LC-155Bxxxx
155Mbps, SFF LC Duplex Optical Transceiver Module for
Fast Ethernet, ATM, SONET/SDH STM-1/OC-3
Features：
z
Full Compliance with the Optical Performance
Requirements of the ATM 100Mbps and 100
Base-FX Version of IEEE 802.3u.
z
z
Multisource 2x5 package styles with LC
Receptacle.
Single 5V（LC-155B1 and LC-155B3 Series）or
3.3V（LC-155B2 and LC-155B4 Series）Power
Supply.
z
z
PECL Differential Inputs and Outputs.
PECL（LC-155B1 and LC-155B2 Series） or
TTL（LC-155B3 and LC-155B4 Series）
Receiver Signal Detect Indicator.
z
Wave Solder and Aqueous Wash Process
Compatible.
Description：
The receiver sections utilize InGaAs PIN
photodiodes coupled into custom silicon
The LC-155Bxxxx series from DELTA are SFF
（Small Form Factor） optical transceiver modules
a
transimpedance preamplifier IC. These are
packaged in the optical subassembly portion of
receiver.
designed expressly for high-speed communication
applications that require rates of up to 155Mbps.
They are all compliant with the SONET/SDH
standards.
These PIN / Preamplifier combinations are coupled
into a custom quantizer IC which provides the final
pulse shaping for the logic output and the Signal
Detect function. The data output is differential. The
signal detect output is single-ended.
The LC-155Bxxxx transceivers are supplied in 2x5
DIP package style with duplex LC connector and
are fully complaint with SFF Multi Source
Agreement （MSA）.
Application：
All LC-155Bxxxx series can meet Class-1 eye
safety standard and effective distance depends on
ITU-T G.957 standard or power penalty.
z

z
Single-mode Fiber Backbone Links.
Fast Ethernet and ATM Compatible.
Single-mode Fiber Media Converter.
The transmitter sections utilize 1310nm Edge
Emitting InGaAsP Laser Diode. This Laser Diode is
packaged in the optical subassembly portion of the
transmitter section. A custom silicon IC that
converts differential PECL logical signals into an
analog LD driving current then drive it.

When system Vcc is 5V, the resistors
are as below:
z
R1=150Ω
R2=R3=191Ω；R4=R5=68Ω
R6=R7=270Ω；R8=130Ω；R9=82Ω

When system Vcc is 3.3V, the
resistors are as below:
R1=150Ω
R2=R3=130Ω；R4=R5=82Ω
R6=R7=150Ω；R8=82Ω；R9=130Ω
z
z
R10, R11, R12 depend on SerDes IC
specification.
For getting better EMI performance,
the Tx Vcc and Rx Vcc should isolate
each other as left photograph.
