The Optilab EMLT-1550-SR transmitters are a cost-effective and versatile transmission solution for HFC/
RFoG/PON networks regardless of architecture.The EMLT-1550-SR laser transmitters include a high quality
Distributed Feedback laser (DFB), adjustable ±1.5 nm. The EMLT-1550-SR incorporates a broadband external
modulator and a pre-distortion circuit which allows up to 90 km transmission range, while maintaining a high
OMI level and excellent CSO and CTB performance. The SBS supression setting allows the launch power to be
adjusted from +13.5 dBm to +16.5 dBm, and is available with output power levels from +6 dBm to +8 dBm. The
EMLT-1550-SR transmitter supports up to 77 NTSC analog channels, and because it’s designed to be digitally
ready, it can also be loaded with additional QAM modulated data or HDTV channels making it the best cost/
performance ratio in the industry. Contact Optilab for more information.
