3 GENERAL DESCRIPTION 3.1 Introduction The optical transmitter ES10/ES26 represents a family of externally modulated 1550 nm DFB laser transmitters. These products have been developed to fulfill the requirements of modern Hybrid Fiber Coax networks for the transmission of CATV, cable phone, cable data signals and SAT-IF (only ES26). There are currently 2 different base versions available: • ES10L for applications with moderate fiber length of < 50 km This version features a SBS threshold of 16.
A Liquid Crystal Display (LCD) provides information about actual settings and properties. 6 push buttons are used to enter data locally. The background light of the LCD is switched on automatically, when a push button is pressed. The ES10/ES26 provides plug in power supply modules. The minimum configuration is one power supply + fan module together with a redundant fan-only module. Optionally two power supply + fan modules can be used for improved reliability.
RS 232Interface Ethernet Interface Liquid crystal display + push buttons RS485 Interface CSO Detection RF - Input Input Monitor RF - Monitor Fig. 3.2.1: ES10 Block Diagram The central core of the transmitter is the electrooptical modulator working as a Mach-Zehnderinterferometer. The light from the laserdiode is coupled into an optical strip waveguide.
To suppress the Stimulated Brillouin Scattering (SBS) the wavelength spectrum of the optical signal is broadened. Two technologies are used: • Broadening the optical spectrum by modulating the laserdiode operating current • Broadening the optical spectrum by driving an optical phase modulator These SBS circuits are mandatory to avoid stimulated Brillouin scattering in optical fibers and allow operation with optical amplifiers feeding at least +13 dBm of optical power into standard single mode fibers.

3.3 Principle of Element Management The interface configuration for Element Management or Network Management systems is shown in the next two figures for the ES10XLa/ES26XLa with embedded NEC (network element controller = SNMP Proxy Agent) and the ES10L/ESXLb. Fig. 3.3.1: a) EMS / NMS Interface of ESxb b) EMS / NMS Interface of ESxa The ES10XLa/ES26XLa versions (ref. to Fig. 3.3.1 a) contain an embedded network element controller (NEC) which works as a SNMP Proxy Agent.
The picture below explains how the ES10XLa / ES26XLa interfaces to other devices and a SNMP EMS. Fig. 3.3.2: The ES10XLa interfacing with other equipment and a SNMP EMS. In this figure the ES10XLa/ES26XLa with embedded NEC (upper right corner) is connected to other (BKtel) devices via the RS485 interface. In the example there is an optical amplifier OVxxxxb (without embedded NEC) in 19”-1RU housing, similar to the ES10/ES26, and in total 4 subracks interfacing to the RS485 bus.
As soon as the Webbrowser establishes the link to the NEC-E with the correct IP address, all chassis devices connected to the RS485 bus are listed on the first page. Clicking on a device listed in the menu “Devices” leads to further webpages, which allow supervision and adjustment of the selected device. 3.3.

4.2 I/O Ports of ES10/ES26 (Option for a-versions) The ES10XLa/ES26XLa from hardware release 2.0 (ref. to 11.1) is optionally equipped with 2 general purpose I/O and 4 input-only binary mode ports. The ports can be configured via the Webserver (HTTP) interface. The schematics of these ports are given below. Fig. 4.2.1: Schematics of I/O port Fig. 4.2.2: Schematics of input-only port Notes: • The maximum voltage applied to all ports should be not below GND level and should not exceed +5 VDC.
The ES10XLa/ES26XLa uses an 8 pin Mini-DIN connector for external Input/Output handling. The connector is located on the backside of the device near to the NMS RS485 Master connector. Fig. 4.2.3: ESXLa rear side connectors Fig. 4.2.4 shows the view on the 8 port mini-DIN connector Fig. 4.2.4: 8 pin mini-DIN connector pinout The mini-DIN connector pins are used as described in the following table. Function in ES10XL/ES26XL (a-versions only) Pin Number Comments of mini-DIN connector GND 2 Ground +5.
Notes: • On pin 1, there is a 5.1 VDC (+/-5 %) supply voltage available for feeding an external interface box, which e.g. could contain optocouplers or relays, external sensors etc.; the current sinked from this port should not exceed 80 mA. • I/O #0 is directly related to the transmitter. If the port is used as an output, alarms related to the transmitter can be accessed on this output. If the port is used as an input it enables easy redundancy switching between two redundant ES10XLa.

5 OPERATING THE ES10/ES26 5.1 Handling Optical Components 5.1.1 Handling Optical Fibers The smallest permissible bending radius for fibers used to connect HFC devices is 30 mm (diameter of 60 mm). A smaller radius significantly attenuation of the fiber optic cables and even damage the fibers. Therefore, handle the fibers carefully, especially during installation. 5.1.2 Connecting and Disconnecting Optical Connectors 2 Please proceed as follows connecting optical links: 1.
Laser Radiation If you inspect the front of the plug when the equipment is switched on, there is a danger of damage to your eyes. WARNING NOTICE Therefore, always switch the equipment off for this kind of work. Use a measuring device to ensure that there is no laser beam emission from the fiber. Do not touch the surface with your fingers when cleaning. Plug pins with imprinted grooves on the front must only be daubed clean using a brush.
5.1.3.1 Cleaning the plug pins 1. Fold the cleaning cloth three times. The cloth pad now constitutes an eight–layered cloth. 1 2 3 2. Moisten the folded cloth a little using the cleaning fluid, ensuring that a dry area remains. 3. Place the front surface of the connector, or the connector shaft on the moistened part of the cloth, pressing lightly. Let the cleaning fluid work into the dirt for a short time. 4.
5.1.3.2 Cleaning the connector of the transmitter device NOTICE Cleaning the device connector(s) requires device opening. Since device opening may extinguishes when doing so! damage its function, warranty Therefore, cleaning the connector may be only performed by BKtel manufacturing engineers or BKtel repair engineers! Please send device to BKtel in case you assume dirty device’s bushings and/or connectors! NOTICE 3 Only clean device’s bushing and bushing case when no connector is connected.
5.2 Power-Up Sequence • Be sure that the ES10/ES26 is going to be put into operation under the specified environmental conditions. Avoid temperature shocks after transportation of the ES10/ES26 and allow sufficient time to accommodate with the environmental conditions at the operating site. • If not already realised install the appropriate power supply + fan modules, respectively fanonly modules.

The built-in RF power meter controls the rms input level and indicates its status at the INPUT LED. There are two RF modes, which can be selected: 5.3.2.1 RF Mode “AGC-on” This mode is the recommended mode for standard operation! As long as the input level is within the working range of the transmitter (specified by the table above), the transmitter will itself adjust the optimum gain. Then, the specified total rms modulation index OMItotrms, will be automatically obtained by the AGC.
5.3.2.2 RF Mode “AGC-off” In this mode, which is for experienced users only, the user has the flexibility to change the gain of the internal RF amplifier by at least -6 … +6 dB according to his individual requirements. However, this adjustment is changing the RF input sensitivity. The OMItotrms is measured for the applied input signal and the selected gain and can be monitored on the LCD display or via the Ethernet interface.
5.3.5 ITU frequency adjustments in DWDM applications (XL only) The ES10/ES26 offers the feature to tune the optical frequency (respectively wavelength) of the transmitter by +/-100 GHz in steps of 50 GHz in order to enable DWDM applications. The tuning can be performed via the buttons on the front panel or via the Ethernet interface. 5.3.6 Optical power on /off The transmitter can be configured as a back-up transmitter with optical output power off.
It is recommended to use the high SBS threshold settings (> 16.5 dBm) for distances below 65 km, and the lower SBS thresholds for longer distances. The SBS threshold can be selected in 0.5 dB steps between 13.0 and 19.0 dBm for optimization of the SBS performance in individual applications and link characteristics. 5.

OFF / Standby. By selecting this mode the ES10/ES26 will operate with optical output power switched off. However, the laser temperature is still kept at the operating temperature by driving the peltier cooler enabling a fast switching-on time. Additionally the RF input monitor is operating.
(master/slave mode, ref. to 7.17) this feature will automatically switch from the master TX + EDFA to the slave TX + EDFA. In this case the I/O No. 0 ports of both ES10/ES26 have to be connected and the master/slave settings according to 7.17 have to be chosen. Note: The requirements for an alarm condition can be set by adjusting the alarms thresholds as explained in 7.18. 7.
7.17 Changing I/O Port’s Mode Fig. 7.17.1: Setting the I/O port mode of ES10/ES26 The I/O port No. 0 can be set either to be an output port, where 4 modes of operation are available: • active low • active high (default = factory setting) • redundant master (irreversible) or • redundant master (fallback) or being an input port, which implies the redundant slave mode. The table below shows the mode of operation and the impact on I/O port No.
Mode of operation Description I/O port No. 0 Active low In case of any alarm, which arises in case Output, active low any of the alarm thresholds has been reached or due toan internal error the I/O port becomes low. Active high In case of any alarm, which arises in case Output, active high any of the alarm thresholds has been (Default = factory reached or due to an internal error the I/O setting) port becomes high.
Application: Automatic redundancy switching of 2 ES10/ES26 located side by side: • Connect a cable between the master and the slave ES10/ES26 connecting both I/O No. 0 ports and GND. • Set the master ES10/ES26 in one of the two Redundant master modes • Set the master ES10/ES26 I/O port mask to the desired mode.
7.18 Setting an Alarm/Warning Mask for I/O Port #0 The ES10/ES26 allows setting an alarm/warning mask, which determines whether a warning or alarm is shown or suppressed on I/O port #0. The menu is shown in the picture below.
