AOC (ACTIVE OPTICAL CABLE)

AOC is a cabling technology that accepts the same electrical inputs as a direct attach cable, but uses optical fiber "between the connectors". AOC uses electrical-to-optical conversion on the cable ends to improve speed and distance performance of the cable without sacrificing compatibility with standard electrical interfaces. As a leading AOC factory, T&S active optical cable assembly is designed in to meet needs for high-density cabling interconnect systems like data centers, and high-performance computing application.

T&S Communication Active Optical Cables (AOCs) achieve high data rates over long reaches, using a fraction of the power of other brands while providing streamlined installation for high-performance computing and storage applications. As a professional AOC factory in China, T&S offers a wide range of active optical cables, such as 100G QSFP28 AOC,10G SFP+ AOC, 25G SPF28 AOC(or 25G AOC), etc, with different specifications at good prices.

FAQs of Active Optical Cable

What is CWDM4 MSA?

CWDM4 MSA is a general specification for low-cost 100g optical interface, 2km in data center application.

CWDM4 MSA alliance was jointly launched by Avago, Finisar, JDSU and Oclaro on March 31, 2014. Four 25gbps signals are used and multiplexed to two single-mode optical fibers by CWDM. IEEE 802.3bj kr4 RS FEC technology is adopted.

CWDM MSA said the release of the standard has collected feedback from more than 40 companies, including system OEMs, optical module manufacturers, chip manufacturers, fiber optic cable manufacturers, etc. At present, members of cwdm4 MSA alliance include:

Avago Technologies

Brocade

ColorChip

Finisar

HiLight Semiconductor Ltd

Hitachi Metals

II-IV Incorporated

JDSU

Juniper Networks

Kaiam

Mitsubishi Electric

NeoPhotonics

Oclaro

What is LWDM？

The full name of lwdm is Lan WDM, which usually refers to a wavelength range dense WDM technology in 100g optical modules. According to the wavelength defined by IEEE 802.3, the wavelength of LAN WDM mainly covers 10km.

The wavelength is 1295.56nm, 1300.05nm, 1304.58nm, 1309.14nm.

What is pam4 technology?

Pam4 is a kind of PAM (pulse-amplitude modulation) modulation technology, namely fourth-order pulse amplitude modulation.

PAM signal is a popular signal transmission technology after NRZ (nonreturn to zero).

NRZ signal uses high and low signal levels to represent 1 and 0 of digital logic signal. Each clock cycle can transmit 1 bit of logic information.

Pam4 signal is transmitted by four different signal levels, and each clock cycle can transmit 2-bit logic information, namely 00, 01, 10, 11.

Therefore, under the same baud rate, the bit rate of pam4 signal is twice that of NRZ signal, the transmission efficiency is doubled, and the cost can be effectively reduced.

What kind of SFPs?

SFP, small hot pluggable module. Finger sized transceivers are suitable for many different rates and protocols, including multimode fiber, single-mode fiber, copper wire, and multi-wavelength interfaces for WDM systems. In a pluggable transponder, a pluggable network card is used to transmit a specific wavelength of WDM.
