SFP+ ***0 nm LC Connectors *0km on SMF, with DOM function.



SFP transceivers are available in a variety of different transmit and receive types, and users can select the appropriate transceiver for each connection to provide the "optical performance" achievable based on the type of fiber available (such as multimode fiber or single-mode fiber). SFP optical modules can generally be divided into the following categories [2]:

SX: **0 nm wavelength, transmission distance **0 meters, using multi-mode fiber (MMF, multi-mode fiber)

LX: ***0 nm wavelength, transmission distance *0 km, using single-mode fiber (SMF, single-mode fiber)

EX: ***0 nm wavelength, transmission distance *0 km, using single-mode fiber (SMF, single-mode fiber)

ZX: ***0 nm wavelength, transmission distance *0 nm, using single-mode fiber (SMF, single-mode fiber)

TX: Electrical port module, using RJ**5 copper cable interface

CWDM: sparse wavelength division multiplexing SFP optical module

DWDM: dense wavelength division multiplexing SFP optical module



Commercial SFP transceivers are capable of delivering rates up to 4.*5 Gbps. Several packages for *0 Gbps transceivers are XFP, and a new variant "SFP+" that is basically the same package as SFP.  



According to the speed, it can be divided into the following types:

**5 Mbps, which is STM*1 in SDH system, optical modules with this rate are also commonly used in **0 M Ethernet devices;

1.*5 Gbps, optical modules with this rate are also commonly used in Gigabit Ethernet devices, and are often called Gigabit SFP optical modules;

*0 Gbps, optical modules with this rate are commonly used in *0 Gigabit Ethernet devices. With the development of optical communication, more and more optical modules with this rate have been widely used;

*0 Gbps, the optical module of this rate (QSFP module), there are 4 groups of *0G lights inside to synthesize *0G rate through CWDM.



PON optical modules are specially used in PON devices, and generally have different transmission and reception rates, and are asymmetrical optical modules.  



The stick ONU optical module [3] is a new type of SFP transceiver. This module integrates the functions of the SFP transceiver and the ONU, and can be inserted into the switch to enable the switch to access the PON optical network.
