1.25G SFP Module Connector Options

Simplex SC SFP

The Simplex SC SFP module uses a single fiber for bidirectional communication when used as a BIDI/BiDi optical configuration. This type of transceiver is useful where fiber availability is limited and a single fiber is preferred for transmission and reception.

Simplex LC SFP

The Simplex LC SFP module is another single-fiber optical transceiver option. BIDI versions commonly use different transmit and receive wavelengths and are normally deployed as a matched optical pair.

Duplex LC SFP

The Duplex LC SFP module uses two fibers, with one fiber dedicated to transmission and the other to reception. Duplex LC is widely used for conventional two-fiber optical links.

Transmission Distance Options

Universal Fiber Solutions provides multiple distance options to support different network requirements.

10km SFP Module: Suitable for short-to-medium distance single-mode fiber links.

20km SFP Module: Designed for longer single-mode fiber connections where a 10km optical module is not sufficient.

40km SFP Module: Suitable for extended fiber links used in telecom, ISP and enterprise networking.

60km SFP Module: Designed for longer-distance single-mode optical connectivity.

80km SFP Module: Suitable for long-distance fiber infrastructure and extended network links.

100km SFP Module: Designed for high-distance single-mode fiber connectivity where extended optical reach is required.

120km SFP Module: Provides an extended-reach option for long-distance single-mode fiber network deployments.
