier networks, it provides four‑lane LR4 transmission, hot‑pluggable form factor and interoperability with QSFP28 ports for uplinks and long‑reach connections.

## Long description

The Optical Transceiver CBO QSFP28-LR4-XCVR-I 100G 1310nm 10km is a hot-pluggable QSFP28 module designed for 100 Gigabit Ethernet links over single‑mode fiber. It implements four‑lane LR4 transmission at a central wavelength around 1310 nm and supports a link length of up to 10 km, making it suitable for uplinks, aggregation and long‑reach connections in data centers and carrier networks. The form factor is compatible with standard QSFP28 ports and supports typical power and control interfaces for optical modules.
Advantages
This QSFP28 transceiver offers 100G bandwidth in a compact, hot‑swappable package, enabling rapid upgrades and maintenance without system downtime. Four‑lane LR4 design provides wavelength‑division multiplexing for efficient use of single‑mode fiber and predictable optical performance across links up to 10 km. Compatibility with common QSFP28 interfaces ensures interoperability with many switches and routers that accept QSFP28 modules.
Suitable for
100G uplink and aggregation links between switches in data centers
Carrier and metro network long‑reach connections up to 10 km
High‑speed server interconnects where QSFP28 ports are available
Situations requiring hot‑pluggable replacements or rapid provisioning
Key specifications
Data rate: 100 Gbps (QSFP28, four lanes)
Wavelength: 1310 nm (LR4 multi‑wavelength architecture)
Maximum reach: up to 10 km over single‑mode fiber
Form factor: QSFP28, hot‑pluggable
Fiber type: single‑mode fiber (SMF)
Interface: electrical QSFP28 host connector
Typical application: 100G Ethernet and compatible protocols
How to use
Install the QSFP28 transceiver into a compatible QSFP28 port on a switch, router or host adapter while the system is powered on, using the release latch to secure the module. Connect single‑mode fiber with appropriate LC duplex or MPO connections as required by the host hardware and ensure correct polarity. Verify link status and diagnostics through the host device management interface and allow a short time for the optical link to train and reach full bandwidth. When replacing modules, power‑down is typically not required, but follow the equipment vendor’s hot‑swap guidance.
Usage recommendations
Use certified single‑mode fiber with proper connectors and maintain clean fiber endfaces to ensure optical performance. Confirm host compatibility with QSFP28 LR4 modules and verify supported protocols and transceiver enablement in the device firmware or configuration. For reliable long‑reach links, monitor optical power and BER via host diagnostics and follow standard safety procedures for handling optical transceivers.
