Sumitomo introduces the batch productino fine low speed SFP light transceiver

A few days ago, Sumitomo Electrics Industry Ltd. claimed to develop the batch productino fine low speed SFP light transceiver " series 6G " ,And sold formally since July.

SFP( 1)Light transceiver ( Hereafter referred to as SFP) Accord with MSA ' 2)Small-scale light transceiver of the agreement. The light transceiver before this needs welding on the communicating device inner base plate, but SFP does not need specialty welded, can be plugged on the communicating device, this specialty obtains high evaluation of numerous communicating device manufacturers, is becoming the most light transceiver of demand now.

The intersection of Sumitomo and for meet, increase to the demand of SFP, set up Sumitomo Electric Industries (Suzhou) by city in Suzhou of China on last April Company Optoelectronic apparatus Co., Ltd. ( Hereafter referred to as SPEC Company) ,Start to make from optical device to the light transceiver composingly and produce integratively since April of this year. Series 6G are for realizing the products produced in SPEC Company integratively and developed newly, begin smooth LAN and public largest low speed of demand for telecommunication at first ' The transmission speed is 3 kinds of 100Mb/s, 156Mb/s, 1.25Gb/s) Production of the light transceiver.

The specialty of series 6G is shown as follows:

(1)Have integrated the technology fostered and optimum design that realizes in production in the quantity of SFP Integrate in the quantity before this technology fostered in production, make great efforts to realize used IC, optical device and improvement and optimization that packed. The result compares with original products, has realized photoelectric characteristic, acclimation characteristic and batch productino finer design.

(2)But flexible to deal with user require specification CPU built-in to take Through built-in CPU, can control various alarm signals, specifications more accurately. It should be to the communication agreement of different control signals in each system of users' that it can be flexible that its result is.

(3)Through producing integratively, has shortened lead time Use the small-scale mere apparatus (TOSA from signal transmission 3)), the signal accepts that uses the small-scale mere apparatus (ROSA 4))Production last equipment,until in inner to produce integratively in factory, shorten lead time to original 1/3. In the future, Sumitomo Company will advance the development of series 6G of corresponding to 2.5Gb/s too, it is estimated that begins 2.5Gb/s to correspond to the batch productino of edition in SPEC Company within 2008.

(*1) SFP: Small Form Factor Pluggable

(*2) MSA: Multi Source Agreement, among a plurality of supplier / user through the intersection of packing of product and size, the intersection of base pin and the intersection of person who dispose and main specification detail of Tonghua altogether, establish the method that the products supply the system steadily.

(*3) TOSA: Transmitter Optical Sub Assembly

(*4) ROSA: Receiver Optical Sub Assembly

Luxtera introduces the light transceiver that can integrate the computer mother board

The news on November 13, Luxtera11 released on day one can mount onto the single chip light transceiver on the computer mother board directly, it and declare by scheme and can last every one passway 10Gpbs the costs of devices every /under Gits.

Luxtera shows this transceiver is the OptoPHY series products of its company, it integrates electronic element and optical component on a CMOS form chip. And show it will be meaning photon technology takes an important great step again in evolution that this new light transceiver produces collinear appearance, it sets aside the module solution of traditional hot-plug to change into the chip scheme in year of the board, it accords with the photoelectric system level chip integration technology of the demand in the future to make and produce.

The senior vice-president BradSmith of LightCounting represents, 10Gbit/s is a mainstream of the systematic interconnection field, and Off-The-Shelf high speed communication system at present, such as the switchboard / router, the supercomputer, telecommunication equipment, data communication and server adopt 2.5G/5GSNAP12 technology that developed in 1998. Usually made up of the transceivers of 4 2.5Ws, probably 400 dollars of value for each one among them, the power consumption 10W of 1600 dollars, and die in very large fabric board space altogehter. The market needs to look for the new solution at this moment, for example occupied from before the space connected the scheme to convert to the present mere integrated chip scheme greatly.

It is reported OptoPHY series products that Luxtera put out have only 1 passway and 4 passway product at present, it is estimated that will put out 12 passways of products next year, Luxtera respect shows the scheme that this serial transceivers of theirs will be adopted can make every Gbit/s power consumption reduce to 20nW.

Luxtera Company represents, the mere integrated chip technological scheme of the OptoPHY series transceiver products, it is the ideal solutions of corporate network, Ethernet, still support the application function of the bottom panel at the same time, can well overcome the difficult problem of VCSEL100 rice range of the traditional multimode optical fiber scheme.
