1471 Optical Module

The 1471 optical module refers to a family of fiber optic transceivers and CWDM modules, including 10GBASE-LR SFP+ and CWDM SFP modules operating at 1471nm wavelength.

Overview

The 1471 module can refer to several types of optical devices depending on the application:

1. 10GBASE-LR SFP+ Transceiver (FTLX1471D3BCL)
   • Designed for 10 Gigabit Ethernet over single-mode fiber.
   • Operates at 1310nm for long-range transmission.
   • Uses LC duplex connectors and is compatible with Finisar (Cisco Code) hardware.
   • Suitable for switches, routers, storage systems, and other network devices.
   • Provides both transmit and receive functions in a single module, ensuring full-duplex communication .
2. CWDM SFP Modules (1471nm)
   • Supports 1.25Gbps transmission over distances up to 120 km.
   • Designed for ultra-long-distance point-to-point networks.
   • Uses duplex LC connectors and operates in the CWDM wavelength band (1471–1611nm).
   • Ideal for campus interconnections, enterprise networks, and CWDM multiplexing applications .
   • Can be integrated with passive CWDM devices to save fiber resources and reduce costs.
3. OADM Fiber Optic Modules (1471nm)
   • Optical Add-Drop Modules allow adding or dropping a specific wavelength in a fiber network.
   • Typically mounted in 1U or 3U panels, supporting modular expansion.
   • Uses LC or SC connectors with PC or APC polishing.
   • Can be used in both directions, with multiple patch cords enabling full add/drop functionality.
   • Suitable for CWDM or WDM networks to multiplex multiple wavelengths over a single fiber .

Key Features

• Connector Types: LC or SC duplex, PC or APC polished.
• Transmission Distance: Ranges from short-range (10GBASE-LR up to 10 km) to ultra-long-range CWDM SFP (up to 120 km).
• Applications: Ethernet, storage networks, campus interconnects, CWDM/WDM multiplexing, and 5G network backhaul.
• Temperature Range: Industrial-grade modules support -40°C to +85°C for outdoor deployment .
• Compatibility: Works with standard MSA-compliant hardware and can replace official Finisar modules for cost-effective solutions .

Summary

The 1471 optical module is a versatile designation covering SFP+ transceivers, CWDM SFP modules, and OADM modules. Selection depends on the required data rate, transmission distance, wavelength, and network architecture. For long-distance CWDM applications, the 1471nm SFP module is ideal, while for 10G Ethernet, the FTLX1471D3BCL SFP+ transceiver is suitable. OADM modules provide flexible wavelength add/drop functionality in fiber networks.
