NETLINK SFP Module 1.25G 20KM 1310+1490 LC Single Mode (Pair)
Reliable Bi-Directional Fiber Transceiver Pair for High-Speed Communication over 20KM
The NETLINK SFP Module 1.25G 20KM 1310+1490 LC Single Mode (Pair) is a high-performance optical transceiver set designed for efficient, bi-directional data transmission over single-mode fiber (SMF). This module pair uses advanced Wavelength Division Multiplexing (WDM) technology to enable two-way communication over a single fiber strand, making it an ideal choice for Fiber-to-the-Home (FTTH), metro access networks, enterprise backbones, and telecom networks that require reliable, long-distance communication.
Offering a 1.25Gbps data transfer rate and up to 20 kilometers of transmission range, this transceiver pair is perfect for environments where cost-effective, stable, and compact network solutions are essential.
Efficient Single-Fiber Bi-Directional Transmission
This SFP module pair uses WDM technology to facilitate full-duplex communication through a single fiber strand. One transceiver operates at 1310nm for transmission and 1490nm for reception, while the other does the opposite. This innovative approach not only reduces the fiber infrastructure needed by half but also significantly lowers installation and maintenance costs.
Bi-directional SFP modules are particularly beneficial in scenarios where fiber availability is limited or cable management must be optimized.
1.25Gbps Data Rate for Seamless Connectivity
With a data transmission speed of 1.25Gbps, the NETLINK SFP modules support Gigabit Ethernet and are compatible with switches, routers, media converters, and OLT/ONT equipment. This makes them highly suitable for bandwidth-intensive tasks such as video streaming, VoIP, data backups, and inter-building communication.
You get fast, efficient, and lag-free data transmission over long distances—critical for today’s high-speed digital environments.
LC Connector – Compact and Secure
Equipped with an LC (Lucent Connector) interface, these modules ensure a compact, secure, and low-loss connection. The LC interface is widely used in modern network equipment for its high-density design and excellent optical performance, making it a top choice for data centers and enterprise networks.
The LC connector helps in saving panel space while providing reliable signal transmission with minimal insertion loss.
Hot-Pluggable and MSA-Compliant
These SFP modules are hot-pluggable, allowing for convenient installation, removal, and replacement without shutting down the entire system. This feature ensures business continuity and reduces downtime during maintenance or network upgrades.
They also follow the Multi-Source Agreement (MSA) standards, meaning they can be used with a wide range of equipment from various vendors without compatibility issues.
Digital Diagnostic Monitoring (DDM) Supported
The NETLINK SFP pair supports Digital Diagnostic Monitoring (DDM), enabling network administrators to monitor real-time parameters such as:
Optical output/input power
Transceiver temperature
Supply voltage
Laser bias current
This enhances proactive troubleshooting and ensures long-term performance by detecting potential issues before they affect the network.
Robust and Energy-Efficient Design
Designed to withstand harsh environments, these modules operate in a wide temperature range from -10°C to +70°C and feature durable metal housing for superior EMI shielding and thermal dissipation. They consume minimal power, making them ideal for energy-conscious installations.
