    Fan Modules | 24 EX4300 Switch Components | 25 Juniper Networks EX4300 Ethernet Switches provide connectivity for high-density environments and scalability for growing networks. These switches can be deployed wherever you need high density of Gigabit Ethernet ports or redundancy. Typically, EX4300 switches are used in large branch offices, campus wiring closets, and data centers.
  • Page 13 Juniper Networks EX Series Ethernet Switches run Junos OS, which provides Layer 2 and Layer 3 switching, routing, and security services. The same Junos OS code base that runs on EX Series switches also runs on all Juniper Networks M Series, MX Series, and T Series routers, and SRX Series Services Gateways.
  • Page 14 offices, campus wiring closets, and data centers. In data centers, these switches can be positioned as the top devices in a rack to provide connectivity for all devices in the rack and provide options for optimized airflow (hot aisle/cold aisle). To provide carrier-class reliability, EX4300 switches include: •...

  • Page 157 To determine the power budget and power margin needed for fiber-optic connections, you need to understand how signal loss, attenuation, and dispersion affect transmission. EX Series switches use various types of network cables, including multimode and single-mode fiber-optic cable. Signal Loss in Multimode and Single-Mode Fiber-Optic Cable Multimode fiber is large enough in diameter to allow rays of light to reflect internally (bounce off the walls of the fiber).

  • Page 158: Calculate The Fiber-Optic Cable Power Budget For Ex Series Devices

    For single-mode transmission, modal dispersion is not a factor. However, at higher bit rates and over longer distances, chromatic dispersion limits the maximum link length. An efficient optical data link must have enough light to exceed the minimum power that the receiver requires to operate within its specifications.
