Filter-based Wavelength Division Multiplexer

FTTX Filter WDM module is based on Thin Film Filter (TFF) technology. The Filter-Based WDM is extensively used in EDFA, Raman amplifiers, WDM networks and fiber optics instrumentation. The FWDM series is based on environmentally stable Thin Film Filters technology. The device combines or separates light at different wavelengths in a wide wavelength range. They offer very low insertion loss, low polarization dependence, high isolation and excellent environmental stability. In 10gmodule, Filter-Based WDM product family covers following wavelength windows commonly used in optical fiber systems: 1310/1550nm (for WDM or DWDM optical communications), 1480/1550nm (for high-power DWDM optical amplifier and EDFA), 1510/1550nm (for DWDM multi-channel optical networks) and 980/1550nm (for high performance DWDM optical amplifier and EDFA) and 1310/1490/1550nm (for PON, FTTX and test instrument).
1310/1490/1550 FTTX FWDM is based on filter based platform for optical device. This multiplexer features ultra low loss, high isolation, and high reliability.
10gmodule 1490/1310/1550nm FTTH FWDM can realize the multiplexing and de-multiplexing of two communication signal 1490/1310 and 1550nm. It can expand the capacity of a single fiber to achieve bidirectional communication, so that widely used in optical network upgrade and expansion, or introduce new comprehensive business etc.
As you might know, GEPON system itself works on 1310/1490, so CATV signal here is delivered over same fiber using 1550nm, and FWDM is a place where all this get’s “mixed”.

PTN or IP RAN GPON/EPON combo backhaul would be the tendency

Nowadays, while using the swift progress connected with cell phone verbal exchanges technological know-how, this commercial-scale deployment in addition to extension connected with 3G circle structure in addition to 4G LTE technological know-how getting close, employees include began to comprehensively showcase IP-based cell phone backhaul circle. At this time, cell phone backhaul technological know-how has PTN in addition to IP JOGGED. Domestic，backhaul circle structure connected with China and taiwan Cell phone is usually PTN-based, though China and taiwan Telecom in addition to China and taiwan Unicom dependant on IP JOGGED largely.

Even so, besides PTN in addition to IP JOGGED, at this time there happens an up to date style, Broadcom considers, modest basic section backhaul by means of PON technological know-how together with EPON or GPON is usually envisioned as a completely new tendency.
This attractiveness connected with brilliant terminals along with the swift progress on the cell phone World-wide-web has taken mind-blowing increase connected with cell phone facts targeted visitors. The results ensures that by 2010 to help 2015, world wide cell phone facts targeted visitors boosts by 0. 24EB/monthto 6. 3EB/month, an expansion connected with 26 situations. This swift escalating with facts targeted visitors circle helps make employees experience completely new troubles.
