Xenpak module is attached thru 70pin SFP connector andcircuit board, the statistics channel XAUI interface; Xenpak guide allIEEE 802.3ae-described optical interface, the line side can provide10.Three Gb / s, nine.Ninety five Gb / s or four × three.A hundred twenty five Gb / s price.
Xenpak transceiver module is packaged in a four.8 × 1.Four × 0.7 cubicinches of space, integrated 310 nm semiconductor disbursed comments (DFB) laser, direct modulation mode, built-in temperaturecontrol tool. The Xenpak G.652 single-mode fiber transmission distance can reach 10 km, appropriate for application in themetropolitan region, is the mainstream made from the modern-day 10G Ethernet port. In addition to the photoelectric a part of the multiplexing/ demultiplexing module (MUX / DEMUX) is the the Xenpak internal any other critical function the Xenpak more than 50% of electricity is the multiplexing / demultiplexing module ate up, so Xenpak lightlarger module size, strength intake is also massive.
The utility of the Xenpak transceiver is rather easy, simplest one optical module can recognise 10G Ethernet optical interfacefunctions. The difficulty of circuit design is the layout of high-speeddata interfaces, XAUI, XAUI interface, consisting of 8 pairs of fee of3.A hundred twenty five Gb / s, and serial, containing clock differential line. XAUI interface to the performance of a direct effect on the forwarding overall performance of the system.
X2-10GB-SR
Xenpak and X2 module are both from the Xenpak wellknown evolution. Its inner characteristic modules are basically same with Xenpak ,and the circuit board packages b are equal too, additionally the usage of one module to realize10G Ethernet optical interface functions. Due to the the Xenpak light module is mounted on the circuit board while the circuit board slottedto acquire more complex, can not obtain the high-density programs. About half of of the Xenpak and X2 optical modules volumeimproved after simplest Xenpak immediately into the circuit board, it's far carried out to high-density rack systems and PCI card packages.
Xenpak and X2 optical modules can offer two varieties of circuit interface: XAUI and Serial Framer Interface (SFI-four), can be used for10G Ethernet ,also can be used for OC-192 SDH and 10GFC. It may be said Xenpak and X2 have very similar general, X2 adjustments contemplated within the rail systemcompared Xenpak . The enterprise commonly consider that the 2 specs will subsequently combine. Welcome to click 10Gtekstore.
