okay,

ga lebih dari beberapa hari lagi, gue akan berangkat lagi untuk instalasi lanjutan dari migrasi network custumer di Balikpapan, Issues yang muncul sekarang adalah soal interkoneksi dari optical infrastructure, dimulai dari tra dimana switch2 yang existing menggunakan GBIC (Gigabite Interfaces Converter) dan yang switch2 yang baru menggunakan SFP (Small Form-Factor Pluggable)


1. Issues one : The Transceivers

GBIC Transceiver

SFP Transceiver

okay, first of all, i wrote this for me especially, so i can get brief and compact
understanding about my project, so if you get bored on your way, you can close this page :)



on that installed in my custumer site is 100BASE-FX, and what the hell is that?
sure, great definitions comes from the principal, so i got this link :

The 100BASE-FX SFP operates on ordinary multimode fiber optical link spans of up to 2 kilometers (km) in length. Customers implementing Cisco 100BASE-FX SFP can use 1000BASE-X SFPs in the future (including SX, LX/LH, ZX, and coarse wavelength-division multiplexing SFPs).



TECHNICAL SPECIFICATIONS

Platform Support

okay, the one that installed in custumer site is 100Base-FX and we will replace it with 1000 Base-LX, both using multimode? see the problem, yes indeed becouse multimode using 1000Base-LX is onli up to 550 m instead 2 Km like 100Base-FX that already installed in my custumer site, then i googled....and...

i found this :

http://www.cisco.com/en/US/prod/collateral/modules/ps5455/prod_bulletin0900aecd80425a37.html

"Under certain conditions, Cisco supports Gigabit Ethernet deployments with 1000BASE-LX gigabit interface converter (GBIC) and Small Form-Factor Pluggable (SFP) transceivers with mode conditioning patch (MCP) cords. Table 1 lists the part numbers applicable to the Cisco solution to support multimode fiber (MMF) links up to 2 km."

the requirement to do so is as noted on the link above :

• The customer uses the Cisco transceivers listed in Table 1.

• The Gigabit Ethernet signal is launched with a mode conditioning patch cord.

• The customer or Cisco account representatives demonstrate and document error-free full-duplex transmission for 8000 seconds on each specific link greater than 550m. (This number of seconds is chosen to yield a bit error rate (BER) of at least 1e-12 with 99-percent confidence.)

• The suggested setup is shown in Figure 1: two Gigabit Ethernet traffic generators (SmartBits or IXIA or equivalent Gigabit Ethernet traffic generators) connected to two Cisco Ethernet switches or routers at each end of the link. The Cisco platforms are in turn connected to the multimode fiber with mode conditioning patch cords. Line-rate traffic flows in both directions. The Cisco IOS^® Software show interface command can be used to detect any input errors on both interfaces. The goal is to demonstrate error-free transmission for 8000 seconds.

• The Cisco TAC reserves the right to ask for recertification of the link performance every 3 years.

so yes, it can be done....hehehehe
