Recently, Toshiba officially released its first Android tablet Folio 100. According to reports, this product will be landing in Europe, the Middle East and Africa in the fourth quarter of this year.
At present, this product has now appeared on Toshiba’s stand for IFA. According to news from overseas media, the overseas media is 399 euros, equivalent to about 3,480 yuan. At present Toshiba has not yet put its plans for the US market, while the listing schedule in other regions is not yet known.
The specifications of the Folio 100 are generally consistent with previous exposures, including the use of the Nvidia Tegra 2 processor, a 1024-by-600-pixel 10.1-inch multi-touch screen, running the Android 2.2 operating system, built-in 16GB flash memory, and support for SD/MMC card expansion. Has 802.11b/g/n WiFi, Bluetooth 2.1 + EDR, support DLNA protocol; with 1.3 million pixel camera, with HDMI, USB2.0 interface; nominal life time is 7 hours, start time is about 30 seconds; body size 281 × 181 × 14mm, weight 760g. Toshiba officials revealed that will be followed in some countries to launch specific models supporting 3G networks.
Unlike many current Android devices, the Folio 100 does not have Goole's Android Market built-in, but has a special application store built by Toshiba, and it also has a dedicated website to build an application development community. The product itself is preconfigured with Opera mobile web browser, Toshiba Media Player media player, FBReader e-book reader, Document To Go office document processing tool, Evernote notes software, and Fring instant messaging tool for video chat, and can support Adobe Flash 10.1 can also use 7Digital's digital music service.
The Toshiba Folio 100 Basic Edition is priced at 399 Euros and is similar to the lowest-priced iPad, and all use 10-inch screens. However, will the Folio 100 be as good as the iPad? We may wish to continue to pay attention.
SFP transceivers are regulated by a multilateral agreement (MSA) between competing manufacturers. SFP is designed according to GBIC interface, allowing a greater port density (the number of transceivers per inch on the side of the motherboard) than GBIC, so SFP is also called "mini-GBIC". The related small package transceiver (SFF transceiver) is smaller in size than SFP, but SFF is soldered to the motherboard as a pin through-hole device instead of being inserted into the side card slot on.
SFP transceivers have a variety of different transmission and reception types. Users can select the appropriate transceiver for each link to provide the "optical performance" that can be achieved based on the available fiber types (such as multimode fiber or single mode fiber). Available optical SFP modules are generally divided into the following categories: 850nm wavelength/550m distance MMF (SX), 1310nm wavelength/10km distance SMF (LX), 1550nm wavelength/40km distance XD, 80km distance ZX, EX or EZX with a distance of 120 kilometers, and DWDM. The SFP transceiver also provides a copper cable interface, so that host devices designed mainly for optical fiber communication can also communicate through UTP network cables. There are also wavelength division multiplexing (CWDM) and single-fiber "bidirectional" (1310/1490nm wavelength upstream/downstream) SFP.
Commercial SFP transceivers can provide rates up to 4.25 G bps. Several packaging forms of 10 Gbps transceivers are XFP, and a new variant "SFP+" which is basically the same as the SFP package.
