Cisco GLC-2BX-D Compatible 2-Channel 1000BASE-BX CSFP Transceiver Module (SMF, 1490nm-TX/1310nm-RX, 10km, LC Duplex, DOM) provides an efficient option for those looking to implement two independent Gigabit Ethernet channels in a single compact SFP module. Each channel supports 1.25 Gbps over 9/125 µm single-mode fiber (SMF) using a 1490 nm DFB laser for transmission and a 1310 nm PIN photodetector for reception, producing bi-directional transfer for distances up to 10 km, ensuring reliable and stable bi-directional transmission.
This module is hot pluggable, CSFP MSA compliant, and has Digital Diagnostic Monitoring (DOM) capabilities to analyze real-time power, voltage, and temperature. The TX/RX utilizes a power supply of 3.3 V, comes with a low EMI metal housing, supports applications utilizing an LC/UPC duplex interface, and provides a high level of electrical integrity. The module meets full compatibility with Cisco GLC-2BX-D specifications while allowing for identical operation with compatible sourced products from other major vendors. Delivery is suitable within a network topology working with Fast Ethernet, Telecom, and Data Center applications.
