Dear all : I 've are problem about testing cisco GBIC ZX in GSR. I just 've 50 M single mode fiber. Would you mind give me some information for test the GBIC. Story : Our client 've order 3 GBIC for Three-port Gigabit Ethernet Card . But, some problem in 2 GBIC can't pass connection test. Test 1 ) I use the SC fiber cross at both GI port at e.g ( Gi2/0 to Gi 3/0). The both 3GE-GBIC-SC status can not active & the all LED is off. I 've try to sweep the TX & RX position and sweep to next Gigabit Ethernet module..etc. Still no response . Test 2 ) Next test, it test is use the one fiber cable only (single side). Make the GBIC TX & RX in loop at single fiber. Just one GBIC can enable & up. Other GBIC still is no response ! Remark : In this section the fiber have tested at both tx & rx is up. Our GBIC is 1000BASE-ZX. Following massage back from TAC: ZX can reach about 70km, it is the most powerful one GBIC. Be sure to use attenuator, otherwise GBIC may be damaged by overpower level laser!!! In order to explain different performance from your 3 GBIC, I think we can look at the tx level of max 6db to min 0db. If the one tx 0db, certainly rx will below 0db. If the other tx 6db, 50m fiber is not enough to cause 6db loss, so interface is still down and GBIC may be damaged. 9/125um SM 1000Base-ZX SC 6 tx max 0 tx min 0 rx max -23 rx min 70 km 42 mile 1000Base-ZX can reach up to 100km (60mi) by using dispersion shifted SM or low attenuation SM Regards, Eric, ____________________________________________________________________ Get free email and a permanent address at http://www.amexmail.com/?A=1 Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=19171&t=19171 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
