5. Function & Application
5.1. Interconnecting Media Converters
When connecting with other media converters, it is required to comply with the specific
connecting requirements according to the following table. Otherwise, link faults or
abnormal data transmission will occur.
Host Site Remote Site
RC316-FE-S1 RC315-FE-S1
RC316-FE-S2 RC315-FE-S2
5.2. Connecting MC with Other Devices (at RJ45 Port)
1. RC315/RC316-FE series copper-to-fiber media converters have the function of “MDI
/MDIX auto-negotiation”, so both straight-through and crossover cables can be used to
connect with other equipment.
2. When RJ45 interfaces of RC315/RC316 series media converters work in the forced
status, the “MDI/MDIX auto-negotiation” function may fail. So it is suggested that the
following connection types on the forced status adopted.
Media Converter Other Equipment RJ45 Cable Type
Media Converter Switch Straight-through
Media Converter HUB Straight-through
Media Converter Router Crossover
Media Converter Network Interface Card Crossover

5.3. Full Duplex Configuration (RJ45 Port)
5.3.1. RC315/RC316-FE Series RJ45 Interface Auto-negotiation
When the RJ45 interface of RC315/RC316 media converter is configured to
“auto-negotiation”, the copper port/RJ45 of other network equipment must also be
configured to “auto-negotiation” to ensure normal data transmission. If other equipment is
working in forced status of full duplex mode, the media converters shall be fixed to “Full
Duplex Mode”.
5.3.2. RC315/RC316-FE Series RJ45 in Forced Status
When RC315/RC316 series media converter is working in forced status, the RJ45 duplex
mode configuration of other network equipment must complies with the following table, to
ensure proper data transmission.
Media Converter
RJ45 Mode
Other Equipment
RJ45 Mode
100M/Full Duplex 100M/Full Duplex
100M/Half Duplex 100M/Half Duplex
10M/Full Duplex 10M/Full Duplex
10M/Half Duplex 10M/Half Duplex
5.4. Connection with Other Equipment (at Optical Port)
Several mandatory conditions are required:
1. The same bit rate
2. Matched optical power
3. Fast Ethernet protocol (IEEE 802.3u Fast Ethernet)
