Copper-to-Fiber Media Converters
with IP- Less™ Remote Management
Overview
Once confined to the LAN or campus environment, Ethernet has been
adopted into the growing modern optical infrastructure. It now covers
everything from the core of the MAN to the last mile access networks
for FTTH (home), FTTS (subscriber), and FTTB (business). Simplicity,
scalability, and wide availability of interoperable equipment makes
Ethernet a poplular choice for providing seamless end-to-end optical
connectivity. Wide acceptance and growing demand reinforces optical
Ethernet (OE) as the most cost-effective network infrastructure to deploy
and maintain.
The Fiber Driver Copper-to-Fiber converter family matches copper
Ethernet and Fast Ethernet media to a range of single-mode, multi-mode,
and single fiber optical options. The EM316ERM module set connects
to 10Base-T Ethernet devices. The EM316FRM modules connect to
10/100Base-TX devices. The EM316EFRM modules connect to either
standard Ethernet or Fast Ethernet devices, and includes speed auto-
negotiation and automatic MDI/MDI-X detection for matching duplex
mode communications.
At the heart of the IP-Less™ technology, the onboard “Micro Agent”
processor separates the management channel from the data channel.
Used in pairs, the media converter modules transmit a logically separate
(out of band) management channel that shares the same physical
fiber path as the data channel. This channel separation ensures full
data bandwidth availability while providing complete Fiber Driver
management support including security and immunity from data
channel condition variances.
The copper-to-fiber media converter family features a standard RJ-45
Ethernet port. The EM316EFRM module includes auto-negotiation and
MDI/MDI-X duplex detection as well as manual configuration. Duplex
detection allows use of either straight-through or crossover cables for
Ethernet connection to an external device.
