NETLINK SFP Module 1.25G 40KM 1310+1490 LC Single Mode (Pair)
Reliable Long-Distance Gigabit Optical Transceiver with LC Interface and Bi-Directional WDM Technology
The NETLINK SFP Module 1.25G 40KM 1310+1490 LC Single Mode (Pair) is a high-performance bi-directional optical transceiver designed for long-distance data transmission over a single-mode fiber (SMF). Utilizing Wavelength Division Multiplexing (WDM) technology, this SFP pair enables simultaneous transmission and reception of data through a single strand of fiber, significantly reducing fiber usage and infrastructure costs.
Engineered for high reliability and wide compatibility, this module supports a 1.25Gbps data rate and a transmission range of up to 40 kilometers, making it ideal for metro Ethernet networks, fiber-to-the-home (FTTH) deployments, enterprise backbone systems, and service provider applications.
Bi-Directional WDM Over Single Fiber
The key feature of this SFP module pair is its use of bi-directional WDM technology. One module transmits at 1310nm and receives at 1490nm, while its pair does the opposite. This approach allows full-duplex communication over a single optical fiber, doubling fiber efficiency and making it an excellent choice for areas with limited fiber availability.
This bi-directional design is ideal for cost-sensitive network expansions and deployments that require optimal use of existing fiber infrastructure.
1.25Gbps Gigabit Performance
These NETLINK SFP modules deliver a consistent 1.25Gbps transmission rate, supporting Gigabit Ethernet, switches, routers, and other Layer 2/3 network devices. Whether for streaming, data transfer, or service delivery, the high-speed capability ensures seamless communication with minimal latency.
LC Interface – Compact and Precise
The modules feature an LC (Lucent Connector) interface, known for its compact size and secure latching mechanism. LC connectors are ideal for high-density fiber optic networks, offering low insertion loss and high performance. Their precision alignment makes them particularly suitable for high-speed and long-distance communication links.
Hot-Pluggable and MSA-Compliant
NETLINK’s SFP modules are hot-swappable, meaning they can be inserted or removed without powering down network devices. This reduces network downtime and supports fast upgrades or maintenance. They are also Multi-Source Agreement (MSA) compliant, ensuring interoperability with a wide range of network equipment from various manufacturers.
This standardization makes them ideal for plug-and-play deployment across new and legacy systems alike.
Digital Diagnostic Monitoring (DDM) Support
These modules include DDM functionality, allowing real-time monitoring of critical transceiver parameters. Users can track:
Transmit/receive optical power
Temperature
Laser bias current
Supply voltage
This information aids in preventive maintenance and helps network administrators ensure reliable, efficient operations.
Durable Design for Harsh Environments
Built with a metal housing for EMI protection and heat dissipation, the modules are suited for rugged environments. Operating temperature ranges from -10°C to +70°C, making them reliable for both indoor and outdoor applications. Additionally, they offer low power consumption, ideal for energy-efficient network infrastructure.
