Hi,
For wideband WDM system, we have:
wideband WDM based on fused type 1×2 splitter joint with isolator;
equipement allows two-directional optical transmission on one fiber in 1310 or 1550 band, with standard OLT in PDH and SDH systems (STM4 inclusive);
main parameters:
◦ bandwidth 1310±20nm or 1550±20nm;
◦ insertion loss (for one pair) < 8dB;
◦ channel isolation > 32dB;
◦ operating teperature range –5…+70°C.
