FRM220-FXO-FXS-SFP - POTS (RJ11) over fiber telephone line extender w/SFP slot

Product description
The FRM220-FXO-FXS-SFP is a POTS (RJ11) port over fiber optic media converter (POTS extender). The PSTN two-wire POTS telephone port can be configured either as an FXO (PBX trunk) or FXS (telephone set/fax machine/dial-up modem) device just by a simple DIP switch setting. Using a pair of converters, a telephone line can be extended over a fiber optic circuit, providing full service and features like Caller ID. The converter can be used in service mode, alowing connection of 2 telephone sets in between. The FRM220-FXO-FXS-SFP is a modular POTS over fiber media converter. Any 155Mbps rate optical SFP transceiver can be installed into the single SFP slot of the FRM220-FXO-FXS-SFP converter, offering maximum flexibility for the optical interface.

When the FRM220-FXO-FXS-SFP POTS over fiber converter is placed in the FRM220 rack with in-band and SNMP management, the converters status, type, version, fiber link status, POTS RJ11 port status and alarms can all be displayed. Configuration is also available to enable or disable the port, reset the port, do far end fault setting, and initiate local or far end loop-back tests.

The FRM220-FXO-FXS-SFP POTS over fiber extender is extremely versatile, being available in several versions of power supply: external AC adapter, embedded internal AC power, embedded internal DC neg. 48V power or dual combo embedded AC and DC power supply. Same model can also be installed in the FRM220 chassis, in matter of minutes. In an always changing and growing networking environment, such a versatile model allows network operators to switch to higher density and aggregation hubs without the need to purchase new fiber optic converters. The FRM220-FXO-FXS-SFP media converter is one of the best choices of media converters for data carriers and service providers.
