It seems there might be a bit of confusion in the terminology. Transceivers, such as SFP (Small Form-Factor Pluggable) modules, typically use different types of connectors, and LC and SC are examples of these connectors. However, the terms "LC transceiver" and "SC transceiver" can be a bit misleading.

Here's the clarification:

1. LC and SC Connectors:

• LC Connector: LC connectors are small form-factor connectors commonly used in fiber optic connections. They have a push-pull design and are known for their compact size. LC connectors are widely used in SFP and SFP+ transceivers, among other applications.

• SC Connector: SC connectors are another type of fiber optic connector that uses a push-pull coupling mechanism. They are larger than LC connectors and were more common in older generations of transceivers, such as some types of Gigabit Ethernet transceivers.

2. Transceivers and Connectors:

• When referring to transceivers, such as SFP or SFP+ modules, it's more accurate to mention the type of connector they use rather than labeling them as "LC transceivers" or "SC transceivers."

• SFP and SFP+ transceivers can be equipped with LC connectors, SC connectors, or other types, depending on the specific design and application.

3. Usage:

• LC connectors are more prevalent in modern SFP and SFP+ transceivers due to their compact size, making them suitable for high-density applications in data centers.

• SC connectors were more common in earlier networking equipment, but LC connectors have become the standard for higher-speed and compact applications.

In summary, the key is to refer to the type of connector used by the transceiver (e.g., LC or SC) rather than using terms like "LC transceiver" or "SC transceiver." The choice of connector is often based on factors such as the desired port density, application requirements, and industry standards.
