GB100SM SFP Module | 1000Base, 1550nm, LC, SM, 100km

1000Base SFP Module for 100km Singlemode Fiber

The VERSITRON GB100SM is a long-distance 1000Base SFP module designed to provide reliable Gigabit Ethernet transmission over singlemode fiber. With a maximum rated distance of 100 kilometers, it is well suited for network connections that extend far beyond the reach of conventional copper Ethernet.

Operating at 1550nm, the GB100SM uses an LC fiber connector and is designed for integration with compatible SFP-enabled networking equipment. Its extended fiber reach makes it particularly useful for backbone and inter-building connections where reliable long-distance Gigabit Ethernet connectivity is required.

The VERSITRON SFP datasheet specifies the GB100SM for 1000Mbps operation over 100km of singlemode fiber, with a transmit power range of 0 to +5 dBm, receive sensitivity below -30 dBm, and an operating temperature range of 0°C to 70°C.

Extend Gigabit Ethernet Up to 100km

The GB100SM allows network designers to extend Gigabit Ethernet connectivity across long distances using existing singlemode fiber infrastructure.

A 100km SFP can be useful when network equipment is separated by substantial distances, including connections between:

• Network buildings
• Campus facilities
• Remote communications sites
• Telecommunications locations
• Enterprise network facilities
• Fiber network aggregation points
• Long-distance Ethernet backbone connections

Rather than replacing an entire network architecture, a compatible SFP module can provide the fiber interface needed to extend connectivity over an existing singlemode fiber link.

1550nm Singlemode Fiber Technology

The GB100SM operates at 1550nm over singlemode fiber, a combination commonly used for extended-reach fiber communications.

The module is designed for 100km transmission, providing substantially greater reach than VERSITRON's shorter-distance Gigabit SFP models. This makes the GB100SM a logical choice when a network requires long-distance fiber connectivity and the available fiber infrastructure is singlemode.

GB100SM Technical Specifications

These specifications are taken directly from the VERSITRON Fiber Optic SFP Modules datasheet.

Industry-Standard SFP Design

The GB100SM uses an industry-standard Small Form Pluggable (SFP) form factor, providing a convenient and modular way to add fiber connectivity to compatible networking equipment.

VERSITRON's SFP modules feature:

• Industry-standard SFP design
• LC fiber connectors
• Differential LVPECL inputs and outputs
• 3.3V single power supply
• TTL signal detect indicator
• Hot-pluggable installation
• Class 1 laser compliant with EN 60825-1

This modular design allows network administrators to select an SFP based on the required speed, fiber type, wavelength, connector, and transmission distance.

Comparing VERSITRON Gigabit SFP Distances

VERSITRON offers a range of 1000Base SFP modules for different network distances. The product datasheet includes singlemode Gigabit models ranging from 10km through 100km, along with complementary-wavelength options for 10km, 20km, 40km, 60km, and 80km applications.

For applications requiring the longest standard singlemode reach in this product family, the GB100SM provides up to 100km at 1550nm.

Typical Applications

Extend Gigabit Ethernet between network locations separated by long distances using singlemode fiber.

Provide high-speed fiber connectivity between telecommunications facilities and network infrastructure.

Connect buildings and remote facilities where distances exceed the practical limits of copper Ethernet.

Support long-distance connections between network aggregation points, facilities, and remote locations.

Add long-distance Gigabit fiber connectivity to compatible SFP-enabled switches, media converters, and other network equipment.

Extend Ethernet services to remote network locations using existing singlemode fiber infrastructure.

How to Select the Right Gigabit SFP

Selecting the correct SFP requires matching the module to the equipment and fiber infrastructure being used. Consider:

• Data rate: The GB100SM operates at 1000Mbps.
• Fiber type: The GB100SM is designed for singlemode fiber.
• Wavelength: The module operates at 1550nm.
• Transmission distance: The GB100SM is rated for distances up to 100km.
• Connector: The module uses an LC fiber connector.
• Equipment compatibility: Confirm that the connected switch, media converter, or other networking equipment supports the required SFP specification.

For applications requiring a 100km Gigabit Ethernet connection over singlemode fiber, the GB100SM is the appropriate VERSITRON model in this product family.
