Finisar FTL4C1QE2C 40Gbps 10KM QSFP+ Optical Transceiver Module

The Finisar FTL4C1QE2C is a 40Gbps QSFP+ optical transceiver designed for 40GBASE-LR4 Ethernet connectivity over single-mode fiber. It supports optical links of up to 10km and provides a compact, hot-pluggable interface for compatible 40Gbps networking equipment.

The module uses an uncooled 4 × 10Gbps CWDM transmitter and a duplex LC optical interface. Its design is intended for long-reach 40GbE applications across single-mode fiber, including data center interconnects, enterprise networks, and network aggregation links. :contentReference[oaicite:0]{index=0}

Finisar FTL4C1QE2C 40GBASE-LR4 Connectivity

The FTL4C1QE2C is designed specifically for 40GBASE-LR4 40 Gigabit Ethernet applications. It supports an aggregate data rate of 41.2Gbps and uses four optical channels to carry the high-speed network signal across a single-mode fiber connection.

The four optical channels use CWDM wavelengths within the 1310nm band. This wavelength-division architecture allows the individual channels to be multiplexed onto the fiber pair while maintaining the required bandwidth for the 40GbE connection. :contentReference[oaicite:1]{index=1}

10KM Single-Mode Fiber Transmission

The transceiver is designed for single-mode fiber (SMF) and supports a maximum link length of 10km. This makes it suitable for longer 40GbE connections where short-range multimode QSFP+ modules are not appropriate.

Four-Channel CWDM Architecture

The FTL4C1QE2C uses four optical channels for 40Gbps transmission. The CWDM architecture combines the optical channels into the fiber link, while the receiver separates the channels at the destination. The module uses DFB laser transmitters and PIN receivers. :contentReference[oaicite:2]{index=2}

QSFP+ and Duplex LC Interface

The QSFP+ form factor provides a compact and hot-pluggable interface for compatible 40Gbps network equipment. The module uses duplex LC receptacles for optical connectivity over a pair of single-mode fibers.

Digital Diagnostic Monitoring

The module provides built-in digital diagnostic functions, including transmit and receive optical power monitoring. These functions are available through the module's I2C management interface in accordance with the QSFP+ MSA. :contentReference[oaicite:3]{index=3}
