Small package for optical transceiver or into a new generation of trend

Communication network transmission capacity and expanding rate along with the increase of modern information network of optical fiber communication becomes the main transmission means, now in the optical communication network, such as a wide area network ( WAN ), metropolitan area networks ( MAN ), local area network ( LAN ) needed as one of core of optoelectronic devices and optical transceiver optical transceiver module more and more types, are increasingly high requirements, complexity is developing at an amazing speed. Optical transceiver, the optical transceiver module sharp increases in the diversity, needs to continue to develop related technology that satisfies the application requirements. The optical transceiver development direction may be moving towards miniaturization. The optical transceiver optical transceiver module for optical fiber access network core devices promote the trunk optical transmission system to low cost development, makes the optical network configuration is more complete and reasonable. In order to adapt to the requirements of communication equipment for optical device, optical module is highly integrated small package development. Highly integrated photovoltaic module the user without having to deal with high speed analog signal, shorten the R & D and production cycle, reduce the vitality of types of procurement, reduce production costs, therefore also more and more receives equipment manufacturer's favor. The optical transceiver transceiver module of photoelectric device encapsulated by the larger size of the dual-in-line forms for the development of coaxial package forms; optical interface structure from ST, FC to SC and the smaller LC, MT-RJ type connection form, a corresponding optical transceiver optical transceiver module packaging form from the metal packaging development into the plastic package, consisting of a single interface separation module developed to interface transceiver module. Pin arrangement and encapsulated by a dual-in-line 20 foot, 16 foot separation module to the development of the single row 9 feet ( 1X9 ), two 9 foot ( 2X9 ) and the future of double rows of 10 foot and 20 double foot transceiver module. SFF ( Small Form. Factor ) small packaged optical module adopts the advanced precision optics and integrated circuit technology, dimensions of only ordinary duplex SC ( 1X9 ) type optical fiber transceiver module half, in the same space can be doubled optical port number, can increase the line port density, reduce the system cost per port. Because the SFF small package module adopts a similar MT-RJ interface with the copper network, size and common computer network wire interface, is conducive to the existing copper network device to transition to a higher rate of optical fiber network to meet the rapid growth of network bandwidth requirements. Small package for optical transceiver optical transceiver module to the appearance of small package size advantage, so that the network device interface of the optical fiber number doubled, single port rate Gigabit magnitude, to meet the INTERNET era of network bandwidth demand rapid growth. Can say small package for optical transceiver optical transceiver module technology represents a new generation optical communication device development trend, is the next generation high speed network foundation.
