The 1000BASE-BX-D 120km TX1550nm/RX1490nm Simplex LC/UPC BiDi SFP Optical Transceiver Module is a high-performance, ultra-long-reach SFP transceiver designed for Gigabit Ethernet single-fiber bidirectional transmission. It transmits data at 1550 nm and receives at 1490 nm, enabling full-duplex communication over a single strand of singlemode fiber (SMF) for distances up to 120 kilometers.

The 1000BASE-BX-D 40km TX1550nm/RX1310nm Simplex LC/UPC BiDi SFP Optical Transceiver Module is a high-performance, hot-pluggable SFP transceiver designed for Gigabit Ethernet single-fiber bidirectional communication. Operating at 1550 nm for transmission (TX) and 1310 nm for reception (RX), this module enables full-duplex data transmission over a single strand of singlemode fiber (SMF) for distances up to 40 kilometers.

The 1000BASE-BX-D 80km TX1550nm/RX1490nm Simplex LC/UPC BiDi SFP Optical Transceiver Module is a high-performance, hot-pluggable SFP transceiver designed for long-distance Gigabit Ethernet single-fiber bidirectional communication. It transmits data at 1550 nm and receives at 1490 nm, enabling full-duplex transmission over a single strand of singlemode fiber (SMF) for distances up to 80 kilometers.
