The manufacturer of BlueOptics and BlueLAN network products, CBO, welcomes the e-commerce specialist DiTo-Shopping as a new partner. As of now, customers can purchase BlueOptics and BlueLAN products through the new DiTo shopping platform blueoptics-shop.de.

The CWDM transceivers are working in a specific optical frequency ranges defined by the ITU-T. In 2002 the ITU standardized a channel spacing grid for use with CWDM (ITU-T G.694.2), using the wavelengths from 1270nm through 1610nm with a channel spacing of 20nm.

In the modern and ultra-high tech Datacenters of today, more bandwidth is needed and used to support the latest demands in the Networking world especially in a server-virtualization environment where multiple virtual machines are being combined on a single physical host server. To be able to accommodate the growing number of operating systems and applications and at the same time providing scalability and reliability, virtualization requires noticeable increased data transmission rates between the servers and the switches in the Datacenter.

Today there are different optical transceivers available on the market. They come in various form factors offering speeds from 100Mbps to 100Gbps and are fully compliant to the MSA and IEEE 802.3 standards. Some of the more popular form factors include SFP, SFP+, XFP, GBIC, XENPAK, QSFP and QSFP28.

The manufacturer of BlueOptics and BlueLAN network products CBO announces the collaboration with the ITK distributor Michael Telecom. From now on BlueOptics transceiver modules for the use in systems for data transmission via fiber optics for manufacturers such as HP, D-Link, Netgear, Lancom, ZyXEL, Planet, and others are available at Michael Telecom.

The BlueLAN Direct Attach Cable series from CBO, a manufacturer of network products, now includes a new product for the flexible connection of switches among each other and across neighboring racks: Flexible Ribbon Direct Attach Cables with SFP+ or QSFP Connector. The 3M™ twinax flat ribbon cable technology allowed CBO to create a new variant of DAC Direct Attach Cables.

The use of fiber optic transceiver modules and fiber patch cable plays an important role in fiber optic data transmission, especially data transmission between the switches and equipment, and now are widely used in both telecommunication and data communications. Telecommunication testing equipment also needs fiber patch cord to connect to the systems for testing scenarios. Besides the data center connections and interconnections, fiber patch cords may be used in various access methods such as CATV connections and on the last mile in the FTTH - Fiber to the Home.

When it comes to fiber networks, choosing the right fiber optic cable type is essential. Fiber optic cables used in data and telecommunication are most commonly categorized in two groups:

The small form-factor pluggable modules are the most popular family of fiber optic transceivers. SFP+ transceivers are used in almost all fiber optic networks. The main reason for using fiber optic cable in campus networks is the distance limitation of unshielded copper cables. The advantages of SFP+ transceivers are outlined below, these advantages are the basis of the extensive popularity of the SFP+ transceivers.

During the past few years, there is a dramatic increase in the demand for bandwidth requirement for our communications. Whether be in a communication service provider or in a public or private data centers, a development in connectivity that can cater higher speed, bandwidth is needed. That is why last July 2014, an industry consortium was formed to create a new Ethernet connectivity standard in data centers. This standard was called 25 Gigabit Ethernet or 25Base-T, developed by IEEE 802-3 task force P802.3by. This standard was derived from the 100GB Ethernet Standard, however, its operation works as a single lane connection with 25Gbps that can be run on fibers or coppers. Last June 2016, this technology was commercially released using new transceiver interfaces called SFP28 (1x25Gbps) and QSFP28 (4x25Gbps). This article will discuss the transceiver form factor 25G SFP28.
