Transceiver CBO H-LR4-QSFP+ 100G LR4 QSFP+ 1310nm fiber optic module

The Transceiver CBO H-LR4-QSFP+ 100G LR4 QSFP+ 1310nm fiber optic module is a single-mode long-reach optical transceiver in a QSFP+ form factor that delivers 100 Gigabit connectivity over optical links. Designed for data center uplinks, carrier networks and high-capacity aggregation, this module uses a 1310 nm wavelength and LR4 multiplexing to support extended distances on single-mode fiber. The compact QSFP+ package enables four-channel optical transport in a single hot-pluggable module, allowing integration into switches, routers and aggregation equipment that accept QSFP+ interfaces.

Advantages

The module offers 100G bandwidth in a standardized QSFP+ footprint, enabling high-density port deployment and simplified hardware compatibility. Its single-mode LR4 optics and 1310 nm operation provide stable performance for long-reach links, reducing the need for intermediate regeneration. As a hot-pluggable transceiver, it supports easier maintenance and rapid replacement without powering down host equipment. The design focuses on interoperability with common networking platforms and on delivering consistent signal quality for carrier-grade and data center environments.

Suitable for

• Data center uplinks and core switches requiring 100G optical links
• Carrier and metro transport networks for long-reach single-mode fiber connections
• Aggregation links between distribution switches and core routers
• High-bandwidth interconnects in campus backbone or service provider networks

Key specifications

• Form factor: QSFP+ (4-channel in one module)
• Nominal bit rate: 100 Gigabit Ethernet
• Optical wavelength: 1310 nm
• Optical type: Single-mode fiber, LR4 multiplexed lanes
• Reach: Designed for long-reach single-mode links (LR4 class)
• Interface: Hot-pluggable QSFP+ electrical/optical connector

How to use

Insert the QSFP+ transceiver into a compatible QSFP+ port on your switch or router while the host device is powered on or off, following the host vendor’s hot-plug guidelines. Ensure that single-mode fiber cables with appropriate LC connectors and LR4 multiplexing support are used, and verify correct polarization and connector cleanliness before connecting. Configure the host interface for 100G operation according to the network equipment’s management interface and monitor link status through the device’s diagnostics.

Usage recommendations

Use clean, tested single-mode fiber and maintain proper patch panel and connector practices to ensure optimal performance. Validate compatibility with the host platform and check link length against LR4 reach specifications. For critical carrier or data center links, enable monitoring and error detection on the host to respond promptly to link degradation.
