V23809-E1-E30, 1300 nm ESCON
Parallel Transceiver
2
Semiconductor Group
DESCRIPTION
The Siemens ESCON/SBCON optical device, along with the
ESCON/SBCON optical duplex connector, is best suited for
high speed fiber optic duplex transmission systems operating
at a wavelength of 1300 nm. The system is fully compatible
with the IBM ESCON standard and the ANSI SBCON standard.
The ESCON parallel transceiver includes a transmitter, a receiver,
a clock recovery function and serial/parallel interfaces. It is
designed for data rates of up to 300 MBaud. A non-dissipative
plastic receptacle matches the ESCON duplex connector.
The inputs/outputs are TTL compatible and the unit operates
from a single power supply of 4.5 V to 5.5 V.
The optical interfaces of the transmitter and receiver have stan-
dard 0.7” spacing. Receptacle and connector have been keyed
to prevent reverse insertion of the connector into the recepta-
cle. After proper insertion, the connector is securely held by a
snap-in lock mechanism.
The transmitter converts parallel electrical TTL input signals into
an optical serial signal at data rates of between 100 and 300
MBaud. The receiver performs clock recovery on the incoming
data stream and converts data into parallel output.

and Fig.26. Spectral width must be considered.
8. Measured at 200 MBaud with Jitter Test Pattern (see page 4). In the
Test Pattern are five positive and five negative transitions. Measure
the time of the 50% crossing of all 10 transitions. The time of each
crossing is then compared to the mean expected time of the cross-
ing. Deterministic jitter is the range of the timing variations.
9. RMS value measured with 1010 pattern. Peak-to-peak value is deter-
mined as RMS multiplied by 14 for BER 1E-12.
10.Extinction ratio is the logarithmic measure of the optical power in
the OFF state (P
