1.The numbers given for multimode fiber-optic cable refer to the core diameter. For single-mode fiber-optic cable,

8.3 microns refers to the core diameter. The 9-micron and 10-micron values refer to the mode-field diameter (MFD), which is the diameter of the light-carrying portion of the fiber. This area consists of the fiber core plus a small portion of the surrounding cladding. The MFD is a function of the core diameter, the wavelength of the laser, and the refractive index difference between the core and the cladding.

2.Use with MMF only.

3.When using an LX/LH GBIC with 62.5-micron diameter MMF, you must install a mode-conditioning patch cord (CAB-GELX-625 or equivalent) between the GBIC and the MMF cable on both the transmit and receive ends of the link. The mode-conditioning patch cord is required for link distances less than 328 feet (100 m) or greater than 984 feet (300 m). The mode-conditioning patch cord prevents overdriving the receiver for short lengths of MMF and reduces differential mode delay for long lengths of MMF.

4.Requires dispersion-shifted single-mode fiber-optic cable.

Note The mode-conditioning patch cord (CAB-GELX-625 or equivalent) is required to comply with IEEE standards. The IEEE found that link distances could not be met with certain types of fiber-optic cable cores. The solution is to launch light from the laser at a precise offset from the center by using the mode-conditioning patch cord. At the output of the patch cord, the LX/LH GBIC is compliant with the IEEE 802.3z standard for 1000BASE-LX.

WS-G5484, WS-G5487, WS-G5486 specifications

Cisco Systems is a renowned leader in networking technology, offering a wide array of products designed to meet the growing demands of modern network infrastructure. Among its extensive portfolio, the WS-G5484, WS-G5486, and WS-G5487 series of line cards stand out for their robust features and exceptional performance, catering specifically to the needs of service providers and large enterprise networks.

The Cisco WS-G5484 is a 48-port 10/100 Fast Ethernet switching module. Its primary purpose is to provide high-density Ethernet connectivity in a modular switch architecture. This line card supports a variety of features such as Cisco's VLAN segmentation, enabling network administrators to efficiently segregate traffic and enhance security. It is designed for ease of use, offering plug-and-play capabilities and seamless integration into existing network infrastructures.

Meanwhile, the WS-G5486 is a more advanced line card that incorporates both Ethernet and uplink services. This model features 48 ports of 10/100/1000 Mbps Ethernet, allowing for a combination of Fast and Gigabit Ethernet connections in a single module. One of the key characteristics of the WS-G5486 is its support for Power over Ethernet (PoE), which enables it to supply power to connected devices like IP phones, wireless access points, and security cameras, thus simplifying deployment and reducing the need for additional power sources.

In addition to the above models, the WS-G5487 further enhances the capability of Cisco's switching solutions. It is designed as a 10 Gigabit Ethernet line card that features four 10G SFP+ ports. This card is particularly well-suited for high-speed data centers and backbone networks, offering exceptional bandwidth to accommodate demanding applications. The WS-G5487 supports advanced features such as Virtual Routing and Forwarding (VRF), which allows for efficient traffic management and better resource utilization.

All three line cards operate on Cisco's IOS software, which provides robust features like Layer 2 and Layer 3 switching, advanced security protocols, and comprehensive network management tools. This software backbone ensures that these devices are not only reliable but also capable of scalable solutions as network demands evolve.

Together, the WS-G5484, WS-G5486, and WS-G5487 represent a powerful trio of line cards that provide network professionals with scalable, flexible, and high-performance connectivity solutions, meeting the diverse needs of evolving network environments.
