• 10G Ethernet

• 10X Fibre Channel

Finisar’s DM80-01 butterfly transmitter module employs proprietary Chirp Managed

Laser (CML

) technology and has been specifically designed to transmit 10Gb/s data

over physical distances up to 120km. The module is comprised of a directly-modulated

DFB laser chip and a co-packaged proprietary optical spectrum reshaper (OSR) passive

optical element. The OSR component also provides a frequency locking function and

allows operation on the ITU-T channels within ±2.5GHz with coverage across both C-

band and L-band for DWDM versions. Also included in the standard butterfly footprint

are 2 photo-detectors for power control and wavelength locking, together with 2 TECs for

temperature stabilization. Key specifications for the optical and electrical characteristics,

physical requirements, environmental conditions and reliability/quality requirements are

detailed in this document.

Note: Long version of this document with more detailed optical and electrical parameter

specification is available upon request.

I. Internal Optical Layout

Figure 1

The DM80-01 module uses a 10Gb/s directly modulated DFB chip co-packaged with an

optical spectral re-shaper (OSR) element as shown in Figure 1. An optical isolator is

included between the DFB and the OSR while a beam-splitter component and 2

photodetectors are configured to allow frequency locking. Lens#1(L1) is used to

collimate the DFB laser output and pass the beam through the splitter and OSR, prior to

coupling into single-mode fiber using Lens#2 (L2). A second isolator is included in the

fiber pigtail to minimize the effect of external back-reflections on module performance.

II. Control Method

The schematic in Figure 2 shows the key components and control loops that are used to

operate the module. The output power of the DFB is monitored by photodetector PD1.

Photodetector PD2 monitors the back-reflection from the OSR. The photocurrent ratio

from the two detectors is used to lock the relative spectral locations of the laser and the

OSR via temperature control of the DFB using TEC#1. A second TEC (TEC#2) controls

the temperature of the OSR and locates the operating point of the OSR on the ITU grid

for DWDM applications.

Product code

For the product specified in this document, the proper product code shall be:

DM80-01-3 ( or -4) -xxxx-3-LC-yyyy

This product code should be specified when placing a purchase order.

• “01” indicates a butterfly box module as specified in this document.

• “3” indicates the laser wavelength can be tuned over a sub-band to cover 8 ITU-T

channels with 50GHz spacing; -“4” indicates the laser wavelength can be tuned

over a sub-band to cover 4 ITU-T channels with 100GHz spacing.

• “xxxx” is the channel ID as specified in Table 9 and Table 10. For 4 X 100GHz

option (-(-“4” for the wavelength selection field), “xxxx” indicates a sub-band

which consists of channel “xxxx”, 2 adjacent 100GHz channels on the longer

wavelength (lower frequency) side, and 1 adjacent 100GHz channel on the shorter

wavelength (higher frequency) side. Example: channel “9230” for this option

indicates a sub-band consisting of 4 channels on ITU-T 100GHz grids at

frequencies of 192100GHz, 192200GHz, 192300GHz, and 192400GHz. For 8 X

50GHz option (-“3” for the wavelength selection field), “xxxx” indicates a sub-

band which consists of channel “xxxx”, 4 adjacent 50GHz channels on the longer

wavelength (lower frequency) side, and 3 adjacent 50GHz channels on the shorter

wavelength (higher frequency) side. Example: channel “9230” for this option

indicates a sub-band consisting of 8 channels on ITU-T 50GHz grids at

frequencies of 192100GHz, 192150GHz, 192200GHz, 192250GHz, 192300GHz,

192350GHz, 192400GHz, and 192450GHz.

• “3” indicates modulated output power range is >4dBm. Please contact Finisar if

different power level is needed.

• “LC” indicates the fiber connector is LC type. FC and other connector types are

also available.

• “yyyy” indicates any special customized request and need to be agreed with

Finisar prior to ordering
