Fiber optic transceiver SC interface gigabit single-mode

Gigabit single-mode SFP transceivers with SC interfaces provide reliable long-distance fiber connectivity, supporting 1. 25 Gbps data rates and distances from 2 km up to 180 km depending on the model.

Overview

A Gigabit single-mode SFP (Small Form-Factor Pluggable) transceiver is a hot-swappable module that connects network devices like switches, routers, and media converters to single-mode fiber networks.

The S

C interface is a standard connector type that ensures secure and low-loss optical connections. These transceivers are widely compatible with major networking brands such as Cisco, Nortel, D-Link, and Netgear.

Key Specifications

Data Rate: Typically 1. 25 Gbps, suitable for Gigabit Ethernet, 1G Fiber Channel, and SDH applications. Fiber Type: Single-mode fiber (SMF), optimized for long-distance transmission.

Connector Type: SC (single or duplex), with some models supporting LC connectors as well. Transmission Distance: Ranges from 2 km to 180 km depending on the module type and wavelength. Standard modules often support 10–40 km, while high-performance or BiDi modules can reach up to 120–180 km.

Wavelength: Commonly 1310 nm or 1550 nm for long-distance single-mode links.

Bi

Di modules use paired wavelengths (e.g., 1310/1550 nm) for single-strand operation.

Hot-

Pluggable: Allows easy installation and replacement without powering down the device. Compatibility: Works with 1000BASE-LX/LH, 1000BASE-EX, and 1000BASE-ZX standards for single-mode fiber.

Bi

Di (Single-Strand) SFP ModulesBiDi SFPs use Wavelength Division Multiplexing (WDM) to transmit and receive data over a single fiber strand, reducing cabling requirements. These modules require a complementary pair (A and B types) to function properly and are available for distances such as 20 km with SC connectors. ApplicationsLong-distance Gigabit Ethernet links between buildings or data centers.

Fiber channel and SDH networks requiring single-mode connectivity. Network upgrades or expansions where SC connectors are standard. Environments needing hot-swappable, plug-and-play optical modules for minimal downtime.

Considerations

Ensure the transceiver type matches the fiber standard (single-mode vs multimode) and the wavelength is compatible with the link distance.

For Bi

Di modules, always pair the correct complementary module to avoid link failure. Inline optical attenuators may be required for very short single-mode links to prevent receiver overload. These transceivers provide a flexible, reliable solution for high-speed, long-distance fiber optic networking with SC interfaces, making them ideal for professional and enterprise environments.
