Der Industriestandard Cisco Kleiner Formfaktor steckbar (SFP) Der Gigabit-Schnittstellenkonverter verbindet Ihre Switches und Router mit dem Netzwerk. Das Hot-Swap-fähige Ein-/Ausgabegerät wird an einen Gigabit-Ethernet-Port oder -Steckplatz angeschlossen. Optische und Kupfermodelle können auf einer Vielzahl von Cisco-Produkten verwendet und in Kombinationen von 1000BASE-T kombiniert werden, 1000BASIS-SX, 1000BASE-LX/LH, 1000BASIS-EX, 1000BASE-ZX, oder 1000BASE-BX10-D/U auf Port-für-Port-Basis.
1000BASE-T SFP für Kupfernetzwerke Das 1000BASE-T SFP arbeitet mit der Standardkategorie 5 ungeschirmte Twisted-Pair-Kupferverkabelung mit Verbindungslängen bis zu 100 M (328 ft). Unterstützung für Cisco 1000BASE-T SFP-Module 10/100/1000 Autonegotiation und Auto MDI/MDIX.
GLC-LH-SMD Overview
Cisco GLC-LH-SMD 1000BASE-LX/LH SFP is made for Both Multimode and Single-Mode Fibers.
The 1000BASE-LX/LH SFP, compatible with the IEEE 802.3z 1000BASE-LX standard, operates on standard single-mode fiber-optic link spans of up to 10 km and up to 550 m on any multimode fibers. When used over legacy multimode fiber type, the transmitter should be coupled through a mode conditioning patch cable. 1300-nm wavelength, extended operating temperature range and DOM support, dual LC/PC connector.
This Figure shows the appearance of GLC-LH-SMD.
The table provides cabling specifications for the SFPs that you install in the Gigabit Ethernet port.
Note that all SFP ports have LC-type connectors, and the minimum cable distance for all SFPs listed (multimode and single-mode fiber) Ist 6.5 feet (2 M).
