H3C SFP-XG-LX-SM1310产品简介

Fiber modules are H3C SFP-XG-LX-SM1310 used for transmitting fiber signals over optical fibers. Fiber transmission features low loss and is fit for long distance transmission.
The H3C switches H3C SFP-XG-LX-SM1310 support various fiber modules of different specifications. You can select suitable fiber modules as needed for data transmission over optical fibers.
At present, the commonly H3C SFP-XG-LX-SM1310 used fiber modules are transceivers. They are mainly used for fiber-to-copper and copper-to-fiber conversions and provide H3C SFP-XG-LX-SM1310 the following functions: fiber power control, modulation transmission, signal probe, IV conversion, and limiting amplifier and decision regeneration. In addition, transceivers provide some other functions, such as counterfeit-prevention query and TX-disable. Common transceivers include SFP, XFP, SFP+, QSFP+, and CFP.H3C SFP-XG-LX-SM1310
Data rate H3C SFP-XG-LX-SM1310
Data rate is the number of bits transmitted per second. The unit of measure for data rate is Mbps or Gbps. The fiber modules available for the H3C switches mainly provide data rates of  H3C SFP-XG-LX-SM1310 100 Mbps, 1 Gbps, 10 Gbps, and 40 Gbps.
Transmission distance
For fiber modules, three types of transmission distances H3C SFP-XG-LX-SM1310 are available: short haul, middle reach, and long haul. Generally, a distance of 2 km (1.2 miles) is considered as short haul, 10 km (6.2 miles) to 20 km (12.4 miles) as middle reach, and 30 km (18.6 miles) and over as long haul.
Transmission H3C SFP-XG-LX-SM1310 distances provided by fiber modules are mainly limited by certain loss and dispersion suffered during the transmission of fiber signals over optical fibers.
·           Loss is the fiber energy H3C SFP-XG-LX-SM1310 loss due to the absorption, dispersion and leakage over the media when light travels through optical fibers. This loss increases in direct ratio to transmission distance.
·           Dispersion happens mainly because H3C SFP-XG-LX-SM1310 electromagnetic waves of different wavelengths travel at different rates over the same medium, causing different wave components of fiber signals to reach the receiving end early or late as the transmission distance increases, which in turn causes impulse broadening, making the signal values indistinguishable.
Therefore, choose suitable fiber modules according to actual networking conditions to meet different transmission distance requirements.
Central wavelength H3C SFP-XG-LX-SM1310
Central wavelength represents the wave band used for fiber signal transmission. At present, there are mainly three central wavelengths for common fiber modules: 850 nm, 1310 nm, and 1550 nm, respectively representing three wavebands.
·           The 850 nm wave H3C SFP-XG-LX-SM1310 band is mainly used for short-reach transmission.
·           The 1310 nm and 1550 nm wave bands are mainly used for middle- and long-reach transmission.
Fiber types H3C SFP-XG-LX-SM1310
Fiber mode H3C SFP-XG-LX-SM1310

Depending on the mode of light transmission in fibers, fibers fall into two types: single-mode and multimode.
·           Multimode H3C SFP-XG-LX-SM1310 fibers (MMFs) have thicker fiber cores and can transport light in multiple modes. However, the inter-mode dispersion is greater and worsens as the transmission distance increases.  Other factors that influence the transmission distance of multimode fibers include data rate, core diameter, and mode bandwidth. For moreH3C SFP-XG-LX-SM1310  information, see Table 2. Modal bandwidth is a measure of the highest frequency of signal a multimode fiber can support over a specific distance, expressed as MHz·km (multiplied).
