       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
