S.CON1 Single Channel TX/FX Converter

1 ─Overview

The SCON family products are 10/100Base-TX –FX buffered Media Converters.

They provide network extension over MM fiber (up to 2Km) and up to 150Km over

SM fiber in any network architecture (even with repeaters).

SFS (Single-Fiber-Strand) versions of the S.CON make it a superb choice for

suitable installations saving 50% of the entire cable plant

Managed SNMP models are also available: SCON1M models.

A media-converter may be defined as a device connecting two active network

components point-to-point over a media that is different from the ports of at least one

of these devices.

While Media Converters are considered part of the cable plant, in many cases they

must be remotely managed as any other network device. In particular this is true in

mission-critical, fully managed networks as well as in networks dispersed over large

areas to allow efficient control and maintenance.

While vendors offer such feature for large chassis based systems only, the need for

management is more intense in single channel devices, being deployed away from

the main wiring closets. Out-of-band management assures independence of the

control channel for enhanced system reliability.

An ideal media-converter should be a transparent element in the network, and its

ports may be considered as integral parts of the devices interconnected by it.

The IEE802.3u standard defines network span in terms of distances and bit times.

Conventional 100Base-TX/100Base-FX media-converters are based on repeater

technology, and they form a part of the collision domain created by the

interconnected devices. Therefore, the delay they introduce in the network severely

affects the allowed distances. Furthermore, if two class II repeaters (i.e., 2 hubs) are

already present in the same collision domain, then the use of a conventional

converter is not allowed as the repeater count may - in such case - exceed the limits.

In all other cases, meticulous PDV (Path Delay Value) must be performed prior to

establishing the possible distances for both the fiber optic (F/O) and copper

segments.

The S.CON family series implement a non-repeater, full re-timing design. It creates a

Buffered Media Domain (BMD) over the F/O link, thereby eliminating all the above-

mentioned limitations. The BMD created by two S.CON devices always operates at

maximum performance - 100Mbps/Full Duplex - while interconnected devices may

operate at different rates and modes.

The S.CON1 supports the Far End Fault (FEF) feature.

Far End Fault occurs when the signal detection is logically false from the receive

(incoming path) fiber port. When the S.CON1 detects a F/O Link Loss condition, the

unit will automatically send a Far End Fault signal to the remote device (on it

outgoing path). The remote device should support the same FEF feature and it will

indicate a Link Loss as well. (Refer to section 8 for more details). The S.CON1

supports bi-directional Fault Propagation mechanism (FO>TP and TP>FO). When

the S.CON1 senses a loss of F/O Link, it will automatically cut its TP port link. If the

S.CON1 unit is connected to a Master Unit, which does support Fault Propagation,

the latter will sense the loss of the F/O link and it will deliberately cut its TP port. If the

S.CON1 TP port link fails, the FP will cut the F/O link port (Refer to section 12 for a

detailed description).

2 ─Planning your network with S.CON1

This chapter will guide you through network planning in order to obtain maximum

benefit - in terms of performance and functionality - from the S.CON converter and

other network devices. For specific instructions regarding the S.CON setup, consult

section 11 – "DIP Switches setting”.

Any networking device may connect to the copper port of the S.CON converters:

switches (of any type), hubs of any type (including 10Base-T!) or workstations (10 or

100Mbps).

While copper segments distances (between the device and the S.CON and between

such device and another device) reach their maximum at 100m/330ft, the F/O

segment (multi-mode fiber) may be extended to 2000m (6500ft) and much more

over single-mode fiber. (Up to150Km). Single Fiber Strand (15-20 Km) models can

be deployed saving 50 % of the cabling plant.

As an S.CON1 device is only slightly more expensive (if at all) than a plain 100Base-

FX transceiver (and certainly less expensive than an integrated 100Base-FX up-link

module in any of the interconnected devices), it is highly recommended to use the

typical configuration below: extra benefits are obtained at little or no additional cost!

Additional benefits are obtained due to the implementation of the BMD (Buffered

Media Domain).

When the F/O link connects two hubs, S.CON1 not only converts media but also

splits the network into two segments, which reduces loads and collisions!

Furthermore, hubs operating at two different speeds (10Base-T and 100Base-TX)

may be interconnected, in which case the S.CON1 now acts as a rate converter as

well.

By using the SNMP managed version, S.CON1M devices, the entire network (see the

drawing in the next page: “Typical Network Configuration”) can be monitored by

means of the SNMP manager station located in the Headquarters building.

S.CON1 Single Channel TX/FX Converter

Typical Network Configuration

This network can be monitored and controlled (if the remote attached devices

are S.CON1M units) from any SNMP management station running popular

management platforms (e.g. FibroLAN MetroView, HP OpenView, SNMPc, etc)

S.CON1 Single Channel TX/FX Converter

General Description

All S.CON models have identical functionality and performance. Therefore, any

description or feature of one model refers to all other types.

The RJ-45 port operates in Auto-Negotiation mode: It may operate in 100Base-TX or

10Base-T and in both FDX and HDX modes, depending on the type of device to

which it is connected.

The TP port is a shielded RJ-45 port, cat.5, and 100m. The port can operate as an

MDI-II or MDI-X port depending on the MDI-II /MDI-X selector

The S.CON1 is equipped with an MDI-II/MDI-X selector on the front panel to allow

connection of either a switch/hub or a station, allowing the use of either a straight or

cross-twisted pair cable.

The F/O port supports 100Base-FX transmission in both FDX and HDX modes.

The conversion process creates a BMD, allowing unprecedented functionality and

performance. The F/O port is setup by default to operate at 100Mbps FDX.

For optimized set-up, each S.CON unit is equipped with an array of 7 positions DIP

switches accessible from the front panel. (MODE SETUP).

The device provides extensive diagnostics and a status display with 7 high visibility

LEDs for each S.CON device.

SCON.1 models Power Supply (including –48 models)

The system is equipped with a powerful power supply (100 - 240V universal input or

–48VDC). A front panel LED indicates the power status.
