EMCORE Corp. (NASDAQ: EMKR) says it has enhanced the feature set for the full-band tunable 10-Gbps form-factor pluggable (TXFP) transceiver, to include 40-nm full-band support, a transmitter variable optical attenuator, and flexi-grid compliance.

Based on EMCORE's patented ClearLight fourth-generation external cavity laser (ECL) platform, the TXFP transceiver delivers the highest quality optical signal, wavelength accuracy, and transmission performance, along with best-in-class side-mode suppression ratio (SMSR), according to EMCORE.

Customers can use TXFP transceivers to reduce size, power consumption, and operating expenses by replacing both legacy 300-pin tunable transponders and fixed-wavelength DWDM XFP transceivers.

EMCORE's TXFP supports a full-band of 40 nm (100 x 50 GHz channels), making it the most widely tunable transceiver on the market, the company claims. In addition, it addresses the new International Telecommunications Union (ITU) flexi-grid standard allowing customers to tune onto any frequency grid and address any off-grid frequency. EMCORE also plans to include an optional transmitter variable optical attenuator, which allows customers to remove external attenuators, once again increasing density while reducing overall system cost and complexity.

"The EMCORE TXFP represents the leading-edge in metro and long-haul DWDM network flexibility by delivering the highest level of performance and tuning capability in the smallest available form-factor," commented Jaime Reloj, EMCORE's vice president of business development. "By leveraging our ECL technology and in-house semiconductor manufacturing, we are able to offer our customers performance and features that no one else in the industry can match. Our customers are using the unique features of the EMCORE TXFP such as flexi-grid tuning and highest available SMSR to enable more flexible and cost-effective optical network architectures."
