The PWL4100S from Harri is part of the PWRLink II series of 1310nm DFB laser transmitter modules. The PWRLink II transmitter is designed for advanced broadband networks, capable of functioning independently in local distribution networks or working in conjunction with Harri's external modulation optical transmitter series to form a complete fiber optic transmission network.
Application
Hybrid Transmission of Broadcasting Television and Digital Broadcasting
DFB 1550nm hybrid cascade can be used for trunk, ultra-trunk, and interconnection transmission.
A high-quality signal transmission with a bandwidth of 1000MHz can reach a distance of up to 45km.

PWL 41xxS-zz
xx = model number (02 to 15)
zz = Connector Type (AS, AF, US, UF, AE)
Link Performance
Carrier-to-Noise Ratio (CNR)
Please refer to the image above.
C/CSO Note 4
>65dB
C/CSTB Note 4
>71dB
When the optical link loss includes splitter loss, a corresponding increase of 0.1dB in CNR is required for every 1dB of splitter loss.

Comment
Note 1: Unmodulated signals specific to 80 channels in NTSC format, plus a 200MHz wide digital signal at 10dB lower.
Note 2: The optical link refers to the PWL4100S transmitter + 100% fiber + HRM3811 receiver.
Note 3: When a 6dB lower digital signal with a bandwidth of 200MHz is added, the typical CNR value decreases by 0.5dB.
Note 4: This parameter represents typical values for an all-fiber link. Worst-case values: CSO reduced by 1dB, CTB reduced by 2dB.
Note 5: Throughout the entire operating temperature range, the CSO and CTB indicators will vary by 2 dB.
Note 6: SC/APC is the connector type recommended by Harley. Users may specify other types of connectors.
