Eudyna launches next-generation PON and DWDM components

Eudyna Devices Inc of Yokohama, Japan is announcing a range of new products for next-generation passive optical networks (PONs) as well as advanced dense wavelength division mulitplexing (DWDM) applications.

Eudyna has long used its in-house device technologies to provide components for next-generation broadband networks, such as 10Gb/s electro-absorption modulated lasers (EMLs), high-sensitivity PIN and APD (avalanche photodiode) receivers, as well as burst-mode trans-impedance amplifiers (TIAs) for PON applications.

Now, for high-end DWDM applications, Eudyna has applied its device technology to a unique coaxial-style 10Gb/s APD receiver employing a TIA plus integrated automatic gain control (AGC) that offers high gain as well as high linearity. The integrated AGC functionality provides for a very robust optical signal-to-noise ratio (OSNR) performance throughout a wide range of input powers, Eudyna says. The coaxial 10Gb/s APD receiver offers equivalent performance to that of existing coplanar packaged receivers but in a more compact and cost-effective form-factor, the firm claims.

On the transmitter side, Eudyna has developed a full-C-band tunable laser that has now been taken into production. Among its unique features is its capability to deliver output powers of up to 17dBm, which can be advantageous for advanced 40 and 100Gb/s transmission modulation formats such as DQPSK and DP-QPSK. The tunable laser will be offered in an OIF-compliant integrable tunable laser assembly (ITLA) module.

For next-generation PON applications, Eudyna is introducing the ELD5403QK/BH-V/W, which is a high-power 10Gb/s EML laser that fully meets with the emerging IEEE 802.3av 10GBASE-PR-D1,D3 or 10/1GBASE-PRX-D1,D3 standards. The output power is +4dBm minimum, the emission wavelength is 1575-1580nm, and the dispersion tolerance is up to 350ps/nm (corresponding to 20km for single-mode fiber). The generally available laser is provided in an XMD-MSA package with either an LC receptacle (ELD5403QK-V/W) or a fiber pigtail (ELD5403BH-V/W). The temperature range is 0-75°C for the -V version and -40°C to +90°C for the -W version.

Additionally, Eudyna is introducing a TO-can APD receiver for the GPON ITU-T G.984.2 Class C+ application, which builds on the firm's expertise in high-sensitivity APD receivers and burst-mode TIAs. The APD receiver for Class C+ is available for immediate sampling.

“By working closely with our key customers, Eudyna has been able to introduce a range of unique products that address new market needs,” says Jane Li, general manager & executive VP of subsidiary Eudyna USA in San Jose, CA.
