Many people do not know the difference between SFP and SFP+, so sometimes unnecessary trouble. 10G module has gone from 300Pin, XENPAK, X2, XFP development, and ultimately with the same size and SFP 10G transmission signal, which is the SFP+. SFP With its compact and low cost advantages to meet the equipment needs of high-density optical module, the standard introduced from 2002 to 2010 has replaced 10G XFP become the market mainstream.

Divided according to the rate of 155M / 622M / 1.25G / 2.125G / 4.25G / 8G / 10G, used more on the 155M and 1.25G market, 10G demand to increase positive attitude development.

SFP is SMALL FORM PLUGGABLE (Small Form Factor Pluggable) acronym, can be simply understood as an upgraded version of GBIC, SFP modules are small by half. But on the same panel configuration more than double the number of ports. Other features SFP and GBIC modules basically the same. Some switch vendors said the SFP module as small GBIC (MINI-GBIC).

GBIC Gigabit Interface Converter abbreviation, is the gigabit optical signal is converted to an electrical signal interface device. Design hot-swappable, GBIC is an interchangeable products that meet international standards in the market account for a large market share.

Polatis all-optical switch manufacturer, today launched the network for the protection of the optical layer failures Polatis 6000n all-optical solutions to protect business switch PSS.

FTTH (Fiber To The Home), the name suggests is an optical fiber directly to the home. Specifically, FTTH refers to the optical network unit (ONU) installed at the home user or business user, a series of optical access user of the optical access network application types except FTTD (fiber to the desk) the closest off. FTTH is a distinctive feature not only provides more bandwidth, but also enhances network data format, speed, wavelength and protocol transparency, relaxes the environmental conditions and power requirements, simplifying maintenance and installation.

APON the mid-1990s developed, and was able to develop a fiber-based standard include IP data, video and Ethernet services for business and residential users, logical ATM and PON were selected as the network protocol and network platform, because ATM is seen as the only able to provide various types of communication protocols, and is the most economical broadband PON fiber solution.

Optical connector, also known as fiber optic connector, commonly known as joint activities. It is used for the detachable (activity) connected between the optical fiber and optical fiber device. It is the two end precision optical docking, so that the light energy emitted optical output can maximize the receiving fiber coupled to go, and effects due to their involvement optical link and to minimize the impact on the system.

Optical transceiver module can be based on package, application rate, transmission distance, the use of optical fiber, the use of laser wavelength and so do a variety of categories. We choose the optical module when these factors must be marked, do not misunderstand talent. For example, in a communication system used in the single-mode fiber optic module package 40 km 1550nm 2.5Gbps SFP module, or used in a data system in the 500 meters 10Gbps XFP package 850nm wavelength multimode fiber modules.

SFF (Small Form Factor), small package optical modules. Use of advanced precision optics and integrated circuit technology, size is only half of ordinary duplex SC (1X9) fiber optic transceiver modules, in the same space can be increased to double the number of ports of light, you can increase the line port density, lower per-port system costs.
