The FRM301 is a 3U high 19" Rack, 16-slot modular media converter rack. It provides an economic solution in high density fiber converter installations in enterprises or central offices. All critical components, Power, fans, management module and interface cards are hot swappable, allowing online field replacement.

The FRM301-1000ES and FIB1-1000ES are Gigabit Ethernet 10/100/1000Base-T to 1000Base-SX/LX SFP. They are managed (when installed in FRM301 with management) or non-managed stand-alone media converters, which give you the options to choose from a wide range of industry standard SFP modules with LC connectors.

The FRM301-1000TS and 1000TG are transparent Gigabit Ethernet 1000Base-T to 1000Base-SX/LX SFP or GBIC. They are managed (when installed in FRM301 with management) or non-managed stand-alone media converters, which give you the options to choose from a wide range of industry standard SFP modules with LC connectors.

The FRM301-1000MG and FIB1-1000MG are transparent multi-mode fiber to GBIC fiber converters at speeds up to 1.25Gbps. They are managed (when installed in FRM301 with management) or non-managed stand-alone media converters, which give you the options to choose from a wide range of industry standard GBIC modules with SC connectors.

The FRM301-1000DS is a fiber to fiber optical media converter and repeater that allows data rates up to 2.5Gbps. FRM301-1000DS supports 2R regeneration, which consists of re-amplification and reshaping. This converter is compatible with fiber interfaces such as 100Mbps Fast Ethernet, 155Mbps STM1, 4, 16, Fiber Channel 1, 2, and OC3, 12, 24, 48.

The FRM301-10/100F, FIB1-10/100F, FIB2-10/100F are Fast Ethernet 10/100Base-TX to 100Base-FX manageable (when installed in FRM301 with management) or stand-alone media converters, which give you the options to choose from the most popular fiber cabling connectors,ST, SC, or FC. Both multi-mode and single mode converter models are available as well as BiDi which allows bi-directional transmissions using only a single fiber cable.

The FRM301-E1/T1 is a fiber media transport for G.703 E1/T1 transmissions. The BNC model provides unbalanced 75 Ohm coaxial E1 connections while two RJ-45 models provide either balanced 120 Ohm E1 or 100 Ohm T1 connections over twisted pair wiring.

The FRM301-DATA and DATA/H are media converters for Nx64K up to 2.048Mbps or high-speed (up to 8.192Mbps for "H" model) synchronous or low speed synchronous and asynchronous data transmissions (V.35, RS-232, RS-530, X.21 or RS-449) over fiber optical media.

The FRM301-Serial provides a fiber converter solution to extend asynchronous RS-485 or RS-232 transmission distance up to 2km over multimode fiber or up to 120km over single mode fiber. The converter is equipped with multiple interface circuits for connection to RS-232 or RS-485/422 (2 or 4 wire, full or half duplex). The FRM301-Serial secures data transmission over EMI resistant fiber at speeds up to 256kbps for RS-232 or up to 1024kbps for RS-485/422.
