## Summary description

Optical QSFP+ transceiver module ALCATEL QSFP-100G-LR4 for 100 Gigabit Ethernet links using LR4 specification. Designed to provide 100G single-lambda connectivity over single-mode fiber for long-reach applications, it fits QSFP+ ports and supports high-density data center and carrier transport installations.

## Long description

The ALCATEL QSFP-100G-LR4 QSFP+ 100G LR4 optical transceiver module is designed for 100 Gigabit Ethernet links over single-mode fiber using the LR4 specification. It provides single-lambda 100G connectivity suitable for long-reach applications and fits QSFP+ ports used in high-density data center and carrier transport environments. The module supports standard electrical and optical interfaces for interoperability with compatible networking equipment.
Advantages
This QSFP+ LR4 transceiver delivers high-bandwidth single-mode fiber connectivity with long-reach performance while occupying a compact QSFP+ form factor. It supports low-latency data transfer and enables high port density on switches and routers. The module is field-replaceable, hot-pluggable, and designed to work with standard LR4 optical specifications, providing predictable optical performance for link planning and network upgrades.
Suitable for
 100 Gigabit Ethernet links between data center aggregation and core switches
 Long-reach interconnects over single-mode fiber in campus and metro networks
 Carrier transport and network operator backhaul applications
 High-density blade and modular systems requiring QSFP+ 100G ports
Key specifications
 Form factor: QSFP+ (quad small form-factor pluggable)
 Data rate: 100 Gbit/s
 Optical specification: LR4 for single-mode fiber long-reach operation
 Wavelength: multiple lanes combined to LR4 wavelength allocation for 100G single-lambda equivalent
 Connector type: standard LC or MPO interface as defined by LR4 implementation (verify with system)
 Hot-pluggable: supports plug-and-play replacement in compatible QSFP+ ports
 Operating environment: designed for data center and carrier-grade deployment
How to use
Install the module into a compatible QSFP+ port on a switch, router or optical transport device following the host equipment manufacturer’s instructions. Ensure that fiber type and connector orientation match the LR4 single-mode requirements and that link margin, optical power and receiver sensitivity are within the expected ranges for your installation. After insertion, verify link status and speed through the device management interface and perform any required diagnostics or firmware checks to confirm interoperability.
Usage recommendations
 Confirm compatibility with the host hardware and the required optical connector type before installation. Use certified single-mode fiber and follow proper fiber handling practices to avoid contamination. For long-reach links, plan for optical power budget and dispersion limits and perform end-to-end testing after deployment to validate link performance.
