Fiber optic transceivers are key components of fiber optic transmission network. They are designed in small form-factor with some integrated optical sub-assemblies which can be suitable for high-density network. The major cost components of a transceiver module are the transmitter optical sub-assembly (TOSA), which converts an electrical and the receiver optical sub-assembly (ROSA). However, inside a BiDi (Bi-Directional) transceiver, there is a component with called "BOSA" (Bidirectional Optical Sub-Assemblies) which acts the role of TOSA and ROSA but with different principle.

AT-SPSX Overview
The Allied Telesis AT-SPSX SFP is a hot pluggable 1000BASE-SX SFP Transceiver module. It is capable of reaching a maximum operating distance of up to 500 m and transmits using an 850 nm wavelength. The AT-SPSX SFP uses a fiber optic cable with LC connectors. The AT-SPSX SFP transceiver is designed to be used in ATI products such as the AT-8000 and AT-9400 series switches.
AT-SPLX10 Overview
The AT-SP10LR is a hot pluggable 10Gbps small form factor transceiver Module. It is compliant with the SFF-8431 SFP+ Electrical Multi-source Agreement (MSA) with five digital monitoring functions: Temperature, Vcc, Tx optical power, Tx laser bias current and Rx received optical power. The Allied Telesyn 10GBASE-LR SFP uses a fiber optic cable with LC connectors.

AFBR-703SDZ & AFCT-701SDZ Overview
The Avago AFBR-703SDZ transceiver is part of its SFP+ SR product family. This transceiver uses Avago’s 850 nm VCSEL and PIN detector technology to provide an IEEE 10 Gbs Ethernet design compliant with the 10 GBASE-SR standard. The AFBR-703SDZ transceiver is designed to enable 10 Gbs Ethernet equipment designs with very high port density based on the new electrical and mechanical specification enhancements to the well known SFP+ specifications developed by the SFF Committee.
The Avago AFCT-701SDZ transceiver is part of its SFP+ LR product family. This transceiver uses Avago’s 1310 nm DFB and PIN detector technology to provide an IEEE 10 Gbs Ethernet design compliant with the 10 GBASE-LR standard. The AFCT-701SDZ transceiver is designed with an...

SFP+ transceiver is widely deployed in applications and becomes much more pervasive due to its smaller form factor, less power consumption and its increased port density compared with XFP transceiver. Each SFP+ transceiver houses an optical receiver and transmitter. One end of the transceiver is an optical connection complying with the 10GbE and 8GFC standards, while the other end is an SERDES framer interface (SFI) serial interconnect handling differential signals up to 10 Gbit/s. In order to keep a SFP+ transceiver achieving high performance, the engineers need to acquaint with the key challenges related to testing SFP+ transceiver. This article will first walk through the SFP+ testing challenges and then focus on one kind of testing measurement.

As technology continues to improve, the size of transceiver modules has become smaller and smaller. In addition to the size, the rate of optical transceiver also becomes faster and faster, such as 1.25 G, 2.5 G, 4 G, 10G, 40G and 100G, etc. However, when came up to 10G, people found that the encapsulation is too small to keep many components. In order to solve this problem, XFP modules were launched as a new transceiver standard. Here is what you need to know about XFP optical transceivers technology.
Introduction of XFP Transceiver
In fact, XFP is not the first 10G transceiver in the market. The 10G transceiver market has gone through 300Pin and XENPAK/XPAK/X2 before XFP came out. As these types of products are intergrated with SerDes chips, we usually call them transponders instead of...

As one of the most important components of PON (Passive Optical Network) systems, the market of PLC (Planar Lightwave Circuit) splitters has grown rapidly. If you are the first time to buy PLC splitters, you might be curious about the package type of it. Actually, it is not as complex as you think.
Different Package Type PLC Splitters
At present, there are six major package type of PLC splitters according to different applications, suce as, bare fiber splitter, module splitter, rack-mount splitter, fan-out & blockless splitter, Tray splitter and LGX splitter. Of course, these are the basic types and there are upgrade version on their foundation offered by different vendors. For example, the following shows us the PLC splitters of Fiberstore with different package types.
