WS-G5487

Juniper was founded by Pradeep Sindhu, Dennis Ferguson, and Bjorn Liencres in February 1996 in California. Scott Kriens (formerly of Stratacom) became CEO in October 1996, and is credited with leading Juniper’s commercial success. It was reincorporated in March 1998 in Delaware. Juniper went public on June 25, 1999. (source: wikipedia.org)

The Cisco® Catalyst® 6500/Cisco 7600 Series Supervisor Engine 720 (WS-SUP720-3BXL) is a family of Supervisor Engine(s) designed to deliver scalable performance and rich set of IP features in hardware. Its hardware-based feature set enables applications such as traditional IP forwarding, Layer 2 and Layer 3 Multiprotocol Label Switching (MPLS) VPNs, Ethernet over MPLS (EoMPLS) with quality of service (QoS) and security features. The WS-SUP720-3BXL integrates a high-performance 720 Gbps crossbar switch fabric with a forwarding engine in a single module, delivering 40 Gbps of switching capacity per slot (enabling 4-port 10GE and 48-port 10/100/1000 density line cards). With hardware-enabled forwarding for IPv4, IPv6 and MPLS, the system performance is capable of 400 Mpps for IPv4, 200 Mpps for IPv6 traffic, with features and 1024 VRFs each populated with up to 700 routes/VRF for MPLS.

1000Base-ZX extended reach GBIC(singlemode)

3rd party component - 100% compatible with Cisco WS-G5487 (1000BASE-ZX)

The WS-G5487 GBIC (1000BASE-ZX) operates on ordinary single-mode fiber-optic link spans of up to 70 km in length. Link spans of up to 100 km are possible using premium single-mode fiber or dispersion-shifted single-mode fiber. (Premium single-mode fiber has a lower attenuation per unit length than ordinary single-mode fiber; dispersion-shifted single-mode fiber has both lower attenuation per unit length and less dispersion.)

The WS-G5487 GBIC (1000BASE-ZX) must be coupled to single-mode fiber-optic cable, which is the type of cable typically used in long-haul telecommunications applications. The WS-G5487 GBIC (1000BASE-ZX) will not operate correctly when coupled to multimode fiber, and the WS-G5487 (1000BASE-ZX) is not intended to be used in application environments (e.g., building backbones or horizontal cabling) where multimode fiber is frequently used.

The WS-G5487 GBIC (1000BASE-ZX) is intended to be used as a physical medium dependent (PMD) component for Gigabit Ethernet interfaces, as found on various switch and router products. Teh WS-G5487 (1000BASE-ZX) will operate at a signaling rate of 1250 MBaud, transmitting and receiving 8B/10B encoded data.
