The GLC LH SM Datasheet is a crucial document for anyone working with network hardware, particularly in the realm of fiber optic communications. It contains detailed specifications and performance characteristics of the GLC-LH-SM Small Form-factor Pluggable (SFP) transceiver module, allowing network engineers and technicians to properly deploy, troubleshoot, and maintain network infrastructure.
Decoding the GLC LH SM Datasheet Technical Specifications
The GLC LH SM Datasheet is essentially a comprehensive guide to a specific type of SFP transceiver. An SFP transceiver is a compact, hot-pluggable module that connects network devices like switches and routers to fiber optic cables. The “GLC-LH-SM” designation itself provides key information. “GLC” typically indicates a Cisco product, “LH” stands for Long Haul, signifying its capability to transmit data over extended distances, and “SM” denotes Single-Mode fiber optic cable compatibility. These modules convert electrical signals from the network device into optical signals for transmission over fiber, and vice versa. Understanding the datasheet ensures optimal network performance and avoids compatibility issues.
The information contained within a GLC LH SM Datasheet typically includes the following:
- Wavelength: Specifies the light wavelength used for transmission (typically 1310 nm for GLC-LH-SM).
- Distance: Indicates the maximum supported distance over single-mode fiber (often up to 10 km).
- Data Rate: States the supported data rate (usually 1.25 Gbps for Gigabit Ethernet).
- Optical Power Budget: Provides details on the transmitter output power and receiver sensitivity.
- Operating Temperature Range: Defines the acceptable temperature range for reliable operation.
These datasheets are important for various reasons:
- Compatibility verification: Ensures the transceiver is compatible with the existing network infrastructure.
- Performance prediction: Helps predict the performance of the link based on fiber optic cable characteristics and distance.
- Troubleshooting: Aids in diagnosing and resolving network issues by providing key parameters for comparison.
The following table showcases essential aspects covered in a typical GLC LH SM Datasheet:
| Parameter | Description |
|---|---|
| Wavelength | 1310nm |
| Max Distance | 10 km |
| Data Rate | 1.25 Gbps |
