What is the difference between single fiber modules and dual fiber modules?epon onu huawei compatible wholesaler

Generally speaking

The difference in appearance: The single fiber optical module has a fiber interface that connects a fiber; the double fiber optical module has two fiber interfaces, connecting two fiber;

The difference between conventional wavelength: single fiber module contains 2 different wavelengths, and the double fiber module has only one wavelength;

Conventional wavelength of a single fiber:

Gigabit single fiber:

TX1310NM/RX1550NM TX1550NM/RX1310Nm

TX1310NM/RX1490NM TX1490NM/RX1310Nm

TX1490NM/RX1550NM TX1550NM/RX1490Nm

Mark Single Single Fiber:

TX1270NM/RX1330NM TX1330NM/RX1270NM

Two fiber conventional wavelength: 850nm 1310Nm 1490nm 1550nm

The difference between rate: Generally speaking, the scope of application range of single fiber modules in 100M, Gigabit, and 10Mbarians; rarely in 40G and 100G high -speed transmission. The dual fiber module is a transmission solution that everyone is often selected.
