FINISAR FTLC9152RGPL 100G QSFP28 SWDM4 Transceiver Module (100G Optical Fiber Module)

About FINISAR FTLC9152RGPL 100G QSFP28 SWDM4 Optical Transceiver in Bangladesh

The FINISAR FTLC9152RGPL is a high-performance 100Gbps QSFP28 SWDM4 optical transceiver designed for high-speed Ethernet connectivity over duplex multimode fiber. It uses four coarse wavelength division multiplexed optical channels to deliver an aggregate 100Gbps data rate through a duplex LC fiber connection.

Unlike conventional 100GBASE-SR4 modules that use an MPO connector and four separate fiber pairs, the FTLC9152RGPL uses SWDM4 technology with four wavelengths—approximately 850nm, 880nm, 910nm and 940nm—over duplex multimode fiber. This allows 100GbE connectivity using a duplex LC fiber infrastructure. :contentReference[oaicite:1]{index=1}

Finisar specifies maximum link lengths of 75 meters on OM3, 100 meters on OM4 and 150 meters on OM5 duplex multimode fiber. The module supports a 103.1Gb/s aggregate bit rate, I²C management and less than 3.5W power dissipation. :contentReference[oaicite:2]{index=2}

FINISAR FTLC9152RGPL 100G SWDM4 Specifications & Features

Overview

The FINISAR FTLC9152RGPL provides 100GbE connectivity using SWDM4 optical technology. Four optical wavelengths are multiplexed over duplex multimode fiber, allowing a 100Gbps connection to use a conventional duplex LC interface rather than the MPO interface typically associated with parallel 100G SR4 optics.

This makes the module particularly useful for data centers and enterprise networks where duplex multimode fiber infrastructure is already installed.

100G SWDM4 Technology

SWDM4 stands for Shortwave Wavelength Division Multiplexing using four optical wavelengths. The FTLC9152RGPL uses four wavelengths in the shortwave optical region to carry four 25Gb/s channels over duplex multimode fiber.

The four wavelengths are approximately 850nm, 880nm, 910nm and 940nm. By multiplexing these channels, the module achieves an aggregate 100Gbps Ethernet connection over only two multimode fiber strands. :contentReference[oaicite:3]{index=3}

Duplex LC Connectivity

One of the major advantages of the FTLC9152RGPL is its duplex LC optical interface.

Traditional 100GBASE-SR4 modules commonly use MPO/MTP connectors with parallel fibers. The FTLC9152RGPL instead uses SWDM4 wavelength multiplexing, allowing 100GbE to operate over a duplex multimode LC fiber connection.

850nm, 880nm, 910nm and 940nm Wavelengths

The FTLC9152RGPL uses four SWDM optical wavelengths centered around 850nm, 880nm, 910nm and 940nm. Each wavelength carries one 25Gb/s optical channel.

This wavelength-division architecture allows four channels to share the same pair of multimode fibers while maintaining the 100Gbps aggregate Ethernet data rate. :contentReference[oaicite:4]{index=4}

OM3, OM4 and OM5 Fiber Reach

Finisar specifies different maximum link lengths depending on the multimode fiber category:

These distances are based on the specified optical characteristics of the respective fiber grades. Actual performance depends on fiber quality, connector losses, patching, installation conditions and the complete optical budget. :contentReference[oaicite:5]{index=5}

Four 25Gb/s Optical Channels

The FTLC9152RGPL uses four optical channels, each carrying approximately 25Gbps. These channels are wavelength-multiplexed onto the duplex multimode fiber pair.

The host-side electrical interface is a 4 × 25G CAUI-4 interface, allowing the module to connect to compatible 100GbE QSFP28 ports. :contentReference[oaicite:6]{index=6}

Digital Diagnostics

The module provides an I²C management interface for digital diagnostics and transceiver identification. Compatible host equipment can access supported optical and operational parameters through the management interface.

The exact monitoring values displayed depend on the switch, router or network operating system supporting the transceiver.

Power Efficiency

Finisar specifies power dissipation of less than 3.5W for the FTLC9152RGPL. The module operates from a single 3.3V power supply. :contentReference[oaicite:7]{index=7}

This makes it appropriate for high-density 100GbE switch deployments where multiple QSFP28 modules may operate simultaneously.

Data Center Connectivity

The FTLC9152RGPL is particularly useful for data centers that have duplex multimode LC fiber infrastructure but need to upgrade individual network links to 100Gbps.

Because SWDM4 uses wavelength multiplexing rather than four separate fiber pairs, existing duplex MMF cabling can be used for suitable 100G connections within the specified distance limits.

FTLC9152RGPL vs 100GBASE-SR4

The major practical difference is the cabling architecture: SWDM4 enables 100GbE over a duplex LC multimode fiber pair, while conventional SR4 uses parallel optical lanes over an MPO/MTP connection.

SWDM4 and Existing Duplex MMF Infrastructure

The FTLC9152RGPL can be particularly valuable when a data center already has duplex LC multimode fiber installed. Instead of replacing the entire fiber path with MPO-based parallel-fiber cabling, compatible SWDM4 modules can use the existing duplex fiber architecture within the supported distance and optical specifications.

Compatibility

The FTLC9152RGPL is a QSFP28 MSA-compliant optical module, but host compatibility should still be verified before purchase. Finisar's specification identifies compliance with the QSFP28 MSA and IEEE 802.3bm CAUI-4. :contentReference[oaicite:8]{index=8}

Check the exact switch, router or network platform for supported 100G SWDM4 optics, transceiver coding, firmware and optical standards.

Do not assume that every QSFP28 port supporting 100GBASE-SR4 will automatically support SWDM4.

Optical Link Planning

For reliable operation, the complete optical path should be checked before deployment.
