Overview

Copper Ethernet SFPs

MRV offers three models of Ethernet SFPs for copper media

applications.Two of the models support Gigabit Ethernet functionality,

and the third one provides unique 10/100 Fast Ethernet solutions.

The SFP-GC-R model supports Gigabit Ethernet with a 1000Base-

T interface, and it is designed for Layer 1 network devices that do

not incorporate an Ethernet MAC. The SFP-GA-R is designed for use

in Layer 2 and above devices such as switches and routers that do

incorporate an Ethernet MAC. It supports Gigabit Ethernet with an

auto-negotiating 1000Base-T interface.

SFP-GC-R and SFP-GA-R

models each support MDI/MDI-X auto-detection and jumbo packet

sizes over 9,600 bytes.

Installed into MRV products with an available SFP port, the SFP-GC-R

plug-ins provide a simple and cost-effective way to merge copper

and fiber network segments.

The SFP-GA-R gives network administrators greater flexibility in

configuring their SFP-enabled switches and routers, allowing them

to use less expensive copper cabling and interfaces for links of 100

meters or less.

The SFP-GC-R and SFP-GA-R do not convert between edge devices

of different speeds or duplex mode. Connected edge devices must

operate at the same speed and duplex mode to communicate. An

edge device that supports auto-negotiation may require specific

interface settings for fixed Gigabit Ethernet speed and duplex mode

operation.

The SFP-SW10/100R is a unique Fast Ethernet 10/100 Base-TX to 100-

FX (system side). It offers auto-negotiation with speed and duplex

matching as well as MDI/MDI-X auto-detection. It supports transport

of jumbo packets up to 1,600 bytes.

The SFP-SW10/100R can translate between edge devices of different

speeds or duplex mode. Connected edge devices may operate at

different speeds and duplex modes.
