The Finisar FTLC1154RDPL is a 100Gbps QSFP28 optical transceiver designed for 100GBASE-LR4 Ethernet applications. It uses LAN-WDM technology over single-mode fiber and supports transmission distances of up to 10 km, making it suitable for high-speed data-center, enterprise, and telecommunications networks.
Description
The Finisar FTLC1154RDPL is a high-performance 100GBASE-LR4 QSFP28 optical transceiver designed to provide high-bandwidth connectivity over single-mode fiber (SMF).
Using LAN-WDM (Local Area Network Wavelength Division Multiplexing) technology, the transceiver combines multiple optical wavelengths to transmit 100Gbps Ethernet over a single duplex fiber connection. This architecture enables high-speed network links over significantly longer distances than short-range multimode solutions.
The module is designed for 10 km reach over suitable single-mode fiber and is typically deployed in data-center interconnects, enterprise backbone networks, campus networks, service-provider infrastructure, and other high-capacity networking environments.
The QSFP28 form factor provides a compact, high-density solution for 100GbE switches, routers, and other compatible network equipment. It is particularly useful in environments where rack space and port density are important considerations.

Optical Technology
The FTLC1154RDPL uses four LAN-WDM optical wavelengths to achieve 100Gbps transmission over single-mode fiber.
The four optical channels are multiplexed onto the fiber for transmission and separated at the receiving end. This allows the transceiver to provide high-speed 100GbE connectivity while using a standard duplex fiber infrastructure.
10km Long-Range Connectivity
The LR4 (Long Range 4) architecture is intended for longer-distance Ethernet links compared with SR4 solutions.
With compatible single-mode fiber infrastructure, the transceiver supports links of up to 10 km, making it suitable for:
- Data-center interconnects
- Campus backbone links
- Metropolitan network connections
- Enterprise core networks
- Service-provider infrastructure
Actual achievable distance depends on the fiber quality, optical budget, connectors, patch panels, and network equipment.
Recommended Applications
- Data Centers
- Data Center Interconnects
- Enterprise Core Networks
- Telecommunications
- Service Provider Networks
- Campus Networks
- High-Speed Backbone Networks
- 100GbE Switch Uplinks
- Router-to-Switch Connections
- High-Bandwidth Infrastructure
Compatibility
The Finisar FTLC1154RDPL is designed for compatible QSFP28 ports supporting 100GBASE-LR4.
Before deployment, verify compatibility with the target switch, router, network adapter, firmware, and vendor transceiver support matrix. Some networking platforms may require vendor-qualified or coded optical modules.
