Design and Architecture

The SFP-GE-L is a small form-factor pluggable (SFP) transceiver designed and manufactured by Cisco Systems. It is a single-mode fiber transceiver with a maximum data transfer rate of 1 Gbps and uses an LC connector.

The SFP-GE-L is designed to work with a wide range of Cisco networking devices, including routers, switches, and firewalls, that have an SFP port. It is hot-swappable, which means that it can be replaced while the device is still powered on, without disrupting network traffic.

The architecture of the SFP-GE-L is based on industry-standard specifications, including the Multi-Source Agreement (MSA) and the Small Form-factor Pluggable (SFP) specification. This makes it compatible with a wide range of networking equipment from different vendors, ensuring interoperability and ease of use.

The SFP-GE-L uses a Class 1 laser transmitter and a PIN photodiode receiver to transmit and receive data over single-mode fiber optic cables. It operates at a wavelength of 1310 nm, which is commonly used for long-distance communication over single-mode fiber.

The design of the SFP-GE-L is compact, with dimensions of 8.5 mm x 13.4 mm x 56.5 mm, allowing it to fit into small spaces and providing flexibility in network design. The LC connector is a standard fiber optic connector that provides a secure and reliable connection to the fiber optic cable.

The SFP-GE-L also supports Digital Optical Monitoring (DOM), which allows real-time monitoring of the transceiver's operating conditions, including temperature, voltage, and optical power levels. This information can be used to optimize network performance and detect potential problems before they occur.

Features and Benefits

The SFP-GE-L is a single-mode LC connector SFP transceiver manufactured by Cisco that supports data rates of up to 1 Gbps. It is designed for use with Cisco networking equipment, such as switches and routers, that support SFP interfaces. The SFP-GE-L offers several features and benefits, including:

  • Small Form-Factor Pluggable (SFP) design: The SFP-GE-L has a small form factor that allows for flexible and easy installation and removal of the transceiver module. This design feature provides flexibility for network administrators to add, remove or replace the transceiver without having to take down the entire network or switch.
  • Gigabit Ethernet connectivity: The SFP-GE-L supports data rates of up to 1 Gbps, which makes it ideal for high-speed network connectivity. It can be used for both short- and long-distance network links and is suitable for both LAN and WAN applications.
  • Single-mode fiber support: The SFP-GE-L supports single-mode fiber optic cables, which provide long-range connectivity up to 10 km. This makes it an ideal choice for network connections that span longer distances.
  • LC connector: The SFP-GE-L has an LC connector that provides a secure and reliable fiber optic connection. LC connectors are easy to install and maintain, and they provide low insertion loss and high return loss.
  • Digital Optical Monitoring (DOM) support: The SFP-GE-L supports DOM, which enables real-time monitoring of the transceiver's optical performance parameters, such as power level, temperature, and signal quality. This feature allows network administrators to proactively detect and address issues before they cause network downtime.
  • Cisco quality and compatibility: The SFP-GE-L is manufactured by Cisco, which ensures high-quality and reliable performance. It is also fully compatible with Cisco networking equipment, which ensures seamless integration and interoperability with existing network infrastructure.


The SFP-GE-L Cisco 1 GBPS Single-Mode LC Connector SFP Transceiver is a small form-factor pluggable (SFP) optical transceiver that provides high-speed connectivity in networking devices. Here are some advantages of using this transceiver:

  • High-speed connectivity: The SFP-GE-L transceiver provides 1 Gbps data transmission speed, which allows for faster data transfer and improved network performance.
  • Single-mode fiber compatibility: The SFP-GE-L transceiver is designed for use with single-mode fiber optic cables, which can transmit data over longer distances than multimode fibers. This makes it an ideal choice for long-distance network connections.
  • Hot-swappable: The SFP-GE-L transceiver is hot-swappable, which means it can be inserted and removed while the networking device is still running. This allows for easier maintenance and upgrades without disrupting network operations.
  • Flexibility: The SFP-GE-L transceiver can be used with a wide range of Cisco networking devices, including switches, routers, and firewalls. This makes it a versatile option for various networking environments.
  • Scalability: The SFP-GE-L transceiver can be used to expand the network capacity by adding more network connections. This allows for easy network scalability as the business grows.
  • Cost-effective: The SFP-GE-L transceiver is a cost-effective solution for high-speed networking. It eliminates the need for expensive and bulky optical modules, making it an affordable option for businesses of all sizes.
