Module Knowledge

Half-Duplex is like the dreaded "one lane" road you may have run into at construction sites. Only one direction will be allowed through at a time. Railroads have to deal with this scenario more often since it's cheaper to lay a single track.

A 40 Gb/s optical link was demonstrated using a four-channel bidirectional OSA module. The OSA module was designed with individual SiOBs for VCSEL, PD and M-PD array chips…

In an electronic communications system, return loss is the portion of a signal that is reflected back to the transmitter.

Receiver Sensitivity is the minimum acceptable value of received power needed to achieve an acceptable BER or performance.

The maximum receivable power is called the Overload Optical Power, also called the Saturation Power, which means max optical power detected by the receiving end of the optical module.

The 10-Gigabit XENPAK transceiver is a static-sensitive device. Always use an ESD wrist strap or similar individual grounding device when handling the XENPAK transceivers or coming into contact with the modules.

The X2 transceiver module is a static-sensitive device. Always use an ESD wrist strap or similar individual grounding device when handling X2 transceiver modules or coming into contact with modules.

Before removing a GBIC Transceiver, please notice that because invisible laser radiation may be emitted from the aperture of the port when no cable is connected, avoid exposure to laser radiation and do not stare into open apertures.

The XFP transceiver module is a static-sensitive device. Always use an ESD wrist strap or similar individual grounding device when handling XFP transceiver modules or coming into contact with modules.

These installation notes provide instructions for installing 1000BASE-T Gigabit Interface Converters (GBICs) in Catalyst 2900 XL and so on...

How to Install a 10G XFP Transceiver Module? Please visit this page. You will need these tools to before installing the 10G XFP transceiver modules.

Optical fiber is the transport medium that has emerged to accommodate the expected long-term growth in the communications industry. Taking advantage of the wide bandwidth — the principal advantage in optical communications systems — requires stringent con

OC-3/STM-1 is a network line with transmission speeds of up to 155.52 Mbit/s using fiber optics. Depending on the system OC-3 is also known as STS-3 (electrical level) and SDH SFP. These modules are also used for Fast Ethernet application.

There are multiple kinds of transceiver module available for use with different types of wire, fiber, different wavelengths within a fiber, as well as for communication over different distances.

Actually, all lasers are susceptible to back reflections. Back reflections disturb the standing-wave oscillation in the laser cavity, and the net effect is an increase in the effective noise floor of the laser.

Before removing the dust plugs and making any optical connections, follow these guideline.

The 10-Gigabit Ethernet X2 transceiver module is a hot-swappable I/O device that plugs into 10-Gigabit Ethernet ports.

CFP (C Form-factor Pluggable) Optical modules deliver 100-gbps data rates to meet the demand of increasing traffic. Long-haul network equipment is being redesigned to support CFP modules…

The CFP multisource agreement (MSA) was formally launched at OFC/NFOEC 2009 in March by founding members Finisar, Opnext, and Sumitomo/ExceLight…

Technically, the CFP will work with multimode fiber for short-reach applications, but it is not really optimized in size for the multimode fiber market, most notably because the multimode fiber market requires high faceplate density...
