Catalyst Systems SMTC1310/1550-1x8 SC/APC Fiber Optic Coupler 1U Rackmount

Catalyst Systems SMTC1310/1550-1x8 SC/APC Fiber Optic Coupler 1U Rackmount

This is a Catalyst Systems SMTC1310/1550-1x8 passive fiber optic coupler chassis — a 1x8 single-mode splitter/coupler module designed to split or combine optical signals at 1310nm and 1550nm wavelengths. The unit is housed in a 1U rackmount enclosure with rack ears installed, and the front panel is populated with 8 SC/APC fiber optic adapter ports.

Applications

Fiber optic couplers (also called splitters or passive optical splitters) are used in fiber-to-the-premises (FTTP/FTTH), CATV fiber distribution, test lab setups, and telecom central office environments to distribute an optical signal from a single source across multiple output fibers. A 1x8 coupler splits one input signal into eight equal output paths, making it a building block in passive optical networks (PON). The SC/APC connector type — identified by its green housing and angled ferrule — is standard in high-return-loss applications such as CATV, DWDM, and FTTH deployments, where back-reflection must be minimized. Rack-chassis coupler modules like this one allow high-density fiber distribution within a standard 19-inch equipment rack, commonly used in data centers, telecom central offices, and campus fiber infrastructure.
