About Finisar FTL4C1QE1C GEN1 QSFP-40GBASE-LR4 10km 1310nm LC SMF Transceiver in Bangladesh

The Finisar FTL4C1QE1C GEN1 is a high-performance 40Gbps QSFP+ optical transceiver designed for 40GBASE-LR4 Ethernet connectivity over single-mode fiber. As a first-generation Finisar 40GBASE-LR4 product, the module provides long-reach 40Gbps optical connectivity with a maximum link distance of up to 10km on suitable single-mode fiber.

The FTL4C1QE1C uses four optical channels with a CWDM architecture to transport the aggregate 40Gbps signal through a duplex LC optical interface. The module operates in the 1310nm optical band and is designed for data center interconnects, enterprise backbone networks, telecom infrastructure, and long-distance 40G switch-to-switch connectivity.

Finisar identifies the FTL4C1QE1C as a first-generation product, with the product code indicating a 40GBASE-LR4 compliant optical interface, first-generation design and commercial temperature rating. The published specification lists a 41.2Gbps aggregate bit rate, duplex LC connectors, 10km SMF reach, digital diagnostics and less than 3.5W power dissipation.

Unlike 40GBASE-SR4 QSFP+ modules designed for short-reach multimode fiber and MPO/MTP connectors, the FTL4C1QE1C is an LR4 transceiver intended for single-mode fiber and uses duplex LC connectivity. This makes it suitable for existing LC-based SMF infrastructure and longer-distance 40G Ethernet deployments.

Finisar FTL4C1QE1C GEN1 QSFP-40GBASE-LR4 Specifications & Features

Overview

The Finisar FTL4C1QE1C is a GEN1 40GBASE-LR4 QSFP+ optical transceiver designed for high-bandwidth 40Gbps Ethernet links over single-mode fiber. The manufacturer documentation identifies the module as a first-generation product and specifies support for 41.2Gbps aggregate bit rates and a maximum 10km link length on SMF.

The module converts four electrical data channels into four CWDM optical signals, multiplexes them into a single optical connection, and transmits the combined signal over duplex single-mode fiber. At the receiving end, the optical signal is demultiplexed back into the four electrical channels.

This architecture allows a 40Gbps connection to use a conventional duplex LC single-mode fiber pair rather than the parallel MPO/MTP cabling normally associated with 40GBASE-SR4.

40GBASE-LR4 Optical Technology

40GBASE-LR4 is a long-reach 40Gbps Ethernet optical technology designed for single-mode fiber. The FTL4C1QE1C uses four CWDM optical channels to transport the aggregate 40Gbps signal through a duplex single-mode fiber connection.

The four optical channels are multiplexed inside the transceiver, allowing the module to use a standard duplex LC optical interface. This makes LR4 particularly useful when an organization needs to extend 40G Ethernet over existing single-mode fiber infrastructure.

The FTL4C1QE1C supports a maximum link distance of 10km on single-mode fiber, subject to the complete optical link budget and installation conditions.

1310nm CWDM Optical Architecture

The Finisar FTL4C1QE1C operates in the 1310nm optical band and uses four CWDM optical channels. The optical architecture converts four electrical input channels into four wavelength channels, multiplexes them for transmission, and performs the reverse operation at the receiver.

This internal multiplexing allows four 10Gbps channels to be carried over only two single-mode optical fibers. The architecture is therefore different from 40GBASE-SR4, which uses multiple parallel multimode fiber lanes.

Duplex LC Single-Mode Fiber Connectivity

The FTL4C1QE1C uses duplex LC optical receptacles and is designed for single-mode fiber. One fiber carries the transmitted optical signal and the second fiber carries the received signal.

Before deployment, verify the single-mode fiber type, connector condition, insertion loss, splice loss, optical power budget and total link distance. Proper optical cleaning and connector inspection are also recommended for reliable 40G operation.

GEN1 Finisar QSFP+ Design

The FTL4C1QE1C is specifically identified by Finisar as a first-generation 40GBASE-LR4 product. The product code includes the "1" generation identifier, distinguishing it from later FTL4C1QE2C Gen2 and other subsequent versions.

When replacing or matching an existing transceiver, the exact part number and generation should be checked because host-device compatibility, firmware support and optical specifications can vary between different transceiver revisions.

QSFP+ Form Factor

The compact QSFP+ form factor provides high-density 40Gbps connectivity for compatible networking equipment. The FTL4C1QE1C is designed for supported switches, routers, network adapters and other platforms equipped with compatible QSFP+ interfaces.

The hot-pluggable design allows optical modules to be installed or replaced on supported equipment without replacing the complete networking platform. Actual hot-plug functionality depends on the host system.

Digital Diagnostic Monitoring

The FTL4C1QE1C provides digital diagnostic functions through an I2C management interface. The module supports diagnostic monitoring including transmitter and receiver optical power information on compatible host platforms.

Digital diagnostics can help network administrators monitor optical link conditions and troubleshoot issues related to fiber connectivity, optical power and module operation.

Compatibility

• Compatible Finisar 40G QSFP+ platforms
• Compatible 40G QSFP+ switches
• Compatible 40G routers
• Compatible enterprise networking platforms
• Compatible data center networking equipment
• Compatible optical transport platforms with supported QSFP+ interfaces
• Duplex single-mode fiber infrastructure

Actual compatibility depends on the host equipment model, firmware, transceiver coding, supported optics list and platform requirements. Always verify the exact host device and supported optical module list before purchase.

Finisar FTL4C1QE1C GEN1 vs FTL4C1QE2C GEN2

Although the two modules share the same basic 40GBASE-LR4 application, they are different Finisar generations. For replacement applications, the exact host-device compatibility and supported optics list should be confirmed rather than assuming that every Gen1 and Gen2 module is interchangeable.
