V23826-K15-Cxx, V23826-K15-Cxxx Product Specification – August 2004
Description
The Finisar single mode transceiver is based on and compliant to the Physical Medium
Depend (PMD) sublayer and baseband medium, type 1000 Base-LX (long wavelength)
as specified in IEEE 802.3 and Fibre Channel FC-PI Rev. 13 100-SM-LC-L.
The appropriate fiber optic cable is 9
µm
(mode field diameter) single mode fiber (up to
10 km) with Duplex SC connector.
The Finisar single mode transceiver is a single unit comprised of a transmitter, a
receiver, and an SC receptacle. This design frees the customer from many alignment
and PC board layout concerns. The module is designed for low cost LAN, WAN and
Gigabit Ethernet applications. It can be used as the network end device interface in
mainframes, workstations, servers, and storage devices, and in a broad range of
network devices such as bridges, routers, intelligent hubs, and local and wide area
switches.
This transceiver operates at 1.0625 and 1.3 Gbit/s from a single power supply (+5 V or
3.3 V). The full differential data inputs and outputs are PECL compatible.

Functional Diagram
The receiver component converts the optical serial data into PECL compatible electrical
data (RD+ and RD–). The Signal Detect (SD, active high) shows whether an optical
signal is present.
The transmitter converts electrical PECL compatible serial data (TD+ and TD–) into
optical serial data.
The following versions are available:
1 AC/DC Transceiver: Tx is AC coupled. Differential 100
Ω
load. Rx has standard PECL
output and is DC coupled.
2 AC/AC TTL Transceiver: Tx and Rx are AC coupled. Tx has differential 100
Ω
load.
Signal Detect is TTL compatible.
3 DC/DC Transceiver: Standard PECL inputs and outputs Tx and Rx are DC coupled.
This version contains an Input Signal Monitor (ISM) which switches off the transceiver
if a continuous low level is applied at Data Input.
4 AC/AC PECL Transceiver: Tx and Rx are AC coupled. Tx has differential 100
Ω
load.
Signal Detect is PECL compatible.
