1.25G SFP Transceiver Alternative Solution

Introduction

SFP (Small Form Pluggable) optical module is a compact transceiver used for both telecommunications and data communication applications. It can interface a network device motherboard (for a switch, router, media converter or similar device) to a Fiber Channel or Gigabit Ethernet (GbE) optical fiber cable at the other end. Due to its small size, it has replaced the formerly ubiquitous Gigabit Interface Converter (GBIC) gradually. And now it becomes the most used fiber optic transceiver module in the fiber communication industry.

SFP Module Series

SFP transceivers are available in a wide range of data rates and fiber coverages, which allows users to choose the most suitable transceiver for each link. Most used SFP transceivers are the 1.25 Gbps transceiver modules which are of different transmitter and receiver types such as 1000BASE-T, 1000BASE-SX, 1000BASE-LX/LH, etc. Here depict such kinds of transceivers.

1000BASE-SX SFP Transceiver

1000BASE-SX SFP transceiver is a cost effective 850nm module supporting dual data-rate of 1.25Gbps/1.0625Gbps. It is compatible with the IEEE 802.3z 1000BASE-SX standard and operates multimode fibers link up to 550 m. The fiber optic transceiver consists of three sections: a VCSEL laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit. It is usually applied for Fiber Channel links, Gigabit Ethernet links, Fast Ethernet links, etc.

1000BASE-LX/LH SFP Transceiver

1000BASE-LX/LH SFP transceiver is a high performance 1310nm transceiver for single-mode fibers. 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. It has three part numbers: SFP-1G31-10-xx, SFP-1G31-15-xx and SFP-1G31-20-xx. The transceiver consists of three sections: a FP laser transmitter, a PIN photodiode integrated with a trans-impedance preamplifier (TIA) and MCU control unit. It is commonly applied for Gigabit Ethernet links, Fiber Channel Switch Infrastructure and other optical transmission systems.

10/100/1000BASE-T SFP Transceiver

10/100/1000BASE-T SFP Transceiver is compatible with the Gigabit Ethernet standard as specified in IEEE STD 802.3. It supports data rates of 10/100/1000 Mbps, fully satisfying 10/100/10001000BASE-T applications such as LAN 10/100/1000Base-T Fiber Channel links, Gigabit Ethernet over Cat 5 Cable, Switch to Switch Interface, Router/Server interface, etc.
