1340-Type Lightwave Receiver
s CMOS (TTL) link-status flag output
s Operation at 1.3 µm or 1.55 µm wavelengths
s Operating case temperature range of
–40 °C to +85 °C
Applications
Operating at 1.1 µm through 1.6 µm wavelengths and at
155 Mbits/s, 622 Mbits/s, or 1.25 Gbits/s, the versatile
1340-Type Receiver is manufactured in a 20-pin, plastic DIP
with a multimode fiber pigtail.
s Telecommunications:
— Inter- and intraoffice SONET/ITU-T SDH
— Subscriber loop
— Metropolitan area networks
s High-speed data communications
Features
s Backward compatible with 1310 receiver family
s Space-saving, self-contained, 20-pin plastic DIP
s Silicon-based ICs
s Single 5 V power supply operation including photo-
current monitor capability
s Exceeds all SONET (GR-253-CORE) and ITU-T
G.958 jitter requirements
s Wide dynamic range
s Qualified to meet the intent of Telcordia Technolo-
gies * reliability practices
s Operates at data rates of 155 Mbits/s,
622 Mbits/s, or 1.25 Gbits/s
s Positive ECL (PECL) data outputs
Description
The 1340-Type receiver is designed for use in trans-
mission systems or medium- to high-speed data
communications applications at data rates up to
1.25 Gbits/s. Compact packaging, along with wide
dynamic range, makes these receivers ideal for both
telecommunications and data communications appli-
cations.
The following three versions of the receiver are avail-
able:
s SONET/SDH compliant with OC-3/STM-1
s SONET/SDH compliant with OC-12/STM-4
s 1.25 Gbits for data applications.

Description (continued)
The SONET/SDH versions of the receiver are fully
compliant with the latest issue of Telcordia Technolo-
gies GR-253- CORE and the most recent issues of ITU
recommendations G.957 and G.958. The 1340-Type
receiver requires only a single 5 V power supply for
operation. All versions of the receiver are characterized
for operation over the case operating range of –40 °C
to +85 °C at the appropriate data rate for each version.
Manufactured in a 20-pin DIP, the receivers use a pla-
nar, rear illuminated InGaAs PIN photodetector that
allows these receivers to be used at wavelengths from
1.1 µm to 1.6 µm. The photocurrent output of the PIN
detector is amplified and converted to a voltage by a
silicon amplifier. A silicon quantizer provides additional
signal amplification, data threshold detection, and
PECL data outputs. The incoming optical signal is cou-
pled into the receiver through a 62.5 µm core multi-
mode fiber pigtail. The outer jacket diameter of the
pigtail is 900 µm. The receiver can be ordered with the
pigtail terminated in an FC/PC, SC, or ST ® optical con-
nector. Other connectors are available on special order.
See your Agere account representative for ordering
conditions and information.
The receiver has differential PECL data outputs and,
depending on the version selected, either differential
PECL link status flag or complementary CMOS link
status flag outputs. The link status flag outputs indicate
the presence or absence of a minimum acceptable
level of optical input signal.
