Precision OT debuts ASIC technology to enable tunables and extended reach
Precision Optical Technologies has debuted its Dispersion Compensation ASIC (application-specific integrated circuit) technology to enable emerging technologies such as 25G tunable transceivers.
In DWDM networks, chromatic dispersion becomes more pronounced as transmission distances increase. Its impact on data quality is particularly noticeable once transmission speeds exceed 10G.
Although many processing tools are available for compensation, Precision OT’s claims that its pre-distortion technique offers various advantages. “By going the pre-compensation route, our technology swaps a single conventional component in an intensity-modulated direct-detect pluggable transceiver with a modified version that performs dispersion compensation,” said David Calhoun, Technical Director of the AEG at Precision OT.
He added, the “technology is non-invasive, compared to other technologies which might require changes to the fiber plant or need customized book-ended links.”
Precision OT works with customers to maximize the capabilities of existing infrastructure and leverage access network technologies such as DOCSIS 4.0 ESD, R-OLT PON uplinks and 5G fronthaul/backhaul.
While today’s 10G DWDM transceivers can facilitate transmission distances of up to 80km, the available 25G DWDM options limit network operators to 10-15km unless specialized equipment is employed. Since most access network links span up to 80 km, there’s a need for a solution that can deliver greater bandwidth over longer distances without additional specialized equipment.
Enter Precision OT’s groundbreaking pre-compensation ASIC to extend the reach of tunable 25G out to 40km and beyond. The ASIC is highly configurable, modulation agnostic, interoperable and expandable to other data rates.
Precision OT will demonstrate the technology in a TSFP28-40(I) (tunable 25G extended reach module) product demonstration at the SCTE Cable-Tec Expo, held October 16-19 in Denver, Colorado.
