Cisco Linksys MGBBX1D Compatible 1000BASE-BX-D SFP operates using 1490 nm TX and 1310 nm RX over a single-mode fiber and transmits 1.25 Gbps up to 20 km using a simplex LC/UPC. The device supports DOM/DDM for temperature, voltage, bias and Tx/Rx power. The electrical interface is SFP MSA low voltage differential with 100 Ω nominal impedance, and typical power consumption is ≤1 W. The commercial operating range is 0 to 70°C, laser classification is Class 1, and it is RoHS compliant.
This device can be used in place of several other compatible models, including Cisco Linksys MGBBX1D, Juniper Networks SFP-GE20KT14R13, Brocade E1MG-BXD-20, HPE J9142B-20, H3C SFP-GE-LX20-SM1490, HW BiDi SFP-GE-20-SM1490, Dell SFP-GE-BX20D-1490, Extreme Networks MGBIC-BX20-D, and Alcatel-Lucent SFP-GIG-BX-D20.
