Talk About Some Details of Cisco 1000base SFP Transceiver

Cisco, as we know, one of the top 500 companies in the world, mainly supplies network and communications products and service. Its SFP transceiver is widely used with their routers and switches. Cisco SFP is an upgraded version fiber optic transceiver from the traditional one, which is smaller and more flexibility. Cisco SFPs include a wide range of the transceivers due to different working wavelengths and distances. Now I will introduce you something about the Cisco 1000Base SFP transceivers, such as GLC-SX-MM, GLC-LH-SM and GLC-ZX-SM.

Cisco SFP GLC-SX-MM

Cisco GLC-SX-MM is compliant to 1000Base SX standard for Gigabit Ethernet, used for short wavelength applications. GLC-SX-MM works with 850nm multimode fiber, its max working distance is about 1640 feet and typical data rate is 1Gbps. It uses LC duplex fiber optic connector interface.

The GLC-SX-MM transceiver consists of three sections: a VCSEL laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit. All modules satisfy class I laser safety requirements. The GLC SX MM transceivers are compatible with SFP Multi-Source Agreement (MSA) and SFF-8472. By the way, I want to say something about Cisco GLC-SX-MMD, The transceiver has the same content with GLC-SX-MM

1000BASE-SX SFP Transceiver

Cisco SFP GLC-LH-SM

Cisco GLC-LH-SM SFP is compliant to 1000Base-LX/LH standard for Gigabit Ethernet, used for long wavelength and long haul applications. GLC-LH-SM is working at 1300nm wavelength, its max working distance can reach 10km and data transfer rate at 1Gbps. GLC-LH-SM could used with both multimode optical fiber and single mode optical fiber, it is small size transceiver with LC interface, easy to use, no need further configuration.

The GLC-LH-SM transceiver consists of three sections: a FP laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit. All modules satisfy class I laser safety requirements. It fully complies with the Multi-sourcing agreement (MSA) which enables it to work in all MSA compliant platforms. The GLC-LH-SM must be operated within the specified temperature(-40°C to +85°C) and voltage limits.

Cisco SFP GLC-ZX-SM

Cisco GLC-ZX-SM SFP transceiver is compliant to 1000Base-ZX standard for Gigabit Ethernet. It works with 1550nm single mode fiber for extended working distance from 70km to 100km, with duplex LC interface and data transfer rate at 1Gbps. The GLC-ZX-SM is carrier-class quality and can be fully trusted for your most demanding LAN/WAN applications, voice projects, or network deployments.

The GLC-ZX-SM transceiver consists of three sections: a DFB laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit. All modules satisfy class I laser safety requirements. The GLC-ZX-SM transceivers are compatible with SFP Multi-Source Agreement (MSA) and SFF-8472. It fully complies with the multi-sourcing agreement (MSA) which enables it to work in all MSA compliant platforms.

Well, Cisco GLC-SX-MM, GLC-LH-SM and GLC-ZX-SM these Cisco SFP transceiver have in common is that their applications all include Gigabit Ethernet, Gigabit Ethernet, Fiber Channel, Fiber Channel,Switched backplane applications, Router/Server interface,and other optical transmission systems.
