How many SL phones can go on a fiber optic How many SL phones can go on a fiber optic sebastienf (TechnicalUser) (OP) 12 Nov 07 12:32 Hi,how many single line phones can go on a fiber optic?S. Fray RE: How many SL phones can go on a fiber optic Lundah (TechnicalUser) 12 Nov 07 15:41 Depends on the equipment on the ends of the fiber. RE: How many SL phones can go on a fiber optic Trotski (TechnicalUser) 13 Nov 07 06:25 the VF band used by an SL phone is digitised at 64kbit and usually 30 x 64K chan to a 2Mbit stream, do the Math from here. RE: How many SL phones can go on a fiber optic Fiberaccess (Vendor) 25 Feb 08 01:48 Not really. Most of the products I had seen so far offers just 30 FXS/FXO lines over the fiberLike this one for example: http://www.ad-net.com.tw/index.php?id=220and this because they use PDH level to transmit the signals. I ever tried find a mux with more, there was no such.Can make in different way, just take 4E1 fiber modem, and the connect with PCM E1 to 120 FXS mux, then you will have 120 POTS over fiber... RE: How many SL phones can go on a fiber optic Trotski (TechnicalUser) 25 Feb 08 03:49 It does depend on the Equipment used, DWDM SDH equip has at least 2.1Gbit per wavelength and some OLS go to 160 Wavelengths (Tbits of Data), most Muxes at a Analog phone level use PCM(30 x 64Kbit)for a 2Mbit output( VC1/2(STM1) on SDH)Or you can go Ethernet and use Voip tie lines and Gbit Network switchs at either end it reall does depend on what you really need it to do.
