Introduction to GLC-LX-SMD optical module

Definition and background:
GLC-LX-SMD optical module is a small optical module used for optical fiber transmission. It belongs to one of the series of optical modules produced by Cisco Systems and is used to implement optical fiber connections in Cisco network equipment. The GLC-LX-SMD optical module has an LC connector and provides a high-performance optical fiber transmission solution.

Transmission distance and wavelength:
GLC-LX-SMD optical modules are usually used for short to medium distance optical fiber transmission. It supports a maximum transmission distance of 10 kilometers (6.2 miles). The module uses a fiber wavelength of 1310 nanometers for transmission.

Fiber wavelength refers to the wavelength of optical signals when they are transmitted in optical fibers. For the GLC-LX-SMD optical module, the wavelength it uses is 1310 nanometers. This wavelength is in the infrared region of the visible spectrum and is invisible to the human eye.

The working principle of GLC-LX-SMD optical module

Photoelectric conversion:
GLC-LX-SMD optical module realizes mutual conversion between optical signals and electrical signals through photoelectric conversion. It contains a light transmitter and a light receiver.

The optical transmitter is located at the sending end of the optical module. It receives electrical signals and converts them into optical signals. Typical light emitters use semiconductor lasers (such as laser diodes), which generate a laser beam by injecting an electric current. The laser beam is coupled into the optical fiber and becomes an optical signal.

The optical receiver is located at the receiving end of the optical module. It receives optical signals and converts them into electrical signals. A typical light receiver uses a photodiode or photodetector, which converts a light signal into an electrical current. After the current is amplified and processed, it becomes a digital electrical signal for processing and transmission in network equipment.

Optical fiber transmission:
GLC-LX-SMD optical module transmits data through optical fiber. Optical fiber is a flexible, transparent material with a high refractive index that can transmit optical signals along its length.

When a light signal enters an optical fiber, it travels through the fiber’s core. The fiber’s core is made of a high-refractive index material (usually glass or plastic) and is surrounded by a low-refractive index material (the cladding). Due to the difference in refractive index between the core and the cladding layer, the optical signal undergoes total internal reflection inside the fiber, thereby maintaining the transmission of the optical signal.

The refraction and reflection processes of optical fibers enable optical signals to be transmitted in optical fibers while reducing signal loss and interference. This enables the GLC-LX-SMD optical module to provide reliable data transmission in fiber optic transmission.

Characteristics and performance of GLC-LX-SMD optical module

Transmission rate:
GLC-LX-SMD optical modules have high transmission rates, typically 1 gigabits per second (Gbps). It supports high-speed data transmission and is suitable for network applications requiring higher bandwidth. This enables the GLC-LX-SMD optical module to handle the transmission of large amounts of data and support high-performance network connections.

Transmission distance:
GLC-LX-SMD optical module has a long transmission distance, generally up to 10 kilometers (6.2 miles). This makes it suitable for network connection needs that cover a larger area. The long transmission distance of the GLC-LX-SMD optical module allows it to provide reliable data transmission on network links spanning longer distances.

Single mode fiber:
GLC-LX-SMD optical module uses single-mode fiber for optical transmission. Single-mode fiber has a smaller mode of light, allowing the beam to travel along the core of the fiber. In contrast, multimode fiber has larger light modes, resulting in a wider propagation mode of the beam. Using single-mode fiber can reduce the dispersion and loss of optical signals and provide more stable and reliable transmission performance.

The features and performance of the GLC-LX-SMD optical module make it a reliable fiber optic transmission solution. It has high transmission rate and long transmission distance, and is suitable for applications requiring large bandwidth and long-distance transmission. At the same time, by using single-mode fiber, it can provide narrower beam transmission characteristics, improving the stability and reliability of transmission.
