The module uses a 1310nm-band optical architecture and duplex LC connectivity. :contentReference[oaicite:0]{index=0}

The FTL4C1QE2C uses an uncooled four-channel 10Gb/s CWDM transmitter architecture to transport the aggregate 40Gbps signal over a duplex single-mode fiber connection. Its 41.2Gbps aggregate data rate and XLPPI electrical interface make it suitable for high-bandwidth networking applications including data center interconnects, enterprise backbones, metro networks, and switch-to-switch connectivity. :contentReference[oaicite:1]{index=1}

Unlike 40GBASE-SR4 QSFP+ modules, which are designed for short-reach multimode fiber and typically use MPO/MTP connectors, the FTL4C1QE2C is an LR4 module designed for single-mode fiber and uses duplex LC receptacles. This makes it appropriate for longer-distance 40G optical links where an LC-based single-mode fiber infrastructure is available.

The Finisar FTL4C1QE2C supports a maximum link distance of 10km on single-mode fiber. The module is hot-pluggable, operates from a single 3.3V supply, and provides digital diagnostic functions through an I2C management interface. :contentReference[oaicite:2]{index=2}

Finisar FTL4C1QE2C Gen2 QSFP-40GBASE-LR4 Specifications & Features

Overview

The Finisar FTL4C1QE2C is a Gen2 40GBASE-LR4 QSFP+ optical transceiver designed for 40Gbps Ethernet links over single-mode fiber. It combines four 10Gb/s optical channels using CWDM technology and presents the aggregate connection through a compact QSFP+ host interface. The manufacturer specifies a 41.2Gbps aggregate data rate and a maximum 10km link distance on single-mode fiber. :contentReference[oaicite:3]{index=3}

The module is well suited to network environments where 40Gbps connectivity must extend beyond the typical range of multimode SR4 optics. Its duplex LC interface also allows it to connect directly to standard duplex single-mode fiber infrastructure without requiring an MPO/MTP parallel-fiber assembly.

40GBASE-LR4 Optical Technology

40GBASE-LR4 is a long-reach 40Gbps Ethernet optical technology designed for single-mode fiber. The Finisar FTL4C1QE2C uses four 10Gb/s optical channels combined using CWDM technology, allowing the aggregate 40Gbps signal to travel through a duplex single-mode fiber connection. The module is compliant with IEEE 802.3ba 40GBASE-LR4. :contentReference[oaicite:4]{index=4}

This architecture makes the FTL4C1QE2C particularly useful for longer 40G links between data centers, network aggregation points, enterprise facilities, and other locations where short-reach multimode optics are insufficient.

1310nm Optical Technology

The FTL4C1QE2C operates in the 1310nm optical band. Its four optical channels are multiplexed through CWDM technology inside the module, allowing the 40Gbps signal to be transmitted over a duplex single-mode fiber pair. :contentReference[oaicite:5]{index=5}

The optical design is intended for extended-distance single-mode fiber connectivity and provides a maximum specified link distance of 10km on suitable SMF. :contentReference[oaicite:6]{index=6}

Duplex LC Single-Mode Fiber Connectivity

The Finisar FTL4C1QE2C uses duplex LC receptacles and duplex single-mode fiber. One fiber is used for transmission and the other for reception, while the four optical wavelengths are multiplexed internally within the transceiver.

This makes the module a practical choice for installations that already use duplex LC single-mode fiber infrastructure. The complete optical channel should be checked for fiber attenuation, connector loss, splice loss, optical budget and total link distance before deployment.

QSFP+ Form Factor

The compact QSFP+ form factor enables high-density 40Gbps connectivity in compatible switches, routers, network adapters and optical transport platforms. The module is hot-pluggable and follows the QSFP+ MSA interface requirements. :contentReference[oaicite:7]{index=7}

The pluggable architecture simplifies optical module installation, replacement, maintenance and network expansion on supported host platforms.

Digital Diagnostic Monitoring

The FTL4C1QE2C provides digital diagnostic functions through an I2C management interface. The supported monitoring functions include transmitter and receiver optical power monitoring, helping network administrators troubleshoot optical links and monitor module operating conditions. :contentReference[oaicite:8]{index=8}
