FIBER OPTIC CONVERTERS
The Fiber Optic Converters can achieve a data rate of up to 250 Mbps. They
also have built-in diagnostic procedures (local and remote loopback) that
comply with the ITU-TSS (CCITT) V.54 standard. Use the front-panel switch
to determine which type of loopback you want and perform these procedures
with a Bit Error Rate Tester (BERT) connected to the Converter in place of
the local device.
The Converters support unipolar two-level codes, such as NRZ, NRZI, RZ,
and biphase (CDP, Manchester), but not bipolar (multi-level) codes (such as
AMI or HDB3) or uncoded signals.
CAUTION!
Use the Fiber Optic Converter-850NM (our product code IC350A) to
convert to and from multimode cable carrying light at 850 nm. Use the
Fiber Optic Converter-1300NM (our product code IC351A) to convert to
and from multimode cable carrying light at 1300 nm.
Neither type of
Converter will work with multimode cables designed for the other type’s
wavelength.
