The JDSU CF2 Series OC-3 transceiver is a duplex-LC transceiver designed for use
in SONET OC-3 and SDH STM-1 applications. It operates with a single 3.3 V
power supply. The unit conforms to the industry-standard 2x5 and 2x10
footprints and meets the mezzanine height requirement of 9.8 mm.
Each transceiver consists of an optical subassembly housing both the transmitter
and the receiver, and an electrical subassembly. All are packaged together with a
top metal cover and bottom shield.
The optical subassembly comprises two parts: the transmitter side has a high-
performance 1300 nm Fabry-Perot (FP) or 1550 nm distributed feedback (DFB)
laser and back facet monitor. The receiver side has an InGaAs PIN and a
preamplifier.
All CF2 Series OC-3 transceivers also include a signal detect circuit, which
provides either a Positive Emitter Coupled Logic (PECL) or TTL logic high output
when a usable input optical signal level is detected.
Compliance
• Compliant with SONET OC-3 and
ITU-T G.957 SDH STM-1
specifications (155 Mb/s data rate)

Electromagnetic Interference (EMI)
Most equipment designs utilizing high-speed transceivers will be required to meet the requirements of the FCC in the United
States, CENELEC EN55022 (CISPR 22) in Europe, and VCCI in Japan.
The CF2 OC-3 transceivers, with their shielded design, perform to the specified limits to assist the designer in the
management of overall equipment EMI performance. They meet the FCC Class B limits.
Immunity
The CF2 OC-3 transceiver has been designed to provide good immunity to radio-frequency electromagnetic fields. The metal
cover, chassis, and internal and bottom shields constitute the key components to achieving good electromagnetic
performance (EMC).
Eye Safety
The CF2 OC-3 1300 nm and 1550 nm laser-based transceivers have been designed to meet Class 1 eye safety. They conform
to FDA 21CFR1040.10 and 1040.11 and IEC 60825-1.
