Q: What is the OSFP (Octal Small Form Factor Pluggable)? A: The OSFP is a new pluggable form factor with eight high speed electrical lanes that will initially support 400 Gbps (8x50G). It is slightly wider and deeper than the QSFP but it still supports 32 OSFP ports per 1U front panel, enabling 12.8 Tbps […]
The long-awaited public launch of efforts to develop the Octal Small Form Factor Pluggable (OSFP) optical transceiver module for 400-Gbps applications has finally arrived. The multisource agreement (MSA) development group, led by Arista Networks, includes 49 members. «It is rare to see so much industry support behind a new optics module form factor,» said Andreas […]
What standard addresses 100G, and when will this standard be complete? The IEEE 802.3ba technical requirements were ratified in the recent April 2010 sponsor ballot. The document has been forwarded for approval to RevCom and is expected to be released in June 2010. When is customer implementation of 100G expected? Early end-user adoption is expected […]
The cable jacket comprised with different materials based on different applications, In the United States, plastics used in the construction of plenum cable are regulated under the National Fire Protection Association standard NFPA 90A: Standard for the Installation of Air Conditioning and Ventilating Systems. All materials intended for use on wire and cables to be […]
OTDR Price is getting economical recently, how to get a good test trace from an cost effective OTDR is critical, the following lists is an instruction about how to get good test result. 1. Select the right pulse width, by selecting a longer or shorter Pulse Width, you can control the amount of backscatter level […]
WDM – Wavelength Division Multiplex WDM wird auch als Wellenlängenmultiplex oder Wellenlängenvielfach bezeichnet. Jede Farbe des Lichtes wird einer bestimmten Frequenz der elektromagnetische Welle zugeordnet. Durch die Verwendung unterschiedlicher Farben (Frequenzen) lassen sich auf einem Lichtwellenleiter mehrere Datenkanäle unabhängig voneinander betreiben. Diese Methode entspricht dem Prinzip des Frequenzmultiplexverfahrens. Wobei die Wellenlänge mit der Frequenz vergleichbar […]
Ein passives optisches Netz ist ein Glasfasernetz, welches zur Signalverteilung ohne aktive Komponenten auskommt. Es arbeitet mit optischen Splittern, die über keine elektrischen Vermittlungsfunktionen verfügen. Passive optische Netze sind im Bereich zwischen Vermittlungsstelle und Teilnehmeranschluss für Gigabit-Glasfaseranschlüsse installiert. Sie funktionieren als Zugangsnetze für die Teilnehmer zum weltweiten Daten- und Kommunikationsnetz. Man unterscheidet zwischen passiven optischen […]
