Optický transceiver CBO QSFP28-100G-LR4 BO28L13610D 100G LR4

CBO QSFP28-100G-LR4 BO28L13610D 100G LR4 is a fiber optic QSFP28 transceiver module engineered for 100 Gbps links over single-mode fiber using LR4 optics. The module fits standard QSFP28 ports and provides long-reach transmission suitable for inter-rack, data center aggregation and core links. Designed for interoperability and straightforward installation, it extends network capacity while maintaining compatibility with QSFP28-compliant switches and routers.

Advantages

The transceiver delivers 100G line rate over four wavelength lanes with LR4 optics, enabling long-distance single-mode connections without additional multiplexing hardware. Its QSFP28 form factor supports hot-plug installation in compatible ports and reduces space compared with multiple smaller modules. The design focuses on stable optical performance, straightforward interoperability and predictable power consumption, which helps simplify network upgrades and equipment replacement.

Suitable for

• Data center uplinks and spine-to-leaf aggregation links
• Long-reach single-mode connections between buildings or campus sites
• Core network links and high-capacity transport circuits
• Network equipment requiring QSFP28-compatible 100G LR4 optics

Key specifications

• Form factor: QSFP28
• Data rate: 100 Gigabit per second (100G)
• Optical type: LR4 (long reach, 4 wavelengths)
• Fiber type: Single-mode fiber (SMF)
• Connector interface: Duplex LC (via MPO to LC conversion as required by LR4 modules)
• Operating mode: 4×25G wavelength lanes
• Typical application: Long-reach links in data center and metro/core networks

How to use

Install the QSFP28 module into a compatible QSFP28 port on a switch, router or transponder while the equipment is powered according to the host vendor guidelines for hot-plug modules. Connect single-mode fiber using appropriate patch cords and, if necessary, MPO-to-LC breakout cables or fanouts designed for LR4 modules. Verify link status and optical parameters via the host device management interface and confirm module compatibility with the switch or router firmware to ensure proper negotiation of 100G operation.

Recommendations

Use certified single-mode fiber and clean connector endfaces before mating. Confirm optical budget and link distance against network design requirements, and consult the host equipment compatibility list for supported QSFP28 LR4 modules. Monitor temperature and receive/transmit parameters after installation to ensure stable operation.
