Description

The ZL60301 is a v ery hig h-speed transc eiver fo r p arallel fi ber applications . This transce iver performs E/O and O/E

conversions for data transmission over multimode fiber ribbon.

The transmit section converts parallel electrical input signals via a laser driver and a VCSEL array into parallel

optical output signals at a wavelength of 850 nm.

The receive section converts parallel optical input signals via a PIN photodiode array and a transimpedance and

limiting amplifier, into electrical output signals.

The module is fitted with a pluggable industry-st andard MegArray® BGA connector. This provid es ease of a ssembly

on the host board and enables provisioning of bandwidth on demand.

VCCA and VCCB Rx can be connected to the same power supply. However, to insure maximum receiver sensitivity

and minimize the impact of noise from the power supply, it is recommended to keep the power supplies separate

and to use the recommended power supply filtering network on VCCA Rx, see Figure 2.

Thermal Characteristics

There are three options for heat sinks depending on the cooling needs. They are:

1. Direct application without any attached external heat sink

2. Use a generic external heat sink specified by Zarlink

3. Use a customer designed external heat sink

In Figure 10 and Figure 11, the temperature rise and thermal resist ance as a function of air velocity (fre e air velocity

at the top of the module) is shown for option 1 and 2. The thermal resistance is defined as the temperature

difference between the case temperature and ambient flowing air divided by the total heat dissipation of the

module.

Improved thermal properties can be achieved by using a larger heat sink especially if more height is available

(option 3). For this option, a more detailed discussion with Zarlink is recommended regarding heat sink design

attachment materials.

Regulatory Compliance

Eye safety

The maximum optical output power is specified to comply with Class 1M in accordance with IEC 60825−1:2001. In

addition the transmitter complies with FDA performance standards for laser product s except for dev iations p ursuant

to Laser Notice No.50, dated July 26, 2001. No maintenance or service of the product may be performed.

Electrostatic discharge

The module is classified as Class 1 (> 1000 Volts) accord in g to MIL−STD−883, tes t method 3015.7, with regards to

the electrical pads.

Electrostatic discharge immunity

The part withstand a 15 kV (air discharge) and 8 kV (contact discharge) either indirect or directly to receptacle;

tested according to IEC 61000−4−2, while in operation without addition of bit errors.

Electromagnetic Interfe rence

Emission

The electromagnetic emission is tested in front of the module (module fitted with EMI shield), with the module

mounted in a frontplate cutout. The part is tested with FCC Part 15, 30 − 1000 MHz and 1 GHz to 5th harmonic of

the highest fundament al frequency (6.75 GHz), and is specified to be Class B with > 6 dB margin.

Immunity

The electromagnetic immunity is tested without a front panel or enclosure. The module specification is maintained

with an applied field of 10 V/m for frequencies between 10 kHz and 10 GHz, according to IEC 61000 −4−3 and GR−

1089−CORE.

Handling instructions

Cleaning the Optical Interface

A protective connector plug is supplied with each module. This plug should remain in place whenever a fiber cable

is not inserted. This will keep the optical port free from dust or other contaminants, which may potentially degrade

the optical signal. Before reattaching the connector plug to the module, visually inspect the plug and remove any

contamination. If the module’s optical port becomes contaminated, it can be cleaned with high-pressure nitrogen

(the use of fluids, or physical contact, is not advised due to potential for damage).

Before a fiber cable connector is attached to the module, it is recommended to clean the fiber cable connector

using an optical co nnector cleane r, or accordin g to the c able ma nufacturer's instructions . It is also reco mmende d to

clean the optical port of the module with high-pressure nitrogen.

Connectors

For optimum performance, it is recommended that the number of insertions is limited to 50 for the electrical

MegArray connector and 200 for the optical MPO/MTP connector.

ESD handling

When handling the modules, precautions for ESD sensitive devices should be taken. These include use of ESD

protected work areas with wrist straps, controlled work-benches, floors etc.

Link Reach

The following table lists the minimum reach distance of the pluggable parallel fiber optic transceiver for different

multi-mode fiber (MMF) types and bandwidths assuming worst case parameters. Each case allows for a maximum

of 2 dB per channel connec tion loss for patch cables and other connectors.

Link Model Parameters

The link reaches above have been calculated using the following link model parameters and Gigabit Ethernet link

model version 2.3.5 (filename: 5pmd047.xls).
