This module uses a Simplex LC connector over 9/125µm Single Mode Fiber (SMF). Because this is a BiDi optic transmitting at 1550nm and receiving at 1310nm, you must pair it at the opposite end of the fiber strand with a 1310nm-TX / 1550nm-RX counterpart (such as the LS-BL31552G-20C) to complete the link.
