EFGH 16-GPON Port C++ Module: Single Fiber Bidirectional Optical Module, Class C++ Tx: 1490 nm, Rx: 1310 nm SFP Tx: 2.488 Gbit/s, Rx: 1.244 Gbit/s C++ Module : 4.50 dBm C++ Module : 8.00 dBm C++ Module : -30 dBm @10E-10 -32 dBm @10E-10 ZTE ETGH Service Board Product Overview ZTE ETGH Service Board is designed to increase the number of subscriber units ONT / ONUs connected to ZTE optical line terminals OLTs like C300 and C320 platforms. ZTE ETGH Service Board contains 16 optical ports for connecting subscriber devices via the EPON interface GEPON. In each port, we can install an optical transceiver transceiver SFP GEPON OLT PX20 (28dB) or SFP GEPON OLT PX20 + 33dB, transmitting/receiving data with the asymmetric speed of up to 1.25 Gbit / s over a distance of 20 km. The modules use lasers with wavelengths of 1490 nm transmission and 1310 nm reception. The division ratio of each port is 1:64. PON MAC Module
