SFP Module Dell 1000Base-LX Long Haul 01-SSC-9790 — Gigabit fiber transceiver, single-mode

The Dell SFP Module 1000Base-LX Long Haul is a gigabit small-form pluggable (SFP) fiber transceiver designed for long-distance single-mode fiber connections. It provides 1000 Mbps Ethernet transport over single-mode fiber and is intended for backbone links, campus distribution, and data center uplinks. The module's hot-pluggable design allows installation or replacement without powering down compatible network equipment, enabling straightforward expansion or maintenance of fiber networks.

Advantages

This SFP module supports long-reach single-mode links, offering stable gigabit throughput for extended distances required by interbuilding and metropolitan connections. The transceiver's compact SFP form factor conserves space in fiber ports and is compatible with a range of switches and routers that accept standard 1000Base-LX modules. Low power consumption and reliable optical performance help maintain consistent link quality and reduce operating costs in continuous-use environments.

Suitable for

• Backbone fiber links between buildings on a campus
• Data center uplinks and server aggregation
• Long-distance single-mode fiber runs in metropolitan or enterprise networks
• Replacing or expanding existing Gigabit fiber interfaces

Key specifications

• Interface: SFP (Small Form-factor Pluggable)
• Data rate: 1000 Mbps (Gigabit Ethernet)
• Fiber type: Single-mode fiber
• Wavelength: Long-wavelength (LX) optical transmission
• Distance capability: Designed for long-haul single-mode links (extended reach)
• Connector type: Standard fiber optical connector (LC-style compatible)
• Hot-pluggable: Yes
• Typical power consumption: Low-power SFP-class transceiver

How to use

Insert the SFP module into a compatible SFP port on a switch, router or other network device while the device is powered on, observing the correct orientation until the module seats securely. Connect a single-mode fiber patch cable with the appropriate LC-style connectors to the optical port, ensuring proper transmit/receive alignment. Configure the network equipment as needed for a 1000Base-LX interface; most devices will auto-negotiate the Gigabit Ethernet link once the optical connection is established. Monitor link status and signal indicators on the host device to verify a stable connection.

Recommendations

Use single-mode fiber rated for long-distance transmission and quality LC connectors to achieve expected reach and performance. Avoid bending the fiber beyond its minimum bend radius and keep connectors clean to prevent signal loss. Verify compatibility with your network equipment's SFP compatibility list if vendor locking is a concern, and test links after installation to confirm expected throughput and error rates.
