Fiber Optic Transceiver CBO QSFP28-100G-LR4 — 100G LR4

The BlueOptics Fiber Optic Transceiver CBO QSFP28-100G-LR4 is a compact QSFP28 module engineered for 100G LR4 single‑mode fiber links. It delivers a pluggable interface for high‑speed applications such as 100 Gigabit Ethernet and carrier transport, enabling long‑reach connections between switches, routers and optical equipment. The module supports hot‑swappable installation and is designed for data center and service provider environments where reliable 100G connectivity over single‑mode fiber is required.

Advantages

This QSFP28 LR4 transceiver provides high aggregate bandwidth in a small form factor, reducing port density constraints while supporting long‑reach single‑mode links. Its QSFP28 interface allows interoperability with standard 100G ports and simplifies upgrades from lower speeds. Built for stable optical performance, the module supports pluggable replacement without system downtime due to hot‑swap capability.

Suitable for

• 100 Gigabit Ethernet links in data centers
• Long‑reach single‑mode fiber connections between buildings or equipment rooms
• Carrier and metro optical transport networks
• High‑capacity uplinks between aggregation and core switches

Key specifications

• Form factor: QSFP28 compact pluggable transceiver
• Data rate: 100 Gbit/s aggregate
• Fibre type: single‑mode fiber (SMF)
• Transmission type: LR4 (long reach, four‑wavelength)
• Interface: duplex LC (or appropriate MPO to LC breakout depending on system)
• Operation: hot‑swappable modular design
• Typical use range: long‑reach single‑mode links (carrier and data center distances)

How to use

Install the QSFP28 module into a compatible QSFP28 or backward‑compatible port following the host device manufacturer’s insertion procedure. Connect single‑mode fiber using the appropriate cabling and connectors, observing correct fibre polarity. After insertion, verify link status and optical parameters through the host system management interface. For removal, ensure the port is disabled if required by the host and extract the module using the release mechanism.

Recommendations

Handle the optical interfaces carefully: keep dust caps on unused ports, clean connectors before mating, and avoid bending fibers beyond recommended radii. Validate compatibility with the host equipment and verify optical budget and link distance before deployment to ensure stable 100G LR4 operation.
