PON-WDM and OADM
GPON and XGS-PON use different wavelengths. XGS-PON uses a longer wavelength (1577 nm) in the downstream direction compared to GPON (1490 nm). In the upstream direction, XGS-PON, on the other hand, uses a shorter wavelength (1270 nm) compared to GPON (1310 nm). It means that the traditional PON-WDMs used in GPON networks (1310/1490 + 1550 nm) do not work in XGS-PON networks . XGS-PON networks require a wider wavelength range for use. If you want RF video (1550 nm) on the same fiber in XGS-PON networks, OADM (Optical Add/Drop multiplexer) is used instead of traditional PON-WDM.
We keep also PON-WDMs in stock, which are needed to build GPON-networks. Those can be installed into NAF1000 casings, 19” panels and into other casings as well.
The 1550 OADM (Optical Add/Drop Multiplexer), on the other hand, is suitable for GPON, XGS-PON and NG-PON2 networks to separate the wavelength of cable TV from other data traffic. The OADM has a narrow 1550nm (±7.5nm) window, which allows to add or remove the wavelength in question.
