Cisco MGBBX1D Compatible 1000BASE-BX20-D BiDi SFP Module 20km(SMF, 1490nm-TX/1310nm-RX, Simplex LC, DOM)
Product Overview
The HYTOPTODEVICE Cisco MGBBX1D compatible BiDi SFP transceiver is a professional single-fiber bidirectional gigabit optical module, specially designed for overseas enterprise network renovation, MSP project deployment, and large-scale European and American IT procurement. Featuring accurate Tx1490nm/Rx1310nm wavelength configuration and 20km single-mode fiber transmission capacity, this simplex LC SFP module serves as the perfect downlink pairing solution for 1000BASE-BX-U uplink modules, helping global buyers save half of fiber cabling costs in network construction.
Different from generic ordinary optical modules, this MGBBX1D equivalent transceiver supports flexible OEM white-label customization, private logo printing, and customized packaging services, fully meeting the personalized branding needs of overseas distributors and system integrators. All products pass strict real-Cisco-device testing and 72-hour high-temperature aging screening, ensuring zero-error plug-and-play operation on mainstream Cisco IOS systems without firmware conflicts or alarm logs. Compliant with SFF-8472 and IEEE 802.3z international standards, it retains complete DDM real-time monitoring functions to support long-term stable operation of commercial network projects.
