SFP MODULE 1.25G 60KM 1310+1490 SC SINGLE MODE (PAIR)-NETLINK

SFP Module 1.25G 60KM 1310+1490 SC Single Mode (Pair) – NETLINK                                              The NETLINK SFP Module 1.25G 60KM 1310+1490 SC Single Mode (Pair)  is a high-quality Small Form-factor Pluggable (SFP) transceiver solution designed for robust, long-distance fiber optic communication. Engineered for exceptional speed, reliability, and performance, this SFP module pair is ideal for telecom carriers, data centers, ISPs, and enterprise network environments requiring seamless connectivity over extended distances of up to 60 kilometers.

This paired SFP module supports 1.25Gbps data transmission and operates on wavelengths of 1310nm and 1490nm, enabling bidirectional (BiDi) communication over a single strand of single-mode fiber (SMF). The use of SC-type connectors ensures a secure and consistent optical interface.

Long-Distance Connectivity Over Single Fiber

The NETLINK 1.25G SFP module pair is designed to support single-mode fiber transmission up to 60KM, making it a cost-effective and space-saving solution for long-distance point-to-point network links. By utilizing Wavelength Division Multiplexing (WDM) technology—transmitting and receiving over two different wavelengths (1310nm and 1490nm)—these modules significantly reduce fiber cabling needs while maintaining full-duplex data transmission.

This makes them perfect for rural broadband, metro access networks, FTTH systems, and long-distance backbone infrastructures.

Paired SFP for Seamless BiDi Communication

Each module in the pair is engineered to complement the other, with one transmitting at 1310nm and receiving at 1490nm, and the other doing the opposite. This bi-directional transmission over a single optical fiber enhances bandwidth utilization and lowers deployment costs without sacrificing speed or performance.

By reducing the need for dual fiber runs, these modules offer simplified cabling, easier installation, and a more organized infrastructure.

High-Speed Data Transfer

With data transfer rates of up to 1.25Gbps, these SFP modules are suitable for Gigabit Ethernet, Fast Ethernet, and fiber channel applications. They are widely used in:

• Telecom networks

• Data centers

• Enterprise backbones

• Optical switches and routers

• Media converters and access equipment

Their compliance with industry-standard SFP MSA (Multi-Source Agreement) ensures broad compatibility with various brands and platforms, making integration into existing networks quick and trouble-free.

Built-In Digital Diagnostics

The NETLINK 1.25G SFP pair supports Digital Diagnostic Monitoring (DDM), providing real-time data such as:

• Optical input/output power

• Temperature

• Supply voltage

• Laser bias current

These features help network engineers perform proactive maintenance, detect performance degradation, and ensure network health and uptime.

Durable Build and Wide Compatibility

Built to last, the modules are enclosed in a sturdy metallic housing that provides electromagnetic interference (EMI) shielding and superior heat dissipation. With SC connectors, these modules offer easy plug-and-play installation and a secure fit in any compatible SFP port.

They support a wide operating temperature range (typically from -10°C to +70°C), making them suitable for both indoor and outdoor deployments in harsh environments.
