Transceiver CBO OC40-LR4-OPT-1 QSFP 100G fiber optic long‑reach module

The Transceiver CBO OC40-LR4-OPT-1 QSFP 100G fiber optic long‑reach module is a hot-pluggable QSFP transceiver engineered for 100 Gigabit Ethernet links over single‑mode fiber. It is designed to fit QSFP ports in switches, routers and optics‑enabled servers, providing a compact solution for backbone and metro connections that require extended reach. The module supports long‑reach transmission using LR4 optics, enabling high‑capacity data transport while reducing the need for multiple parallel fibers and simplifying cabling topology.

Advantages

This QSFP 100G transceiver offers high port density in a small form factor and supports long‑reach single‑mode fiber links suitable for backbone and metro networks. Its hot‑pluggable design allows replacement or upgrades without powering down equipment. The LR4 optics provide wavelength division multiplexing across four channels to achieve a 100G aggregate data rate, helping to consolidate traffic and reduce fiber count. The module is compatible with standard QSFP cages and common networking platforms that accept QSFP‑based 100G optics.

Suitable for

• High-capacity backbone links between data centers and aggregation switches
• Metro Ethernet connections requiring long-reach single‑mode fiber
• Upgrading switches and routers to 100 Gigabit Ethernet without changing chassis
• Optics-enabled servers that need direct 100G fiber connectivity

Key specifications

• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Data rate: 100 Gigabit Ethernet
• Fiber type: single‑mode fiber
• Optical interface: LR4 (four-wavelength long‑reach MPO/LC optics, multiplexed)
• Hot‑pluggable: yes
• Typical applications: backbone, metro, data center interconnects

How to use

Insert the QSFP transceiver into a compatible QSFP port on a switch, router or server module while the host device is powered on, ensuring proper alignment and secure seating. Connect single‑mode fiber using the corresponding multiplexed LR4 connector type supported by the module and verify link status through the host device management interface. When removing the transceiver, follow standard hot‑swap procedures and use the built‑in latch or release mechanism to avoid damage to the module or the port.

Usage recommendations

Use certified single‑mode duplex or MPO cabling that matches the LR4 optical interface and maintain proper fiber cleanliness. Confirm compatibility with the host device vendor’s optics guide and firmware for 100G QSFP LR4 modules. For long‑reach links, calculate link budget including fiber attenuation and connector losses, and test end‑to‑end connectivity and error rates after installation.
