1000Base SFP Module for 60km Singlemode Fiber

The VERSITRON GB60SFB is a 1000Base SFP module designed to extend Gigabit Ethernet connectivity over singlemode fiber distances up to 60 kilometers.

The module uses 1550nm for transmission and 1310nm for reception, providing complementary wavelength operation with the GB60SFA. This configuration is well suited for long-distance fiber links where network equipment needs to communicate over a singlemode fiber connection while maintaining Gigabit Ethernet performance.

The VERSITRON Fiber Optic SFP Modules datasheet specifies the GB60SFB at 1000Mbps, 1550nm Tx, 1310nm Rx, singlemode fiber, 60km, and LC connectivity.

Long-Distance 1Gbps Fiber Connectivity

The GB60SFB combines Gigabit Ethernet performance with a 60km singlemode fiber reach, making it an effective solution for extending network connectivity between locations that are beyond the practical reach of standard copper Ethernet or shorter-distance multimode fiber.

The LC connector provides a compact fiber interface for compatible SFP-enabled network switches, media converters, and other networking equipment.

With a 0–70°C operating temperature range, the GB60SFB is designed for reliable operation across a variety of indoor network environments.

GB60SFA and GB60SFB: Complementary 60km SFP Modules

The GB60SFA and GB60SFB are complementary wavelength SFP modules designed to work together for long-distance fiber connectivity.

The VERSITRON datasheet lists the GB60SFA and GB60SFB as complementary 1000Mbps modules with the same 60km singlemode fiber distance and LC connector, while their transmit and receive wavelengths are reversed.

For a complementary wavelength link, install the GB60SFA at one end and GB60SFB at the opposite end. This allows the two modules to transmit and receive using the corresponding wavelengths.

GB60SFB Technical Specifications

These specifications are based on the VERSITRON Fiber Optic SFP Modules datasheet.

Typical Applications

The GB60SFB is designed for applications requiring reliable Gigabit Ethernet connectivity over extended singlemode fiber distances.

• Network Backbones – Extend Gigabit Ethernet between network locations over long-distance fiber.
• Telecommunications – Support long-distance fiber optic infrastructure and network connections.
• Campus Networks – Connect buildings and remote facilities using singlemode fiber.
• Enterprise Networks – Extend high-speed connectivity between geographically separated network locations.
• Government Networks – Provide long-distance fiber connectivity between facilities and network infrastructure.
• Industrial Networks – Connect remote industrial network equipment using fiber optic cabling.
• Security and Surveillance Networks – Extend network connectivity to remote surveillance infrastructure where long-distance fiber is required.

Industry-Standard SFP Design

The GB60SFB uses an industry-standard Small Form Pluggable (SFP) form factor with an LC fiber connector. VERSITRON's SFP modules feature hot-pluggable operation, a single 3.3V power supply, TTL signal detection, and differential LVPECL inputs and outputs.

The module also incorporates a Class 1 laser compliant with EN 60825-1.

Choose the Right VERSITRON Gigabit SFP

VERSITRON offers a broad selection of 1000Mbps SFP modules for different fiber types, wavelengths, and transmission distances.

The product family includes multimode and singlemode options, with singlemode Gigabit modules available for distances ranging from 10km through 100km, as well as complementary wavelength modules for long-distance fiber applications.

When selecting an SFP module, consider:

• Data rate – 100Mbps, 1000Mbps, or 10Gbps
• Fiber type – Multimode or singlemode
• Transmission distance – Select a module appropriate for the required fiber link
• Wavelength – Match the wavelength requirements of the network
• Connector type – The VERSITRON SFP family uses LC fiber connectors
• Complementary module – For wavelength-specific applications, verify that the SFP at the opposite end has the appropriate complementary transmit and receive wavelengths

For a 60km complementary wavelength application:

• GB60SFA: 1310nm Tx / 1550nm Rx
• GB60SFB: 1550nm Tx / 1310nm Rx
