Choose our 4-Wire SHM-C Async to transmit data up to 4 miles (6.4 km). Run loopback tests simply by pressing a front-panel button. Open the flip-top lid for quick DTE/DCE selection.
Transformer and optical isolation protect your data from electrical interference.$174.64 -
Black Box DIN Rail RS-232/RS-485 To Fiber Driver - New - 1 x ST Ports - DuplexST Port - Multi-mode - 4 km - DC - Rail-mountable - TAA Compliant
Extend RS232, RS422 or RS485 protocols over multimode fiber so different types of equipment can talk to one another in point to point or multipoint environments. Serial extenders work well in factory automation, building automation, and process automation where PLC's with RS232, RS422 or RS485 interfaces are used to control devices. The ability to extend the distance to their devices over fiber while also adding protection from electrical interference which can be caused by large motors which are prevalent in these environments is very beneficial.

Black Box Industrial DIN Rail RS-232/RS-422/RS-485 Fiber Driver, Single-Mode - New - 1 x SC Ports - DuplexSC Port - Single-mode - 14.40 km - Rail-mountable - TAA Compliant
The MED102A is our premium serial to single-mode fiber optic converter. It provides versatile connections between asychronous full- or half-duplex serial equipment using duplex single-mode fiber optic cable. The converter can also be set up in a multi-drop configuration to allow one serial device to communicate with multiple devices on a fiber ring. It supports mixed standards, which allows you to replace other converters and isolators and add the EMI/RFI protection inherent to fiber optic communications.

Black Box T1/E1 to Fiber Mux, Single-Mode Duplex SC, 30 km, with LAN Connector - Optical Fiber, Twisted Pair - Fast Ethernet - 100 Mbit/s - 1 x RJ-45 - TAA Compliant
- It also has an integrated 10BASE-T/100BASE-TX copper LAN port for Ethernet connections.
- Ideal for extending T1 and Ethernet communications over fiber to a remote PBX and other equipment.
- Local loopback on both the copper and fiber ports.
- It also offers remote fiber loopback and circuit test modes.
- Configurable alarm relay contacts enable you to set up audio/visual fault notification.
Get extra distance for your T1/E1 and 10-/100-Mbps Ethernet communications with a pair of T1/E1 to Fiber Muxes. Unlike ordinary fiber-based T1 extenders, the four-port muxes eliminate the requirement that each channel have its own fiber link.
Learn More
In a typical enterprise application, these unmanaged muxes use optical media to aggregate and extend four T1 or E1 channels from a local PBX to four T1/E1 connections at a remote PBX.
Use them also for mobile backhaul applications where you want a cost-effective, multiservice platform that's capable of delivering Ethernet and TDM services over a fiber link. Extend four T1 lines from your TDM network and an Ethernet connection from the IP network to a cell site, for instance.
With fiber optics, your T1/E1 and Ethernet communications also receive the benefits of security, immunity against EMI and RFI, and protection against the harmful effects of ground loops.
The T1/E1 to Fiber Muxes offer simple installation and use. DIP switches are used to configure the units for T1/E1 line operation and enabling port alarm relays. For troubleshooting, the T1/E1 to Fiber Mux offers local loopback on both the copper and fiber ports, as well as remote fiber loopback and circuit test pattern modes - minimizing the need for testing functions at both ends of the link.$2,087.20 -
