1G SFP Module Options

VERSITRON offers 1G SFP modules for a wide range of fiber optic network requirements. Standard duplex SFPs are available for multimode and singlemode fiber, while BiDi SFPs allow bidirectional communication over a single optical fiber.

Standard 1G Multimode SFP Modules

Standard multimode SFP modules are designed for shorter-distance Gigabit Ethernet connections using multimode fiber. Depending on the fiber type and module, available transmission distances range from several hundred meters to several kilometers.

Standard 1G Singlemode SFP Modules

Singlemode SFP modules provide longer-distance Gigabit Ethernet transmission and are available in configurations supporting distances from 10 kilometers to 100 kilometers. These modules are suited for campus backbones, telecommunications infrastructure, industrial networks, and other applications requiring extended fiber distances.

1G SFP Module Comparison

*Transmission distance for GBMM varies by multimode fiber type. Consult the product specifications for the applicable fiber-distance rating.

1G BiDi SFP Modules

VERSITRON also offers BiDi, or bidirectional, 1G SFP modules for applications where only one optical fiber is available. BiDi SFPs use different transmit and receive wavelengths, allowing two-way communication over a single strand of fiber.

BiDi modules are installed as complementary pairs. For example, one module may transmit at 1310nm and receive at 1550nm, while the corresponding module reverses those wavelengths. This allows a single fiber to carry both directions of the Gigabit Ethernet connection.

BiDi options are available for transmission distances of 10, 20, 40, 60, and 80 kilometers.

1G BiDi SFP Modules

Note: BiDi SFPs operate as matched A/B pairs. The complementary wavelength configuration allows both transmit and receive signals to travel over a single fiber strand. The product specifications and model lineup above are based on the VERSITRON SFP datasheet.
