1310 nm Directly Modulated Laser Transmitter (DMLT-1310)

Data Sheet

The Optilab DMLT-1310 laser transmitter is a reliable and cost-effective solution for HFC, PON and deep fiber applications.

Product Overview

The Optilab DMLT-1310 laser transmitter is a reliable and cost-effective solution for HFC, PON and deep fiber applications. The DMLT-1310 uses a highly linear 1310 nm DFB laser module and an advanced pre-distortion RF drive circuit to deliver 50+ dB of CNR, while maintaining optimal CSO and CTB performance. The DMLT-1310 has a standard transmission range up to 20 km, and is available at output power levels from +6 dBm to +13 dBm. With the best cost/performance ration in the industry, the DMLT-1310 transmitters support up to 75 NTSC analog channels and an additional 60 QAM channels. Contact Optilab for more information.
