The GLC-BX80-D-I is a Gigabit SFP transceiver for 1000BASE-BX single-fiber bidirectional links up to 80 km, featuring digital optical monitoring (DOM).
1000BASE-BX80-D is a standard for single-fiber bidirectional Gigabit Ethernet transmission over single-mode fiber at 80 km reach.
Single-fiber bidirectional uses two wavelengths on one fiber—one for transmit and one for receive—to carry traffic in both directions.
DOM provides real-time laser bias current, optical output/input power, temperature, and voltage monitoring for proactive link management.
It supports reliable single-mode fiber transmission up to 80 km under standard optical loss budgets.
Use ITU-G.652 single-mode fiber with maximum attenuation of 0.4 dB/km for optimal performance.
It transmits at 1310 nm and receives at 1490 nm for bidirectional operation on a single fiber.
It supports a fixed data rate of 1.25 Gbps, compliant with Gigabit Ethernet standards.
It is compatible with any Gigabit Ethernet or SFP-capable switch, router, or optical transport platform supporting 1000BASE-BX.
Yes, the GLC-BX80-D-I is hot-swappable, allowing insertion or removal without powering down the host device.
Operating temperature ranges from 0 °C to 70 °C, and power consumption is typically below 1 W.
Slide the SFP module into the host’s SFP port until it clicks, then connect the single-mode fiber pigtail to the TX and RX ports.
Yes, it interoperates with any standard-compliant 1000BASE-BX device from other vendors.
The module provides an optical loss budget of up to 18 dB to accommodate fiber attenuation and connector losses.
Yes, it is RoHS-compliant and meets relevant industry standards for lead-free and halogen-free designs.
