Transceptor ótico QSFP28 CBO Q28-100G-LR4 100G LR4

CBO Q28-100G-LR4 is a QSFP28 optical transceiver module that supports 100G LR4 operation over single-mode fiber. It provides a compact pluggable interface for 100 Gigabit Ethernet, designed to enable long-reach links between switches, routers and transport equipment. The module is intended for data center uplinks and carrier network applications where high-bandwidth, long-distance transmission and hot‑swap capability are required.

Advantages

The transceiver offers high-density 100G connectivity in a QSFP28 form factor, allowing efficient use of port space in racks and chassis. It supports long-reach single-mode links, enabling reliable transmission over extended distances. Hot‑pluggable design allows service replacement without powering down the host equipment. The module conforms to LR4 transmission characteristics, delivering four-wavelength multiplexed channels for aggregated 100G throughput.

Suitable for

• Data center spine and leaf uplinks requiring 100G long-reach connectivity
• Carrier and metro transport links over single-mode fiber
• Aggregation links between switches and routers in campus and service provider networks
• Network equipment requiring hot‑swappable 100G QSFP28 modules

Key specifications

• Interface: QSFP28 pluggable form factor
• Data rate: 100 Gigabit Ethernet (LR4 mode)
• Fiber type: single‑mode fiber (SMF)
• Transmission: four‑wavelength multiplexed LR4
• Reach: long‑reach single‑mode links (LR4 class)
• Hot‑swap: hot‑pluggable module design

How to use

Install the QSFP28 module into a compatible QSFP28 port on your switch, router or transport device following the host equipment manufacturer’s insertion procedure. Use appropriate single‑mode fiber cabling and compatible LC duplex or MPO/MTP patching as required by host interface breakout configuration. Monitor link status via the host device to verify signal loss and link integrity. For hot‑swapping, remove and insert the module while observing the equipment’s guidance to avoid receiving/transmitting during unsafe conditions.

Recommendations

Ensure compatibility with the host device and supported LR4 link distances before deployment. Use clean, certified single‑mode fiber connectors and follow ESD precautions during handling. Verify optical budgets and connector types in your network design to achieve required reach and performance.
