1GE+3FE+1POTs+CATV+WIFI4 ONU/ONT LM241TW4
Product Characteristics
LM241TW4, dual-mode ONU/ONT, is one of the XPON optical network units, support GPON and EPON two modes of self-adaptation. Applied to FTTH/FTTO, The LM241TW4 can integrate wireless functions conforming to 802.11 a/b/g/n technical standards. It also supports 2.4GHz wireless signal. It can provide users with more efficient data transmission security protection. And provide cost-effective TV service through 1 CATV port.
The 4-port XPON ONT allows users to access the high-speed Internet connection XPON port, which is shared with the Gigabit Ethernet port. Upstream 1.25Gbps, downstream 2.5/1.25Gbps, transmission distance up to 20Km. With speeds of up to 300Mbps, LM240TUW5 uses an external omnidirectional antenna to maximize the wireless range and sensitivity, so that you can receive wireless signals anywhere in your home or office and you can also connect to the TV, which can enrich your life.
FAQ
The biggest difference is that XGSPON OLT support GPON/XGPON/XGSPON, Faster Speed.
A: It depends on ports quantity and optical splitter ratio. For EPON OLT, 1 PON port can connect to 64 pcs ONTs maximum. For GPON OLT, 1 PON port can connect to 128 pcs ONTs maximum.
A: All the pon port's max transmission distance is 20KM.
A: There are no difference in essence, both are users’ devices. You could also say that ONT is part of the ONU.
