A QSFP-100G-LR4 Optical Transceiver Module


The QSFP-100G-LR4 optical transceiver is a hot-swappable device used for high-speed data transmission in telecommunication networks. It allows for 100 Gigabit Ethernet (100GBase-LR4) connections over single-mode fibre (SMF) for a distance of up to 10 kilometres.

Here’s a breakdown of its key features:

Speed and Reach: Supports 100 Gigabit Ethernet speeds at a maximum distance of 10km.

Form Factor: Utilises the QSFP28 (Quad Small Form-factor Pluggable) form factor for easy installation and removal in compatible network equipment.

Wavelength: Operates at a wavelength of 1310nm, suitable for single-mode fibre optic cables.

Connection: Employs duplex LC connectors for secure and reliable connections.

Standards Compliance: Adheres to IEEE 802.3ba 100GBASE-LR4 and SFF-8665/SFF-8636 standards for interoperability.

Digital Diagnostics: Provides real-time monitoring of operational parameters through the I2C interface for proactive maintenance (may vary depending on the manufacturer).

In summary, the QSFP-100G-LR4 transceiver is a high-performance adapter that enables data transmission at extremely fast speeds over long distances on single-mode fibre optic cables. It’s commonly used in data centres and service provider networks for high-bandwidth applications.
