  ZyFLEX’s
new design of Fiber Optic Mutliplexer with versatile
enhancement for full user customization.
FORTA 155E is a stand-alone STM-1
Optical Multiplexer that includes 4/8/12/16 lines
of T1/E1 tributary interfaces, a V.35 (Nx64Kbps)
leased line interface, and an Ethernet over SDH
interface.
Each of FORTA 155E’s T1/E1 tributary modules
provides 4 lines of E1/T1, and the interfaces
can be set to either E1 or T1, depending on individual
requirements. A maximum of up to 16 lines of T1/E1
interfaces can be provided. FORTA 155E assists
service providers to deploy swift setup of optical
networks, and extend their CO interfaces to support
remote sites, which resolves issues such as line
shortage, and transmission distance limitations.
FORTA 155E adopts the FTTB (fiber to the building)
and FTTC (fiber-to-the-curb) optical network architecture.
Together with other telecommunication devices
that include E1/T1 interfaces, such as the E1
Multiplexer, DLC, Fractional E1/T1, and PABX,
FORTA 155E can provide connections to various
user sites, such as commercial towers, residential
buildings, remote towns, mobile phone base stations,
hospitals, and schools.
