CWDM Mux/Demux The Coarse Wavelength Division Multiplexing-CWDM Mux/Demux is often a flexible plug-and-play network solution, which helps insurers and enterprise companies to affordably implement denote point or ring based WDM optical networks. CWDM Mux/demux is perfectly created for transport PDH, SDH / SONET, ETHERNET services over WWDM, CWDM and DWDM in optical metro edge and […]
Shielded cabling systems are strongly recommended for category 6A (Class EA) installations, but the user still has to choose between two optional shielding options: F/UTP or U/FTP. This presentations shows the inherent benefits of U/FTP cables of F/UTP cables. The comparison is done for cables containing only a single drain wire. Cables with an overall […]
UTP cable (Unshielded Twisted Pair) Twisted pair cable is the most used, it does not possess any additional protection to the PVC coated and it has 100 Ohm impedance. The connector most commonly used in this type of cable is the RJ45, similar to the RJ11 used in phones (but a little large), but they […]
Before you install the MPO connectors in the data cnter, it is essential that all the fiber end-faces and the ferrule are really clean. especially when you thinking about lining up 12, 16, 24 or 32 pieces of 9um fibers in one or two rows, it requires tremendous precision. Any dirts in the mix on […]
The QSFP form factor is today’s industry workhorse for delivering 40 and 100GbE. The «Q» is for “quad» — a nod to the four-channel electrical interface, with each lane running at 25 Gbps for 100GbE. QSFP-DD adapts the same basic concept as its predecessor, but doubles the electrical contact density, via eight differential pairs capable […]
What is the standard for OM5 fiber? Telecommunications Industry Association (TIA) initiated a workgroup in October 2014 to develop guidance for a wide band multimode fiber (WBMMF) 50/125 μm standard to support short wavelength division multiplexing (SWDM) transmission. The TIA-492AAAE Standard was published in June 2016.The IEC WB MMF standard is anticipated to be completed […]
SFP-DD is short for SFP Double Densty, it is a new module and cage/connector system similar to current SFP module, but with an additional row of contacts providing for a two lane electrical interface. It is being developed by the SFP-DD MSA as a key part of the industry’s effort to enable high-speed solutions. The […]
OSFP is short for Octal Small Form Factor Pluggable. it is being designed to use eight electrical lanes and each lane for 50GBE to deliver 400GbE. compared with QSFP transceiver, It is slightly wider and deeper, but it still supports 36 OSFP ports per 1U front panel, enabling 14.4 Tbps per 1U. OSFP is a […]
The C form-factor pluggable (CFP) is a multi-source agreement to produce a common form-factor for the transmission of high-speed digital signals. The c stands for the Latin letter C used to express the number 100 (centum), since the standard was primarily developed for 100 Gigabit Ethernet systems. CFP8 use of a 16x25G electrical interface […]
How many form factors for 100G Optical Transceivers? QSFP28: Taking the technology and squeezing down to the familiar QSFP form factor CFP: The first 100G transceiver form factor, CFP’s are larger modules, and were based originally on 10 lanes of 10G CFP2: The successor to the original CFP module, this boasts a higher port density […]
