Compatible 1000BASE SFP Transceivers

1000BASE is a term describing various technologies for transmitting Ethernet frames at a rate of a 1,000,000,000 bits per second, as defined by the IEEE 802.3-2008 standard. 1000BASE SFP transceiver is a hot-swappable input/output device that plugs into a Gigabit Ethernet port/slot, linking the port with the fiber optic network. It can be intermixed in combinations of IEEE 802.3z- compliant 1000BASE-SX, 1000BASE-LX/LH (GLC-LH-SM or GLC-LH-SMD), or 1000BASE-ZX interfaces on a port-by-port basis. Here are the most common types of 1000BASE SFP transceiver modules.

1000BASE-LX SFP Transceiver

LX stands for long wavelength. 1000BASE-LX is a physical layer specification for Gigabit Ethernet over fiber optic cabling as defined in 802.3z. 1000BASE-LX SFP transceiver uses long wavelength laser (1310 nm) over multi-mode and single-mode fiber. It is compatible with the IEEE 802.3z 1000BASE-LX standard and also supports dual data-rate of 1.25 Gbps/1.0625 Gbps with a transmission distance of 10/15/20 km. The 1000BASE-LX SFP transceiver works together with duplex LC/PC connector. The transceiver consists of three sections: a Fabry-Perot laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit. It is commonly applied for Gigabit Ethernet links, Fibre Channel Switch Infrastructure and other optical transmission systems.

1000BASE-LH SFP Transceiver

Long Haul (LH) denotes longer distances while Long Wavelength (LX) denotes less energy which is obviously shorter distance. Before it was standardized 1000BASE-LX10 was essentially already in widespread use by many vendors as a proprietary extension called either 1000BASE-LX/LH or 1000BASE-LH. 1000BASE-LH SFP transceivers are high performance, cost effective modules supporting dual data-rate of 1.25Gbps and 70km transmission distance with single-mode fiber. This transceiver consists of three sections: a DFB laser transmitter, a APD photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit. All modules satisfy class I laser safety requirements. The transceivers are compatible with SFP Multi-Source Agreement (MSA) and SFF-8472.

1000BASE-SX SFP Transceiver

SX stands for short wavelength. 1000BASE-SX is a physical layer specification for Gigabit Ethernet over fiber optic cabling as defined in 802.3z. SFP-1G85-5M-xx 1000BASE-SX SFP transceiver is a cost effective transceiver module with a wavelength of 850 nm which supports dual data-rate of 1.25 Gbps/1.0625 Gbps. It is compatible with the IEEE 802.3z 1000BASE-SX standard and operates multi-mode fibers link up to 550 m. This transceiver module consists of three sections: a VCSEL laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit. It is often applied for Fibre Channel links, Gigabit Ethernet links, Fast Ethernet links, etc. The following picture shows Fiberstore's new Cisco SFP-GE-S compatible 1000BASE-SX SFP transceiver.

1000BASE-ZX SFP Transceiver

1000BASE-ZX is a non-standard but multi-vendor term to refer to Gigabit Ethernet transmission. Fiberstore's 1000BASE-ZX SFP transceivers (like GLC-ZX-SM and GLC-ZX-SMD SFP transceivers) are high performance, cost effective modules which support dual data-rate of 1.25Gbps and 70km transmission distance with single mode fiber. They operate with a wavelength of 1550 nm to achieve distances of at least 70 km. Fiberstore's 1000Base-ZX SFP transceivers have three types of part numbers: SFP-1G85-5M, SFP-1G31-10 and SFP-1G55-70.

Fiberstore manufactures and supplies a complete range of 1000BASE SFP transceiver modules including 1000Base CWDM and 1000Base DWDM SFP transceivers. Both single-mode and multi-mode SFP transceivers are available for your choice. Besides, all these transceivers are 100% compatible with major brands like Cisco, HP, Juniper, Finisar, etc.
