3.2.2 Installation of XGL-EFMF(B)
[Fig. 3.2.2] Installation of XGL-EFMF(B)
The maximum cable length of segment in 100BASE-FX system is 2km (distance between
module and optical switch). In case of XGL-EFMF(B), refer to SFP specification. Let the
module’s Tx cross-connected with the optical switch’s Rx, and the module’s Rx with the optical
switch’s Tx.
1) Since the optical cable is vulnerable to impact, pressure, folding and pulling, pay good attention
to its treatment.
The optical contact between the connector and the end of the cable may have communication
errors if contaminated, which may result in unavailable communication.
If the cable is installed outdoors, additional countermeasures are required to protect the cable
suitably for the installation environment.
