Product Features: GLC-BX40-U-I for Single-Fiber Applications

The GLC-BX40-U-I, along with the GLC-BX40-D-I and GLC-BX40-DA-I, is engineered for efficient single-fiber bidirectional communication. By using a single strand of SMF, these transceivers significantly reduce fiber costs while supporting a transmission range of up to 40 km.

Communication is achieved through wavelength separation:

• GLC-BX40-D-I / GLC-BX40-DA-I: 1550 nm (TX) / 1310 nm (RX)
• GLC-BX40-U-I: 1310 nm (TX) / 1550 nm (RX)

All these modules support Digital Optical Monitoring (DOM), adhering to the SFF-8472 multisource agreement (MSA). DOM functionality provides real-time diagnostics for optimal performance monitoring, including:

• Optical output power
• Optical input power
• Module temperature
• Laser bias current
• Transceiver supply voltage
