Different package of the optical transceiver module

In reality, the classification according to package of the optical module is the most common method.

1 X9 package

1 X9 package optical modules, sometimes also called the 9-pin or 9PIN optical module, the name suggests, this fiber optic module nine PIN angle is the most common of the early optical module package, the type of very large market demand ,mainly used in fiber optic transceiver, PDH Optical, optical switches, single Multi-mode converter as well as some industrial control applications.

GBIC package

GBIC transceiver, the abbreviation of the Giga Bitrate Interface Converter upcoming gigabit electrical signal is converted to optical signals module. GBIC designed for hot-plug. GBIC is interchangeable products meet international standards. This Gbic optical module used widely before SFP package. That is gradually being replaced after the SFP optical module lauched. They have basically been eliminated on the currently market in addition to some older models of equipment still using.

SFP package

SFP transceiver, Small Form-factor Pluggables, small hot-pluggable optical module is an upgraded version of the early GBIC module, the volume smaller, higher integration than the GBIC fiber module, which is currently on the market's most popular optical module,

XFP package

XFP transceiver, 10 Gigabit Small Form Factor Pluggable, is a hot-swappable, independent of the communication protocol optical transceivers, the XFP is usually used to 10G bps SONET / SDH, Fibre Channel, Gigabit Ethernet and other applications, but also of CWDM DWDM link.

Relative to the 1X9 and SFP modules, XFP has a higher transmission rate and transmission capacity, so the price is much higher than ordinary fiber module.

SFP + package

SFP + optical modules, SFP PLUS optical module, SFP optical module upgrade, with a higher transmission rate, usually up to 8.5G or 10G, the size of the XFP module, this module than earlier smaller at the same time have the same rate, so for communications equipment manufacturers in the same space to deploy a more intensive light module offers the possibility, so more and more applications.

XPAK package
The XPAK optical module definition same with Xenpak, because it is a 4-channel (10 Gbps attachment-unit interface) connection at the physical layer /
Media access controller interface to partition the modular I / O channels. Use Xpak the Xenpak output pin, but there is one exception, that is, it including Xenpak standard version in the future not on the clock signal. Compared with Xenpak module size Xpak share space on the I / O cards .Between than the Xenpak small. In fact Xpak Xenpak module directly improved version of the volume reduced by half of the optical interface, electrical interface with the original Consistent.

XENPAK package

XENPAK transceiver 10 Gigabit Ethernet optical transceivers (independent of the transceiver circuits and optical components of optical signals for small devices, with Standard Specification for switches and routers, the interface part). Agere, Agilen,, Mitsubishi, Pine Photonics, Tyco and Defined Optillion companies xENPAK Working Group, provides for the product dimensions, light plug type and electrical pin-out configuration and power Energy and other parameters

X2 package

X2 transceiver is based on the XENPAK Multi-Source Agreement optical module that occur before, but more than XENPAK optical modules more of the smaller size and volume of the module and Parameters similar to XENPAK, about the size of the XENPAK the half the size of.
SFF is divided into 2X5 pin or needle 2X10 can be soldered directly on the device.

SFP module or transceiver tips

Outline

SFP package - hot-plug small package module, the highest rate of up to 10G, the use of the LC interface. SFP is an abbreviation of the SMALL FORM PLUGGABLE, can be simply understood as the upgrade version of GBIC. SFP module volume ratio is reduced by half than GBIC module.Other features of the SFP modules are same with GBIC. So sfp transceiver also be called  MINI-GBIC.

SFP transceiver ’s Category

By  the rate : 155M/622M/1.25G/2.125G/4.25G/8G/10G,most used in the market are :155M and 1.25G .The 10g sfp module ‘s demand is rising now.

By the wavelength:850nm/1310nm/1550nm/1490nm/1530nm/1610nm

The difference between single-and multimode

Multimode: almost all of the multimode fiber dimensions are50/125μm or 62.5/125μm, and bandwidth (fiber information transmission amount) is usually 200MHz to 2GHz. Multimode Opticalmulti-mode fiber transmission of up to 5 km. Light emitting diode orlaser light source. The ring-pull, or in vitro color is black.

Single-mode: the size of the single-mode fiber for 9-10/125μmunlimited amount of bandwidth and low loss characteristics, andcompared to the multi-mode fiber. Single-mode optical transceiver used for long distance transmission, and can sometimes reach 150-200 km. LD or narrow spectral line of the LED as a light source. Thering-pull, or in vitro color is blue, yellow or purple.

The difference and connection: single-mode fiber is cheap, but thesingle-mode device was expensive compared to similar multi-modedevices. Single-mode devices can usually run on a single-mode fiber, can also be run on a multi-mode fiber, multimode devices is limited to running on a multimode fiber.

10G module experience from the development of 300Pin, XENPAK, X2, XFP, and ultimately can transmit 10G signal with the same size of SFP  , which is called SFP +. SFP With miniaturization cost advantages to meet the demand for high-density equipment, optical module and pushed from the 2002 standard, 2010 has been 10G market mainstream replacing the XFP .

The advantages of SFP + optical module :
1, the SFP + has a more compact form factor than X2 and XFPpackages (SFP size);
2, the same type of XFP, X2, XENPAK direct connection;
3  low cost than the XFP, X2, XENPAK products.

The difference between the SFP + and SFP:
1, SFP and SFP + and the appearance of the same size;
2, SFP protocol specification: IEEE802.3, SFF-8472;

The difference between the SFP + and XFP:
1, the SFP + and XFP are 10G optical modules, and other types of 10G modules can communicate with each other;
2, the SFP + and XFP Dimensions;
3, because the smaller the SFP + signal modulation function, serial/ deserializer, the MAC, clock and data recovery (CDR) and electronic dispersion compensation (EDC) function from the module to the motherboard on the card;
4, the XFP compliance agreement: XFP MSA;
5, the SFP + compliance with the Protocol: IEEE 802.3ae, the SFF-8431 SFF-8432;
6, the SFP + is a more mainstream design.
3, SFP + protocol specification: IEEE 802.3ae, the SFF-8431, SFF-8432.
