PRODUCT UPDATE
Yokogawa Europe releases OTDR module for remote fibre test systems
The new AQ7277B from Yokogawa Europe is a high- performance optical time- domain reflectometer (OTDR) module for use with remote fibre-test systems. Today it is more important than ever for telecom carriers to proactively monitor and maintain their fibre networks, according to Yokogawa. Huge penalties in service level agreements and quality of service commitments give carriers the financial incentive to invest in maintaining their fibre networks. Continuous monitoring of optical fibre lines using OTDR technology can speed up the identification and location of failures by detecting increased loss in the fibre line, and facilitates restorative maintenance. The hardware of the AQ7277B OTDR module is based on Yokogawa’s established AQ7280 OTDR, with its superior optical performance in terms of short dead zone (0.6 m typical) and high dynamic range (up to 50 dB). Moreover, it is is 60 per cent smaller in size than its predecessor, for ease of integration into the remote fibre test system. The dimensions are 230mm × 50mm × 140mm, and it weighs about 1kg.
XKL adds DQT10 transponder to its DQM10 family
There are two models in the AQ7277B family, both equipped with an Ethernet (10BASE-T/ 100BASE-TX) interface as standard. The AQ7277B-B01 takes measurements at 1650nm, a wavelength that does not affect the communication wavelengths of 1310/1490/1550nm. It has a built-in cut-off filter to isolate it from wavelengths lower than 1650nm, and so can perform accurate measurements on ‘live’ lines (with active signals). This model is also optimised for testing passive optical networks (PON), and can measure through the high-port- count splitters used in modern PON systems. Model AQ7277B-B02 is designed for monitoring long-distance optical fibres over distances in excess of 200km under real-life environmental conditions. It operates at a wavelength of 1550nm and has a 50dB dynamic range.

XKL, a provider of fibre-optic networking systems, has launched the DQT10 transponder. An extension of the DarkStar DQM10 family of DWDM appliances, the DQT10 muxes wavelengths outside of XKL’s integrated 1RU form factor, thereby allowing networks to grow capacity to 96 channels and be augmented via alien wave injection. Built with flexibility in mind, DQT10 has an integrated digital ROADM providing add/drop functionality that creates circuits between any pair of clients in a topology by soft-selecting the pathway.
The DQT10 is field upgradable from 120G to 240G to 360G and can grow up to 96 channels to offer 960G of bandwidth in 4RU of rack space. Offering customers ultimate control of their bandwidth future, the DQT10 system is easily integrated with XKL’s 100 Gigabit Ethernet products, DQT100, to further increase bandwidth capacity. Like all XKL products, the DQT10 integrates bit error rate (BER) testing, that proves useful when commissioning systems or mitigating potential link issues in an already operational network.
