It depends on the separation of 1310 channel from the other colours, we use 1+8 Mux's (1310 with the 'standard' 1470-1610 8 ports), and standard LX is fine in the 1310 ports.
However if you have colours close to 1310 (1330 or 1350 for example), then a normal LX will stamp all over the surrounding colours. The same applies if you try and use a 1550 ZX or ER optic in a 1550 CWDM port. I hope that helps... Regards...
