Comparison between single-mode and Multi-mode fiber

November 3, 2011

Comparison with single-mode fiber Multi-mode fiber has higher "light-gathering" capacity than single-mode optical fiber. In practical terms, the larger core size simplifies connections and also allows the use of lower-cost electronics such as light-emitting diodes (LEDs) and vertical-cavity surface-emitting lasers (VCSELs) which operate at the 850 nm and 1300 nm wavelength (single-mode fibers used in telecommunications operate at 1310 or 1550 nm and require more expensive laser sources. Single mode fibers exist for nearly all visible wavelengths of light).

Quad Small Form-factor Pluggable

November 2, 2011

QSFP cables provide a high density, high bandwidth, cost effective solution for a variety of markets and applications including switches, routers, HBA’s, high performance computing and mass storage sub-systems by mfr’s such as IBM, Cisco, qLogic, etc. QSFP cables are designed for data rates up to 40Gb/s supporting Fibre Channel, Ethernet, SDH/SONET and Infiniband standards.

SFP+ Transceiver for Enterprise and Metro Networks

November 2, 2011

Milpitas, Calif., August 16, 2011 – JDSU (NASDAQ: JDSU and TSX: JDU) today announced that it has developed the first tunable SFP+ transceiver to replace fixed wavelength SFP+ transceivers and legacy products in Enterprise and Metro networks.

Tunable SFP+ Transceiver Benefits

November 2, 2011

Flexible network management. A tunable SFP+ transceiver will be remotely configured for a specific wavelength to support bandwidth changes as needed in Enterprise or Metro networks.
 

The Enhanced Small form-factor Pluggable

November 2, 2011

The enhanced small form-factor pluggable (SFP+) is an enhanced version of the SFP. It supports data rates up to 10 Gbit/s. The SFP+ was first published on May 9, 2006, and version 4.1 published on July 6, 2009.SFP+ supports 8 Gbit/s Fibre Channel, 10 Gigabit Ethernet and Optical Transport Network standard OTU2.

Optical Interconnect

November 2, 2011

Optical interconnect is a way of communication by optical cables. Compared to traditional cables, optical wires are capable of a much higher bandwidth, from 10 Gb/s up to 100 Gb/s.
