PON SONNET Gigabit Ethernet Fibre Channel
G-PON OLT & ONU Point to Multi Point Bidi Transceivers SFF & SFP
Ligent ITU-T G.984.2 Class B and Class B+ G-PON transceivers are designed for Fiber to the Home, Business or Curb (FTTX) systems employing burst mode receivers and transmitters. They support asymmetrical data links of 1244/2488 Mb/s and can serve up to 16 or 32 subscribers over distances of up to 20 km. The upstream ONU transceiver incorporates a high-performance 1310 nm F-P or DFB burst mode transmitter and 1490 nm CW mode PIN/TIA or APD/TIA receiver. The Downstream OLT transceiver incorporates a high-performance 1310 nm APD/TIA burst mode receiver and 1490 nm DFB CW mode transmitter. Commercial and industrial temperature range options are available.
