Choosing A Transceiver For A 10 Gb/S Link - Cailabs AROONA-STAR Manuel D'instruction

C. Choosing a transceiver for a 10 Gb/s link
Choosing a transceiver type is based upon the complexity of
the upgraded multi-mode link (i.e. the number of concatenated
segments to obtain the link), its length and the analysis of the
reflectometry measurements carried out (see section "4.1B.
1 segment (simple link) with
OTDR OK
1 segment (simple link) with
OTDR warning
2 to 4 segments (standard
link) with OTDR OK
warning
4 segments (complex link)
with OTDR OK or warning
Note:
10GBASE-LR = 10Gb/s with extinction ratio ~3.5 dB (DFB/
DML)
10GBASE-ER = 10Gb/s with extinction ratio ~8 dB (EML)

Note: These transceiver recommendations ensure that
the upgraded link operates optimally. Selecting unsuitable
transceivers (for example 10GBASE-LR transceivers instead
of the recommended 10GBASE-ER on a link configuration)
does not guarantee the correct operation of the link.
