Transceiver Juniper SRX-XFP-10GE-SR-ET

optical transceivers Juniper designed to convert an electrical signal into an optical signal for data transmission over a fiber optic line and receive it with conversion back to an electrical signal at the other end. Each optical module is equipped with a receiver and a transmitter (laser). Currently, there are many varieties of optical modules Juniper, depending on form factor, operating range, data transfer rate and network environment. transceivers Juniper produced under the line of switches (for example. EX Series), routers (for example. MX Series) and other devices.

SFP module (Small Form-factor Pluggable) can transfer data at a speed of 1Gb over various distances, and due to the small size, you can increase the density of ports up to 52 pieces in one unit. SFP+ modules are identical in size to SFP modules, and can transmit data at speeds 10Gb.

For the transmission of optical signals, as a rule, multimode is used. (MultiMode) fiber and single mode (Singlemode) fiber. Dual fiber optical transceivers use an optical emitter to transmit data. (Tx, Transmitter) and photodetector (Rx, Receiver). Such modules use two fibers and one operating wavelength to transmit in two different directions.. Single-cycle transceivers operate in a pair, the transfer in two different directions by one fiber is performed on two working wavelengths. The transmit and receive signals are separated within the module using the built-in WDM-multiplexer.

Various types of connectors can be used to connect to an optical line.. For example LC type (used in two-fiber and single-fiber modules), or SC type (in single fiber modules).

module XFP slightly larger than SFP, and can transmit data over long distances. QSFP and CFP modules can operate at speeds of 40Gb and 100Gb, and accordingly they are larger, t.to. operate at higher frequencies and should have good heat dissipation.

Module using spectral division multiplexing (WDM technology - Wavelength Division Multiplexing) allow you to transmit data over a single fiber using different wavelengths, while saving fiber. With technology CWDM (Coarse Wavelength Division Multiplexing) up to 8 duplex channels can be achieved on a single fiber (the signal is divided in 20nm steps from 1270nm to 1610nm) over long distances up to 160 km.DWDM technology (Dense Wavelength Division Multiplexing) can provide 60 full duplex channels.

Most optical modules support the function DDM (Digital Diagnostics Monitoring). This digital control function of optical transceiver performance parameters allows you to monitor voltage, module temperature, signal levels and other parameters in real time..
