This transceiver requires standard OS2 single-mode fiber (9/125μm SMF) terminated with a Simplex LC connector. Because this unit transmits at 1550nm and receives at 1310nm (1550nm-TX / 1310nm-RX), the remote end must be paired with an opposing 1310nm-TX / 1550nm-RX 2.5G BiDi 40km module (such as the LINK-PP LS-BL31552G-40I) to form a complete bidirectional link over a single fiber core. by LINK-PP Technical Support
