Notes:
1. Measure at 2^7-1 NRZ PRBS pattern
2. Transmitter eye mask definition.
3. Measured with Light source 1490nm, ER=9dB; BER =<10^-12 @PRBS=2^7-1 NRZ
4. When LOS de-asserted, the RX data+/- output is High-level (fixed).
What is CSFP?
CSFP (Compact Small Form Factor Pluggable) is a Compact SFP, which is based on the popular SFP package, and develops a more advanced and Compact CSFP package. By using a two-channel, four-channel design, CSFP USES the existing SFP universal interface, but reduces the external dimensions to one half and one quarter of the existing industry standard, and can flexibly configure the number of channels through combination. If the traditional discrete component scheme continues, it will be technically difficult to achieve the above functions. CSFP combined with high-integration photoelectric integration technology, on the basis of having all the technical advantages of SFP, greatly reduces the external size of optical transceiver module and optical system equipment, significantly increases the communication port density and data throughput, and reduces the system cost, which is expected to play a big role in the data communication market.
CSFP has rates of 155M, 1.25g and 2.5g
