Product Highlights
Introducing the 1.25G SFP 850nm 550m LC – a Fiber SFP that redefines short-reach connectivity. While commonly associated with 1G 1310nm for long-haul applications, our 1G Multimode SFP excels in close-quarter deployments with its 850nm wavelength, supporting up to 550m over multimode fiber. As an SFP 1G SX variant, it offers a cost-effective alternative to traditional long-wavelength modules, seamlessly integrating into your existing network infrastructure.
Audio/Video Distribution Systems
The 1.25G SFP 850nm 550m LC module is used in audio/video distribution systems to transmit high-quality audio and video signals over fiber optics. This module ensures that audio and video content can be distributed across large facilities or venues without signal degradation. The 550m range provides flexibility for audio/video distribution in stadiums, conference centers, and theaters, ensuring clear and reliable transmission of content across multiple displays or audio systems.
VoIP and Unified Communication
The 1.25G SFP 850nm 550m LC module plays a significant role in VoIP (Voice over IP) and unified communication systems by enabling high-quality voice and video transmission over local area networks. With a 550m reach, it supports clear, low-latency communication within office buildings, campus environments, and small-to-medium-sized enterprises. This module ensures reliable real-time voice calls, video conferences, and collaboration tools for employees, enhancing productivity and communication efficiency.

This ensures the highest performance, quality, and stability of optical transmission in all of our products.
Product packaging specification
Packing of module products
Put the qualified products into the corresponding model blister box packaging.
The bottom, surface and side of the carton are filled with one piece of anti-static foam to protect the product.According to the requirements of the packing quantity, put the blister box box of the product into the packaging carton. If the space between the blister boxes is large, use a piece of anti-static foam to put it in the middle. The empty space in the end box must be filled with anti-static foam to ensure that it will not be damaged during transportation.
The outer case label is attached to the side position of the outer case,Label the outer case after sealing.
At the time of delivery, the entire outer box should be wrapped with at least 2 layers of wrapping film protection.
