CMX-4021S - UTP / SM, -15.0 - -18.0 dBm Tx PWR, -34.0 dBm Rx Sensitivity, 26.0 dB Budget, SC, 1310 ηm, 30 Km
The CMX-4011/4012 (one Fiber optic port) and CMX-4021/4022 (two fiber optic ports) series of Managed Multi-media Switches was especially developed as work-group switches for small and medium sized businesses with the added capability of linking remote users over Fiber Optic links. They are ideal for home-office networks and when combined with MDU (Multiple Dwelling Unit) equipment, provide economical home access to centrally or metro-supplied Ethernet services. Thus, fiber cabling can be directly supplied to the user’s home (FTTH), providing him ample speed and bandwidth for a personal local area network.
Integrated MDI/MDI-X auto-crossover and 10/100 auto-negotiation capabilities make CMX-40XX deployments simple.
The CMX-40XX series is SNMP and Web Management ready, enabling managers to remotely monitor networked connections quickly and easily via the RJ-45 and Fiber (in-band) or serial RS- 232 (out-of-band) ports. Standard single-mode and Extended-Reach single-mode connectors are available that can extend enterprise LAN management and configuration to a range of 60 km. Single- Fiber Bi-Directional fiber optic connectors can be installed as special order. CMX-40XX switches are designed to be “plug-and-go” if management is unneeded.
With full SNMP and Web Management, Loopback Test capability, and Link Fault Signaling (LFS), the CMX-40XX series are highly efficient additions to networks that require managed services across the network.
The two Fiber port models (CMX-402X), in conjunction with LFS and the IEEE 802.1D Spanning Tree protocol, enable parallel Fiber link redundancy. When a disruption in the primary link takes place, the CMX-402X will redirect data along the redundant Fiber link until the primary link is restored, ensuring 'always on' connectivity.
Integrated MDI/MDI-X auto-crossover and 10/100 auto-negotiation capabilities make CMX-40XX deployments simple.
