10GE SFP+ optical module types

Single mode optical module:
The 10GE SFP+ single-mode optical module is an optical module suitable for single-mode optical fiber transmission. It has the following characteristics:

  1. Working distance: Single-mode optical modules are suitable for long-distance transmission requirements. Usually, the transmission distance it supports can reach tens of kilometers or even further. This makes single-mode optical modules very useful in network connections that need to span larger distances, such as long-distance communications between data centers or long-distance enterprise network links.

  2. Fiber type: Single-mode optical modules mainly use single-mode optical fibers for transmission. Single-mode fiber has a smaller core diameter and can support the transmission of a single optical mode, thereby reducing the transmission loss and dispersion effect of optical signals. This enables single-mode optical modules to achieve longer transmission distances and higher transmission quality.

  3. Applicable scenarios: Single-mode optical modules are suitable for scenarios requiring long-distance transmission, low loss and high transmission quality. It is commonly used in applications such as cross-regional data center interconnection, remote server connections, and enterprise networks that need to cover a large area.

Multimode optical module:
The 10GE SFP+ multi-mode optical module is an optical module suitable for multi-mode optical fiber transmission. It has the following characteristics:

  1. Working distance: Multi-mode optical modules are suitable for short-distance transmission requirements. Usually, the transmission distance it supports is within a few hundred meters. This makes multi-mode optical modules very suitable for short-distance connections in local area network (LAN) environments, such as server interconnections within enterprises, links between switches, etc.

  2. Fiber type: Multimode optical modules use multimode optical fibers for transmission. Multimode fiber has a larger core diameter and is capable of transmitting multiple light modes simultaneously. Although multimode fiber has a relatively short transmission distance, it provides cost-effectiveness and flexibility for short-distance transmission needs.

  3. Applicable scenarios: Multi-mode optical modules are suitable for short-distance transmission requirements, especially in LAN environments. It is commonly used in scenarios such as server interconnection within enterprises, device connections within data centers, and switch links in computer rooms.

It should be noted that the fiber types and transmission distances between single-mode optical modules and multi-mode optical modules are not interoperable. When selecting a 10GE SFP+ optical module, you need to select the appropriate optical module type based on the specific transmission distance and fiber type requirements.

LC interfaces are widely used in high-density applications such as data centers and enterprise networks.

  2. SC (Standard Connector) interface: The SC interface is another common 10GE SFP+ slot interface type. It is also a miniaturized connector with bidirectional transmission capabilities and is suitable for single-mode optical fiber and multi-mode optical fiber. The SC interface was widely used in network equipment and optical fiber communication systems in the past, but has been gradually replaced by the LC interface in some environments.

  3. MPO (Multi-fiber Push-On) interface: The MPO interface is a multi-fiber slot interface used to support multi-mode optical fiber transmission. It uses multi-core connectors that can transmit multiple fiber channels simultaneously. MPO interfaces are useful in high-density applications such as data centers and high-speed Fiber Channel connections.

It should be noted that the slot interface type may vary depending on the device and manufacturer. When selecting a 10GE SFP+ optical module, you need to ensure that its slot interface matches the slot interface type of the required device to ensure correct connection and compatibility.
