155M SFP Series

What are the performance indicators of the 155M Optical Transceiver Series? How to evaluate its performance?

The performance indicators of 155M Optical Transceiver Series mainly include the following aspects:

Transmission rate: This is one of the most basic parameters for measuring transceiver performance, usually measured in Mbps (Megabits per second). For the 155M Optical Transceiver Series, its transmission rate should be close to or reach 155Mbps.

Transmission distance: The transmission distance of a transceiver refers to the maximum distance that a signal can be transmitted while maintaining sufficient quality. Different transceiver designs target different transmission distances, depending on factors such as the type of fiber they use, their optical power budget, and receiver sensitivity.

Optical power: including transmit power and receiving sensitivity. Transmit power refers to the intensity of the optical signal emitted by the transceiver, while receiving sensitivity refers to the minimum optical signal intensity that the transceiver can detect. These two together determine the signal transmission capability of the transceiver.

Wavelength: The wavelength of light used by an optical transceiver is a critical parameter that is often selected for a specific fiber optic communications system. Common wavelengths are 850nm, 1310nm and 1550nm.

Bit Error Rate (BER, Bit Error Rate): Bit Error Rate is a measure of the ratio of the number of bits that have errors during the transmission process of the transceiver to the total number of bits. Low bit error rate means higher transmission quality and less signal distortion.

Jitter and Wander: These parameters describe the instability of a signal in the time domain and are critical for digital communications. Jitter refers to the change in signal edge position, while drift refers to the change in the average level of the signal.

Operating temperature range: The operating temperature range of the transceiver is also an important indicator for evaluating its performance. The wider operating temperature range means the transceiver can operate stably in more environmental conditions.

Electromagnetic compatibility (EMC) and electromagnetic interference (EMI): These indicators describe the stability of the transceiver in the electromagnetic environment and the degree of interference to other equipment.

When evaluating the performance of the 155M Optical Transceiver Series, it is usually necessary to comprehensively consider the above performance indicators. In practical applications, the evaluation of performance also involves the degree of matching with specific application requirements, such as system bandwidth requirements, transmission distance requirements, cost budget, etc. In addition, factors such as the reliability, durability and after-sales service of the transceiver also need to be considered.

What key factors need to be paid attention to when deploying and maintaining the 155M Optical Transceiver Series?

Here are some key factors to note when deploying and maintaining the 155M Optical Transceiver Series:

Compatibility: Ensure that the transceiver is compatible with existing optical fiber network equipment and systems, including interface type, wavelength, transmission rate, etc. Transceivers from different manufacturers or models may have different specifications and parameters, so matching and verification are required.

Fiber type and connection: Select the appropriate fiber type (such as single-mode or multi-mode) and the correct connector type (such as SC, LC, FC, etc.) to ensure the quality and stability of the fiber connection. At the same time, you need to pay attention to the cleanliness of the optical fiber to avoid the impact of dust and dirt on the optical signal.

Optical power management: Reasonably adjust the transmit power of the transceiver to avoid optical fiber damage caused by too high optical power or signal quality degradation caused by too low optical power. At the same time, monitor the optical power level of the receiver to ensure it is within the normal operating range.

Temperature and environment: Pay attention to the temperature range of the transceiver's working environment to avoid the impact of overheating or overcooling on device performance. In addition, the impact of environmental factors such as humidity and dust on the stability and life of the equipment needs to be considered.

Power and power supply: Ensure that the transceiver receives a stable and reliable power supply to avoid the impact of power fluctuations or interruptions on the operation of the equipment. At the same time, you need to pay attention to the matching and safety of the power interface.

Configuration and monitoring: Correctly configure transceiver parameters such as baud rate, data format, etc. to meet system requirements. At the same time, a monitoring mechanism is established to monitor the status, performance and fault information of the transceiver in real time so that problems can be discovered and solved in a timely manner.

Backup and replacement: Considering the possible failure or damage of the equipment, backup transceivers should be prepared to ensure the continuous operation of the system. Additionally, become familiar with the replacement and upgrade process so you can quickly replace failed equipment or upgrade to better performing transceivers if necessary.

Safety and Compliance: Comply with relevant safety regulations and standards to ensure that the installation, operation and maintenance of equipment meet safety requirements. At the same time, ensure that the equipment complies with local regulations and standards to avoid risks caused by illegal use.
