1.25 GBPS SM SF 20 km SC BIDI SFP Transceiver 1550/1310

1.25 Gbps SM SF 20 km SC BiDi SFP Transceiver 1550/1310nm – High-Performance Single-Fiber Networking Solution

The 1.25 Gbps Single-Mode Simplex SC BiDi SFP Transceiver (1550nm/1310nm) is an advanced, high-speed optical module designed for bidirectional data transmission over a single strand of fiber. It operates at a transmission wavelength of 1550nm and a receiving wavelength of 1310nm, making it ideal for use in Gigabit Ethernet, Fiber Channel, and other optical communication applications requiring reliable data transfer up to 20 kilometers.

Using Wavelength Division Multiplexing (WDM) technology, this transceiver enables simultaneous transmission and reception of signals on the same fiber, effectively halving fiber cabling requirements while maintaining performance and signal integrity.

Key Features

✅ 1.25 Gbps Data Transfer Rate

This SFP module supports data rates up to 1.25 Gbps, making it perfect for Gigabit Ethernet (1000BASE-BX) and other high-speed communication protocols. It delivers consistent, stable performance for enterprise networks, metropolitan area networks (MANs), and telecom backbone systems.

✅ Single-Mode Operation Over 20 km

Engineered for Single Mode Fiber (SMF), the module can achieve transmission distances of up to 20 kilometers. This makes it ideal for point-to-point long-distance links, connecting buildings, data centers, or network access points in large campuses or service provider networks.

✅ WDM BiDi Functionality (1550nm Tx / 1310nm Rx)

The transceiver uses WDM BiDi (Bidirectional) technology, operating with 1550nm wavelength for transmission and 1310nm for reception. This allows it to send and receive data on a single strand of fiber, effectively reducing fiber deployment costs by 50% while improving infrastructure efficiency.

✅ SC Connector Interface

The module features a simplex SC connector, which is easy to handle and widely used in telecommunications and data communication systems. It provides a secure, reliable connection with low insertion loss.

✅ Compact Hot-Pluggable Design

Fully compliant with the SFP Multi-Source Agreement (MSA) standards, this transceiver is hot-swappable, enabling network administrators to replace or upgrade modules without shutting down the network – ensuring minimal downtime.

✅ Low Power Consumption

With a power consumption of typically <1W, this transceiver is energy efficient, making it suitable for use in dense equipment environments like data centers or telecom central offices.

✅ Wide Compatibility

The SFP is compatible with most major OEM equipment and third-party networking hardware. It supports various switches, routers, media converters, and other devices with standard SFP ports.

✅ Optional Digital Diagnostic Monitoring (DDM)

Some versions support DDM/DOM functionality, offering real-time monitoring of operating parameters such as temperature, voltage, laser bias current, and optical output/input power – essential for proactive maintenance and system diagnostics.
