10Gb Ethernet SFP Module for 40km Singlemode Fiber

The VERSITRON 10GB40SM is a 10Gb Ethernet SFP module designed for high-speed, long-distance fiber optic networking. Operating at a 1550nm wavelength over singlemode fiber, it supports transmission distances of up to 40 kilometers.

This extended reach makes the 10GB40SM particularly useful for connecting network locations that are too far apart for short-reach multimode fiber, while maintaining 10Gbps connectivity over a singlemode fiber infrastructure.

Long-Distance 10Gb Fiber Connectivity

High-bandwidth networks often need to connect switches, data centers, campuses, buildings, and other network locations across significant distances. The 10GB40SM provides a 10Gbps optical connection designed specifically for these longer-distance requirements.

Its 1550nm singlemode optical interface supports up to 40km, providing substantially greater reach than short-distance 10Gb multimode modules.

For example, VERSITRON's 10GBMM supports multimode fiber distances up to 300m, while the 10GB10SM supports 10km over singlemode fiber. The 10GB40SM extends that capability to 40km.

Designed for High-Bandwidth Network Backbones

The 10GB40SM provides the bandwidth and fiber reach needed for applications where large amounts of data must move reliably between network locations.

10Gb Ethernet can support high-throughput applications including data center connectivity, network aggregation, telecommunications infrastructure, and other backbone connections.

The module uses an LC fiber connector, is hot-pluggable, and operates from a single 3.3V power supply. VERSITRON's SFP modules also include a TTL signal detect indicator and use Class 1 laser technology compliant with EN 60825-1.

Typical Applications

The 10GB40SM is well suited for:

Enterprise Network Backbones – Connect network switches and aggregation equipment over extended fiber distances.
Data Center Interconnects – Provide high-speed fiber connectivity between network locations.
Campus Networks – Connect buildings and facilities across larger campuses.
Telecommunications Networks – Extend compatible 10Gb Ethernet connections over singlemode fiber.
Long-Distance Network Extensions – Connect remote network equipment across distances up to 40km.
High-Bandwidth Applications – Support applications requiring high-speed data transmission.
Government and Institutional Networks – Provide long-distance fiber connectivity between facilities.
Security and Surveillance Infrastructure – Support high-bandwidth fiber connections for networked video systems.

Choosing the Right 10Gb SFP Module

VERSITRON offers several 10Gb fiber optic SFP options for different network distances and fiber types:

Model	Wavelength	Fiber	Distance
10GBMM	850nm	Multimode	Up to 300m*
10GB10SM	1310nm	Singlemode	10km
10GB40SM	1550nm	Singlemode	40km
10GB80SM	1550nm	Singlemode	80km

*The 10GBMM distance varies by multimode fiber type, with up to 300m over OM3.

This makes the 10GB40SM a strong choice when 10Gbps bandwidth and 40km singlemode fiber reach are the primary requirements.
