The SFP+ 10G-ER optical module is a high-speed optical module that is widely used in long-distance optical fiber transmission to provide users with stable and reliable data communication.

Overview of SFP+ 10G-ER optical module

The SFP+ 10G-ER optical module is a small pluggable module for fiber optic communications that supports 10 Gigabit Ethernet (10GbE) rates and long-distance transmission. It is based on the SFP+ (Small Form-Factor Pluggable Plus) standard and is one of the SFP+ series modules.

SFP+ 10G-ER optical module plays an important role in network communications. It provides high-bandwidth and high-rate data transmission and is suitable for scenarios requiring long-distance transmission. The optical module uses optical fiber media to transmit data and transmit information from one device to another through light to achieve reliable data communication.

SFP+ 10G-ER optical modules have a wide range of application scenarios in optical fiber transmission across long distances, including cross-city data center interconnection, campus network connections, wide area network connections, and optical fiber backbone networks of telecom operators. It provides high-speed, long-distance data transmission capabilities for these applications, ensuring data reliability and stability.

The working principle of SFP+ 10G-ER optical module

The working principle of the SFP+ 10G-ER optical module involves processes such as photoelectric conversion and signal modulation. Here’s an overview of how it basically works:

  1. Photoelectric conversion: SFP+ 10G-ER optical module first converts electrical signals into optical signals. It uses a pair of photoelectric converters, a laser and an optical receiver. Lasers convert electrical signals into optical signals, which are transmitted through optical fibers. Optical receivers receive optical signals and convert them back into electrical signals.

  2. Signal modulation: At the transmitting end, the electrical signal is converted into an optical signal through a modulation process. This is usually accomplished using direct modulation or external modulation. Direct modulation refers to modulating the electrical signal directly into the laser, while external modulation modulates the electrical signal into an external modulator (such as a Mach-Zehnder modulator) and then inputs it into the laser.

  3. Optical signal transmission: Optical signals are transmitted through optical fibers. SFP+ 10G-ER optical module supports long-distance transmission and usually uses single-mode optical fiber for transmission. Single-mode fiber has a smaller core diameter, which can reduce the propagation loss and dispersion of optical signals, thereby supporting long-distance transmission.

  4. Optical signal reception: At the receiving end, the optical signal is received by the optical receiver. Optical receivers convert optical signals into electrical signals, amplify and process them. The electrical signal is then sent to a receiving device for further processing and decoding.

The SFP+ 10G-ER optical module achieves high-speed, long-distance data transmission mainly based on the following technologies and features:

  1. High rate: SFP+ 10G-ER optical module supports 10GbE rate and provides high-bandwidth data transmission capabilities. This enables it to transfer large amounts of data in a shorter period of time.

  2. High-power laser: In order to achieve long-distance transmission, the SFP+ 10G-ER optical module uses a high-power laser to generate strong light signals. This can provide enough optical power to overcome losses and attenuation in fiber transmission.

  3. Optical fiber transmission technology: SFP+ 10G-ER optical module usually uses single-mode optical fiber for transmission. Single-mode fiber has a smaller core diameter that reduces transmission loss and dispersion, allowing for long-distance transmission.

  4. Optical receiver sensitivity: In order to receive optical signals transmitted over long distances, the optical receiver of the SFP+ 10G-ER optical module has high sensitivity. This can improve signal reception and reduce the bit error rate in signal transmission.
